⏱️ Quick Answer
One IVF cycle takes 4–6 weeks of active treatment (stimulation → retrieval → transfer → pregnancy test). Including pre-cycle consultation and testing, the total journey is typically 3–4 months. If a frozen embryo transfer (FET) or genetic testing is involved, add 4–8 weeks. Multiple cycles can span 6–12+ months. In India, a single IVF cycle costs ₹1,00,000–₹3,00,000.
What Is IVF? A Brief Overview
In vitro fertilisation (IVF)is a fertility treatment where eggs are retrieved from a woman's ovaries and fertilised with sperm in a laboratory. The resulting embryo is then transferred to the uterus to establish a pregnancy. The term "in vitro" literally means "in glass," referring to the laboratory dish where fertilisation occurs outside the body.
IVF is recommended when natural conception has been unsuccessful due to factors such as blocked fallopian tubes, low sperm count or motility, endometriosis, ovulation disorders like PCOS, age-related fertility decline, or unexplained infertility. Your fertility specialist may also recommend IVF after IUI (intrauterine insemination) has been unsuccessful.
"IVF can feel overwhelming when you're looking at it as one big process," explains Dr. Priya Sharma. "But when you break it down into individual phases, each step is manageable and has a clear purpose. Understanding the timeline helps patients feel more in control of their journey."

The Complete IVF Timeline: Week-by-Week Breakdown
Here is what a typical IVF journey looks like from your very first appointment to the pregnancy test. Each phase is explained with realistic timeframes, what happens medically, what you'll experience physically and emotionally, and what your partner can expect.
| Phase | Duration | Key Events | Clinic Visits |
|---|---|---|---|
| Phase 0 | 2–4 weeks | Initial consultation, diagnostic tests, treatment plan | 2–3 visits |
| Phase 1 | 10–14 days | Ovarian stimulation (daily injections) | 4–6 monitoring visits |
| Phase 2 | 1 day | Trigger shot → Egg retrieval (36 hours later) | 1 visit (day procedure) |
| Phase 3 | 5–6 days | Fertilisation, embryo culture to blastocyst | Lab updates (phone/email) |
| Phase 4 | 1 day | Embryo transfer | 1 visit (15–20 min) |
| Phase 5 | 10–14 days | Two-week wait → Pregnancy blood test | 1 visit (blood test) |
Phase 0: Pre-IVF Consultation & Testing (2–4 Weeks Before)
Before your IVF cycle begins, your fertility specialist needs a complete picture of your reproductive health. This "discovery phase" involves a series of diagnostic tests that determine your treatment protocol and help predict your response to medication.
Diagnostic tests typically include:
| Test | What It Measures | Why It Matters for IVF |
|---|---|---|
| AMH Blood Test | Ovarian reserve (remaining egg supply) | Determines medication dosage and expected egg yield |
| Antral Follicle Count (AFC) | Number of resting follicles visible on ultrasound | Predicts ovarian response to stimulation |
| FSH, LH, Estradiol | Baseline hormone levels | Confirms ovarian function and cycle timing |
| HSG / Saline Sonogram | Fallopian tube patency and uterine cavity shape | Identifies structural issues that could affect implantation |
| Semen Analysis | Sperm count, motility, morphology | Determines if standard IVF or ICSI is needed |
| Infectious Disease Panel | HIV, Hepatitis B/C, syphilis, rubella | Mandatory safety screening before any procedure |
| Thyroid Panel (TSH) | Thyroid function | Thyroid disorders can affect implantation and pregnancy |
🇮🇳 India Context: In India, this initial testing phase typically costs ₹5,000–₹15,000 across pathology labs and the fertility clinic. Many clinics include these tests in their IVF package. See our complete fertility testing guide →
What your partner does: The male partner provides a semen sample for analysis. If results are abnormal, the specialist may recommend further evaluation. Read our guide on improving sperm health →
Phase 1: Ovarian Stimulation (Days 1–14)
Your IVF cycle officially begins on Day 1 of your menstrual period. You'll contact your clinic to confirm the start date, and within the first 2–3 days, you'll begin daily hormone injections to stimulate your ovaries to produce multiple follicles — each containing a potential egg.
In a natural cycle, only one egg matures each month. IVF stimulation aims to safely grow 8–15 follicles to give you the best chance of creating multiple embryos. More embryos mean more chances — either for this cycle or for future frozen transfers.
Common medications used during stimulation:
- Gonadotropins (FSH/LH) — Gonal-F, Follistim, Menopur — these are the primary stimulation drugs that promote follicle growth
- GnRH Antagonists — Cetrotide, Ganirelix — started around day 5–6 to prevent premature ovulation
- GnRH Agonists — Lupron — used in some protocols (long protocol) for control of ovulation timing
Monitoring schedule:
- Days 1–4: Baseline blood test and ultrasound; begin injections
- Days 5–7: First monitoring visit — blood test (estradiol) + transvaginal ultrasound to check follicle growth
- Days 8–12: Monitoring every 2–3 days — medication doses may be adjusted based on follicle size and hormone levels
- Day 10–14: When follicles reach 17–22mm, you receive the "trigger shot" (Ovidrel or Lupron) — this triggers final egg maturation exactly 34–36 hours before retrieval
💪 What you may feel: Bloating, mild cramping, breast tenderness, mood changes, and mild headaches are common during stimulation. Your ovaries are growing to several times their normal size, so some discomfort is expected. Your medical team monitors you closely to ensure safe follicle growth and to reduce the risk of Ovarian Hyperstimulation Syndrome (OHSS).
Work/life tip: Most monitoring appointments are early morning (7–9 AM) and take 30–60 minutes including wait time. Many patients continue working normally during this phase. Plan for 4–6 clinic visits during stimulation.
Phase 2: Egg Retrieval (Day 14–15)
Egg retrieval (also called "egg pick-up" or EPU) is a minor day procedure performed exactly 34–36 hours after the trigger shot. Using high-resolution transvaginal ultrasound guidance, your fertility specialist passes a fine needle through the vaginal wall into each ovary to aspirate the fluid from each mature follicle.
What to expect:
- Duration: 20–30 minutes under light sedation or general anaesthesia — you'll be asleep and feel nothing
- Average eggs retrieved: 8–15, though this varies by age and ovarian reserve. Women under 35 typically yield more eggs than women over 40
- Recovery: 1–2 hours in the recovery room, then home. You'll need someone to drive you. Rest for 24–48 hours. Mild cramping and bloating are normal
- Rare complications: Ovarian Hyperstimulation Syndrome (OHSS), infection, or bleeding — your team monitors for these
What your partner does: On the morning of egg retrieval, your partner provides a fresh sperm sample at the clinic. If using frozen or donor sperm, the lab prepares the sample in advance. The lab team then isolates the healthiest sperm for fertilisation.
Phase 3: Fertilisation & Embryo Development (Days 15–20)
After retrieval, the collected eggs are examined by embryologists and combined with prepared sperm. Fertilisation can occur via two methods:
- Standard IVF: Eggs and sperm are placed together in a culture dish, allowing natural fertilisation
- ICSI (Intracytoplasmic Sperm Injection): A single healthy sperm is injected directly into each mature egg — recommended when sperm quality is a concern, or when previous IVF had low fertilisation rates
Embryo development day by day:
| Day | Stage | What's Happening | Expected Size |
|---|---|---|---|
| Day 0 | Fertilisation | Sperm and egg combine; pronuclei (2PN) appear ~17 hours later | Single cell |
| Day 1 | Zygote | Fertilisation confirmed — 2 pronuclei visible (one from egg, one from sperm) | 1 cell |
| Day 2 | Cleavage | First cell divisions | 2–4 cells |
| Day 3 | Cleavage | Continued division — some clinics transfer at this stage | 6–8 cells |
| Day 4 | Morula | Cells compact into a solid ball | 16–32 cells |
| Day 5–6 | Blastocyst | Fluid-filled cavity forms; inner cell mass (future baby) and trophectoderm (future placenta) differentiate | ~100+ cells |
⚠️ Important reality check: Not all eggs will fertilise, and not all fertilised eggs will reach the blastocyst stage. On average, about 70–80% of mature eggs fertilise, and approximately 40–60% of fertilised eggs develop to blastocyst. This attrition is completely normal — it reflects the natural selection process. Your clinic will keep you updated on your embryo development.
Phase 4: Embryo Transfer (Day 19–20)
Once a healthy blastocyst has developed, the next step is embryo transfer — a quick, painless procedure where the embryo is placed into your uterus. Most clinics now transfer a single embryo to minimise the risk of multiple pregnancies.
What happens during the procedure:
- An embryologist loads the selected embryo into a very fine, flexible catheter
- Your fertility specialist gently guides the catheter through the cervix and releases the embryo into the uterus — guided by ultrasound
- The entire procedure takes 5–15 minutes
- No anaesthesia is needed — it feels similar to a Pap smear
- You can get up and leave shortly after — the embryo will not fall out
Any additional viable embryos are cryopreserved (frozen) for future use. This is important — frozen embryos give you the option of another transfer without repeating the entire stimulation and retrieval process.
Phase 5: The Two-Week Wait & Pregnancy Test (Days 20–34)
After transfer, you enter the "two-week wait" (2WW) — the period between embryo transfer and the pregnancy blood test. This 10–14 day period is often described as the most emotionally challenging part of the entire IVF process.
During the two-week wait:
- You'll continue taking progesterone (pessaries, injections, or oral tablets) to support the uterine lining
- Continue normal daily activities — walking, light work, and gentle movement are fine
- Avoid: Strenuous exercise, hot baths/saunas, alcohol, smoking, and heavy lifting
- Don't use home pregnancy tests early — they can give false results due to the trigger shot (hCG) still in your system
At the end of the wait, you'll have a beta hCG blood testat your clinic. This measures the level of human chorionic gonadotropin in your blood — the hormone produced by a developing embryo after implantation. A positive result indicates pregnancy, and you'll have a follow-up ultrasound at 6–7 weeks to confirm a heartbeat.
💡 Emotional tip: The two-week wait can be intensely stressful. Plan activities that keep you distracted — a short trip, a creative project, time with supportive friends. Many clinics offer counselling support during this period. Remember: feeling anxious is completely normal and does NOT affect your outcome. There is no evidence that stress during the 2WW reduces implantation success.
Fresh vs Frozen Embryo Transfer: Timeline Comparison
One of the most important decisions in your IVF journey is whether to proceed with a fresh embryo transfer (immediately after egg retrieval) or a frozen embryo transfer (FET) in a later cycle. This decision significantly affects your overall timeline.
| Factor | Fresh Transfer | Frozen Embryo Transfer (FET) |
|---|---|---|
| Total timeline | 4–6 weeks (one continuous cycle) | 8–12 weeks (stimulation cycle + FET cycle) |
| When transfer occurs | Day 3 or Day 5 after egg retrieval | 4–8 weeks after retrieval in a separate cycle |
| Uterine preparation | Uterus exposed to stimulation hormones | Uterus recovered and prepared with controlled medication |
| Success rates | Comparable in many cases | Often comparable or slightly higher — especially for women 35+ |
| OHSS risk | Higher (hormones still elevated) | Lower (body has recovered) |
| Allows PGT | Only if results arrive within 5 days (rare) | Yes — standard approach for genetically tested embryos |
| Cost | Included in IVF cycle cost | Additional FET cycle fee (₹30,000–₹60,000 in India) |
"The medical community has increasingly shifted toward frozen embryo transfers," explains Dr. Priya Sharma. "Freezing allows the body to recover from stimulation, the uterine lining to develop in a more natural hormonal environment, and genetic testing to be completed. For many patients, FET offers the best balance of safety and success."
🇮🇳 India Context: Most top-tier IVF clinics in India now offer vitrification (ultra-rapid freezing) with embryo survival rates exceeding 95%. A standalone FET cycle costs approximately ₹30,000–₹60,000 in addition to the initial IVF cycle fee. Estimate your total IVF cost →
How Genetic Testing (PGT) Affects Your Timeline
Preimplantation Genetic Testing (PGT) is an optional but increasingly common step in IVF that screens embryos for genetic or chromosomal abnormalities before transfer. While it adds time to the process, it can significantly improve outcomes by ensuring only chromosomally normal (euploid) embryos are transferred.
| Type | What It Tests For | Who It's For | Time Added |
|---|---|---|---|
| PGT-A | Chromosomal aneuploidy (extra/missing chromosomes) | Women 35+, recurrent miscarriage, repeated IVF failure | 2–4 weeks for results |
| PGT-M | Specific single-gene disorders (e.g., thalassemia, sickle cell, cystic fibrosis) | Couples who are known carriers of genetic diseases | 3–4 weeks for results |
| PGT-SR | Structural chromosomal rearrangements (translocations) | Couples with known chromosomal rearrangements | 2–4 weeks for results |
How PGT changes the IVF timeline:
- Embryos are cultured to the blastocyst stage (Day 5–6)
- A few cells are biopsied from the trophectoderm (outer layer — this does NOT damage the embryo)
- All biopsied embryos are vitrified (frozen) immediately
- Biopsy samples are sent to a genetics laboratory — results take 1–3 weeks
- Once results are available, a FET cycle is scheduled — adding another 4–6 weeks
Total additional time: PGT adds approximately 6–10 weeks to your overall IVF timeline. However, by selecting only chromosomally normal embryos, it can reduce miscarriage risk and improve the chance of a healthy pregnancy — potentially saving time that would otherwise be spent on failed transfers.
🇮🇳 India Context: PGT-A costs approximately ₹30,000–₹60,000 in India (for up to 8 embryos). PGT-M requires a custom probe preparation that costs an additional ₹40,000–₹80,000. This is significantly cheaper than comparable testing in the US ($3,000–$6,000) or UK (£2,000–£3,500).
IVF Timeline by Age: What Changes?
Your age significantly influences not just IVF success rates, but also the timeline itself. Older patients may require different stimulation protocols, could need more cycles, and are more likely to benefit from genetic testing — all of which extend the overall journey.
| Age Group | Typical Protocol | Avg. Eggs Retrieved | Live Birth Rate / Transfer | Expected Timeline |
|---|---|---|---|---|
| Under 35 | Standard stimulation | 10–20 | 40–55% | 3–4 months (1 cycle often sufficient) |
| 35–37 | Standard or slightly higher dose | 8–15 | 30–45% | 4–6 months (may need 1–2 cycles) |
| 38–40 | Higher dose; PGT-A often recommended | 5–10 | 20–30% | 6–9 months (plan for 2–3 cycles) |
| 41–42 | Aggressive stimulation or mini-IVF; PGT-A recommended | 3–8 | 10–20% | 9–12+ months (multiple cycles likely) |
| Over 42 | May consider donor eggs | 1–5 (own eggs) | <10% (own eggs); 50–60% (donor) | Highly variable; donor egg IVF: 3–4 months |
⚠️ Key insight: The primary reason for age-related decline is not egg quantity but egg quality. After age 35, the percentage of chromosomally normal (euploid) embryos decreases significantly. At 40, approximately 60–70% of embryos are chromosomally abnormal. This is why PGT-A becomes more valuable with age — it identifies the best embryos and avoids transferring those destined to fail.
Cumulative success rates — the chance of achieving a live birth across multiple cycles — are significantly higher than single-cycle rates. For women under 38, cumulative success after 3 cycles can reach 60–70%. This is an important perspective: IVF is often a journey of multiple attempts, not a single "all or nothing" event.

What Happens If Your IVF Cycle Fails?
A failed IVF cycle is emotionally devastating, and it's important to acknowledge that grief, frustration, and anxiety are completely normal responses. But a failed first cycle does not mean IVF will never work. In many cases, the first cycle provides valuable information that helps your specialist optimise the next attempt.
If Egg Retrieval Yields Few or No Eggs
This can happen if the ovarian response to stimulation is poor. Your doctor will typically recommend waiting 1–2 menstrual cycles(4–8 weeks) before trying again, during which time medication protocols may be adjusted. Some patients benefit from "priming" protocols with DHEA, CoQ10, or growth hormone supplements during this gap.
If Fertilisation Fails or Embryos Don't Develop
If eggs fail to fertilise with standard IVF, your doctor may recommend ICSI for the next cycle. If embryos arrest (stop developing) before blastocyst stage, the lab may adjust culture conditions, or your specialist may recommend further testing such as sperm DNA fragmentation analysis.
If Embryo Transfer Fails (Negative Pregnancy Test)
A failed transfer is the most common outcome to plan for, especially in first cycles. The good news is that if you have frozen embryos remaining, you can proceed with a frozen embryo transfer (FET) cycle as soon as your next period — without repeating stimulation and retrieval. A FET cycle takes only 4–6 weeks.
If no frozen embryos remain, your specialist will recommend waiting 1–3 months before starting a new full IVF cycle. During this time, your doctor may recommend:
- Adjusting stimulation medication dosage or protocol
- Additional testing — hysteroscopy to check the uterine cavity, endometrial receptivity analysis (ERA), or immune testing
- Lifestyle optimisation — diet, supplements, stress management
- Changing from fresh transfer to FET approach (or vice versa)
💡 Perspective: Research shows that cumulative IVF success rates improve significantly across multiple cycles. Many fertility specialists recommend attempting at least 3 cycles before considering alternative approaches. Each cycle teaches your medical team more about how your body responds, allowing for increasingly refined protocols.
IVF Timeline for Special Situations
IVF with Donor Eggs
If you're using donor eggs, the egg donor undergoes ovarian stimulation and retrieval while your uterus is simultaneously prepared with hormone medication. The overall timeline is similar to a standard cycle (4–6 weeks for the treatment phase), but the matching and legal processcan add 1–3 months beforehand. Success rates with donor eggs are typically 50–60% per transfer, regardless of the recipient's age.
IVF with Donor Sperm
Using donor sperm does not significantly change the IVF timeline. Donor sperm is pre-screened, frozen, and readily available through registered sperm banks. The standard IVF or ICSI process proceeds normally. In India, donor sperm costs approximately ₹5,000–₹15,000.
IVF After Egg Freezing
If you previously froze your eggs, the retrieval phase is eliminated entirely. The timeline involves thawing eggs, fertilising them with sperm (usually via ICSI), culturing embryos to blastocyst stage (5–6 days), and then an embryo transfer. The active treatment phase is approximately 3–4 weeks.
Mini-IVF (Minimal Stimulation IVF)
Mini-IVF uses lower doses of medication or oral medications (e.g., clomiphene citrate) to produce fewer eggs (typically 2–5). The stimulation phase may be shorter (7–10 days), and the overall cycle is more compact. However, fewer eggs mean fewer embryos, which may necessitate more cycles. Mini-IVF is sometimes preferred for women over 40 with low ovarian reserve.
Natural Cycle IVF
Natural cycle IVF retrieves the single egg your body produces naturally — no stimulation injections at all. The cycle follows your natural menstrual pattern, with monitoring in the lead-up to ovulation. While the most gentle protocol, success rates per cycle are lower (10–15%), and multiple cycles are typically needed.
How Much Does IVF Cost? (Worldwide Comparison)
IVF costs vary dramatically across countries. India has emerged as a major destination for medical tourism in fertility treatment, offering high-quality care at a fraction of Western prices. Here is a comprehensive comparison:

Preparing for IVF: Physical, Emotional & Lifestyle Tips
While you cannot control the outcome of IVF, optimising your health before and during treatment can support your body's readiness. Here are evidence-based recommendations from fertility specialists worldwide:
Physical Preparation (Start 2–3 Months Before)
Follow a Mediterranean-Style Diet
Research links this diet pattern to improved IVF outcomes. Prioritise fruits, vegetables, whole grains, healthy fats (olive oil, nuts, avocados), lean protein, and omega-3 rich fish. Minimise processed foods, refined sugar, and trans fats.
Start Key Supplements (With Doctor Approval)
Prenatal vitamins with folic acid (400–800 mcg), Vitamin D (1000–2000 IU), Coenzyme Q10 (200–600 mg — supports egg quality), and Omega-3 fatty acids. Always consult your specialist before starting any supplements.
Exercise — But Keep It Moderate
Walking, swimming, yoga, and gentle Pilates are ideal. Avoid high-intensity training, heavy weightlifting, and marathon running, especially during stimulation. Aim for 30 minutes of moderate activity 5 days/week.
Maintain a Healthy BMI (18.5–24.9)
Being significantly overweight or underweight can affect IVF success. Even modest weight changes (5–10% reduction if overweight) can improve hormonal balance and ovarian response.
Eliminate Harmful Substances
Stop smoking (both partners), eliminate alcohol, limit caffeine to 1–2 cups/day, and avoid recreational drugs. In India, this includes gutka, pan masala, and all tobacco products.
Sleep 7–9 Hours Nightly
Quality sleep supports hormonal regulation. Maintain a consistent sleep schedule. Melatonin (a sleep hormone) has antioxidant properties that may support egg quality — some clinics recommend low-dose melatonin supplementation.
See our complete fertility diet plan → | Yoga practices for fertility →
Emotional Preparation
The emotional toll of IVF is often underestimated. Studies show that IVF patients experience stress levels comparable to patients dealing with cancer or heart disease. Here's how to protect your mental health:
- Educate yourself: Understanding the process reduces fear of the unknown. This guide is a good start
- Build a support system: Tell a few trusted people about your journey. Consider joining an IVF support group (online or in-person)
- Communicate with your partner: Schedule "non-IVF" time together. Discuss expectations, fears, and boundaries openly
- Consider counselling: Many fertility clinics offer specialised counselling. A therapist experienced in fertility issues can provide coping strategies
- Set boundaries: You don't owe anyone an explanation about your treatment. It's okay to decline baby showers or family gatherings if they feel too painful
- Practice mindfulness: Meditation, deep breathing, and journaling can help manage anxiety, especially during the two-week wait
Work & Logistics Planning
- Plan for 4–6 clinic visits during the stimulation phase (usually early morning, 30–60 minutes each)
- Take 1–2 days off for egg retrieval and the day after for rest
- Embryo transfer requires only a few hours — some patients return to work the same day
- Consider telling your manager (if comfortable) — you may need flexibility for morning appointments
- Stock your freezer with easy meals for the weeks when you may not feel like cooking
Frequently Asked Questions
How long does one IVF cycle take from start to finish?
A single IVF cycle typically takes 4–6 weeks of active treatment — from the first day of ovarian stimulation to the pregnancy blood test. However, when you include the initial consultation, diagnostic testing, and pre-cycle preparation, the total journey from first appointment to pregnancy test is usually 3–4 months.
How many days of injections are needed for IVF?
Ovarian stimulation injections are administered daily for 8–14 days, with most patients requiring 10–12 days. The exact duration depends on how your ovaries respond to the medication, which is monitored through blood tests and ultrasounds every 2–3 days.
Is the egg retrieval procedure painful?
Egg retrieval is performed under light sedation or general anaesthesia, so you will not feel pain during the procedure. It takes 20–30 minutes. Afterward, you may experience mild cramping, bloating, or discomfort for 24–48 hours. Most patients return to normal activities within 1–2 days.
How long after egg retrieval is embryo transfer?
For a fresh embryo transfer, the transfer occurs 3–5 days after egg retrieval (usually day 5, at the blastocyst stage). For a frozen embryo transfer (FET), there is a gap of at least 4–6 weeks between retrieval and transfer, as the body needs time to recover and the uterine lining must be prepared.
What is the two-week wait in IVF?
The two-week wait (2WW) is the period between embryo transfer and the pregnancy blood test (beta hCG). It lasts 10–14 days. During this time, the embryo is attempting to implant in the uterine lining. Most doctors advise normal daily activities but avoiding strenuous exercise and hot baths.
How long does a frozen embryo transfer (FET) cycle take?
A FET cycle typically takes 4–6 weeks. This includes 2–3 weeks of medications to prepare the uterine lining (estrogen and progesterone), the transfer itself (5 minutes), and then the 2-week wait for the pregnancy test. FET does not require ovarian stimulation or egg retrieval.
Does genetic testing (PGT) make IVF take longer?
Yes. If you opt for Preimplantation Genetic Testing (PGT-A or PGT-M), embryos are biopsied at the blastocyst stage, frozen, and sent to a genetics laboratory. Results take 1–3 weeks. The transfer then occurs in a subsequent FET cycle, adding approximately 4–8 weeks to the total timeline.
How many IVF cycles does it take to get pregnant?
This varies significantly by age. Women under 35 have a 40–55% live birth rate per cycle, while women over 40 may have 10–20%. Cumulative success rates across 3 cycles are significantly higher — up to 60–70% for women under 38. Many patients achieve pregnancy within 2–3 cycles.
Can I work during IVF treatment?
Yes, most patients continue working during IVF. The main time commitments are monitoring appointments during stimulation (every 2–3 days, usually early morning) and 1–2 days off for egg retrieval. Embryo transfer requires only a few hours. Some patients take the day of retrieval and the following day off work.
How long should I wait between IVF cycles?
Most fertility specialists recommend waiting at least one full menstrual cycle (4–6 weeks) between a failed IVF cycle and the next attempt. This allows the ovaries to recover from stimulation. Some doctors recommend waiting 2–3 months, especially if ovarian hyperstimulation occurred.
What is the IVF success rate by age?
Using own eggs: Under 35 — 40–55% live birth rate per transfer. Ages 35–37 — 30–45%. Ages 38–40 — 20–30%. Ages 41–42 — 10–20%. Over 42 — under 10%. Using donor eggs eliminates the age factor, with success rates of 50–60% regardless of recipient age.
How much does IVF cost worldwide?
IVF costs vary dramatically by country. India: ₹1,00,000–₹3,00,000 ($1,200–$4,000) per cycle. UK: £5,000–£8,000 ($6,500–$10,500). Australia: AUD 8,000–12,000 ($6,000–$8,000). USA: $12,000–$25,000+. These are base costs — medications, ICSI, PGT, and cryopreservation add extra.
Is IVF painful?
Most steps involve mild discomfort rather than significant pain. The daily stimulation injections use very fine needles and most patients adapt within 1–2 days. Egg retrieval is done under anaesthesia so you feel nothing. Embryo transfer is similar to a Pap smear. The most challenging aspect for many patients is the emotional stress rather than physical pain.
What medications are used during IVF?
Common IVF medications include: gonadotropins (FSH/LH) for ovarian stimulation (e.g., Gonal-F, Menopur, Follistim), GnRH antagonists to prevent premature ovulation (e.g., Cetrotide, Ganirelix), a trigger shot for final egg maturation (e.g., Ovidrel, Lupron), and progesterone for luteal support after transfer.
Can I travel during IVF treatment?
During ovarian stimulation, you need to be near your clinic for monitoring every 2–3 days. After egg retrieval, rest for 24–48 hours before any travel. After embryo transfer, avoid long flights or strenuous travel for 48–72 hours. During the two-week wait, normal travel is generally fine, but confirm with your doctor.
