What is Unexplained Infertility?
Unexplained Infertility is diagnosed when a couple cannot conceive after 12 months of regular unprotected intercourse. All standard fertility tests come back normal. This includes semen analysis, ovulation assessment, HSG, and hormonal panels. No identifiable cause is found. It accounts for about 25–30% of all infertility cases. Treatment follows a stepwise approach: ovulation induction and timed intercourse first, then IUI, then IVF if needed.
🇮🇳 India Context: Unexplained Infertility is widely available across major Indian cities. These include Chennai, Mumbai, Bangalore, Delhi, and Hyderabad. India offers world-class fertility care at significantly lower costs than Western countries.
Why Unexplained Infertility Matters
Understanding unexplained infertility is important for anyone dealing with fertility challenges. Your doctor may recommend this evaluation based on your diagnosis, health history, and goals.
This condition is a common cause of infertility in India. Early diagnosis and treatment can greatly improve your chances of conceiving. Many couples with this condition go on to have successful pregnancies with the right care.
How Unexplained Infertility Works
Here is what you can expect during the diagnosis and treatment process:
Success Rate & Effectiveness
Unexplained Infertility has a reported effectiveness of IUI: 10–15% per cycle; IVF: 40–50% per cycle in India. Success rates vary. Key factors include age, underlying diagnosis, clinic expertise, and overall health.
💡 Key Insight: Clinics measure success rates in different ways. Always ask your doctor what the number means. Does it refer to a pregnancy rate, clinical pregnancy rate, or live birth rate? Is it per cycle, per transfer, or across multiple cycles?
Cost of Unexplained Infertility in India
The typical cost of unexplained infertility in India ranges from IUI: ₹10,000–₹35,000; IVF: ₹1,00,000–₹3,00,000. Costs can vary based on the city, clinic reputation, doctor experience, and any additional procedures or medications required.
India offers this at a much lower cost than Western countries. The US charges 3–5x more, the UK 2–4x more, and Australia 2–3x more. This makes India a top destination for fertility treatment.

IUI (Intrauterine Insemination)
IUI (Intrauterine Insemination) is a fertility treatment where washed, concentrated sperm is placed directly into the uterus through a thin catheter. This is done around the time of ovulation. It bypasses the cervix, putting sperm closer to the egg. IUI is used for mild male factor infertility, cervical mucus problems, ovulation disorders, or unexplained infertility. The aim is to increase the number of healthy sperm reaching the fallopian tubes.
IVF (In Vitro Fertilisation)
IVF (In Vitro Fertilisation) is an assisted reproductive technology (ART) in which eggs are retrieved from the ovaries and fertilised with sperm outside the body in a controlled laboratory environment, and the resulting embryo is then transferred into the uterus to achieve pregnancy. IVF is used to help individuals or couples overcome fertility challenges such as blocked fallopian tubes, ovulation disorders, male factor infertility, or unexplained infertility, with the goal of increasing the chances of successful conception when natural methods or simpler treatments like IUI have not been effective.
Ovulation Induction
Ovulation Induction is a fertility treatment that uses medications to stimulate the ovaries. Oral drugs like Letrozole or Clomiphene, or injectable hormones, are used. The goal is to trigger the development and release of one or more mature eggs. It is used for women with irregular or absent ovulation — including those with PCOS or hypothalamic amenorrhea. Treatment can support natural conception through timed intercourse, or be combined with IUI.
HSG Test (Hysterosalpingography)
HSG (Hysterosalpingography) is a diagnostic X-ray procedure. A contrast dye is injected through the cervix into the uterus and fallopian tubes. X-ray images show whether the tubes are open or blocked. It also reveals the shape of the uterine cavity. Doctors use HSG to identify blocked tubes, polyps, fibroids, or a septate uterus that may be preventing pregnancy.
Semen Analysis
Semen Analysis is the main test for evaluating male fertility. A semen sample is examined under a microscope. The lab checks sperm count, motility (movement), morphology (shape), volume, and pH. It is one of the first tests done when a couple is having difficulty conceiving. Results can identify low sperm count, poor motility, or abnormal morphology. These findings guide the next steps — from lifestyle changes to IUI or ICSI.
