A semen analysis is the first and most important test for evaluating male fertility. It assesses sperm count, motility (movement), and morphology (shape). About 40% of infertility cases involve male factors.
WHO Normal Reference Values (2021)
Parameter
Normal Value
What It Means
Volume
≥1.5 mL
Amount of ejaculate; low volume may indicate blockage or hormonal issue
Sperm Concentration
≥16 million/mL
Number of sperm per mL of semen
Total Sperm Count
≥39 million
Total number in the entire sample
Progressive Motility
≥30%
Percentage of sperm that move forward effectively
Total Motility
≥42%
All sperm that show any movement
Normal Morphology
≥4%
Percentage of normally shaped sperm (Kruger strict criteria)
Vitality
≥54%
Percentage of live sperm
pH
≥7.2

Understanding Abnormal Results
Diagnosis
Meaning
Treatment Options
Oligozoospermia
Low sperm count (<16M/mL)
Lifestyle changes, medications, IUI, ICSI
Asthenozoospermia
Poor motility (<30% progressive)
Antioxidants, ICSI if severe
Teratozoospermia
Abnormal shape (<4% normal)
ICSI — allows selection of best sperm
Azoospermia
Zero sperm in ejaculate
Surgical retrieval (TESA/MESA) + ICSI
OAT Syndrome
Low count + low motility + abnormal shape
IVF + ICSI; donor sperm if very severe

How Men Can Improve Sperm Quality
Quit smoking — reduces sperm count by 20% and motility by 15%
Limit alcohol — more than 14 drinks/week lowers testosterone and sperm production
Avoid heat — no hot baths, saunas, or laptops on the lap; wear loose underwear
Medical Disclaimer: A single semen analysis does not define fertility. Parameters fluctuate significantly. Always get at least 2 tests and discuss results with a reproductive urologist or fertility specialist.
