Male Fertility in Singapore
Male factor contributes to half of all fertility challenges. Here is what a semen analysis shows, what affects sperm quality, and what treatment options exist.
The Role of Male Factor in Infertility
When couples face difficulty conceiving, approximately 30-40% of cases are due to male factor alone, and a further 20-30% involve both partners. Despite this, the male partner is often not investigated until after significant time and money has been spent on female investigations.
A semen analysis is one of the cheapest and most informative fertility tests available ($80-200 at most clinics and hospitals in Singapore). It should be part of the initial fertility workup for any couple who has been trying for 6 months or more without success.
Where to get a semen analysis in Singapore
- - KKH Andrology Lab - $120-180; refer via O&G or urology
- - NUH Urology - similar cost; referral from GP
- - Andrology clinic at private fertility centres (TMC, Sincere IVF) - $150-220; no referral needed
- - Some GPs and polyclinics can arrange collection and send to a lab - check with your doctor
What a Semen Analysis Measures
| Parameter | WHO Normal Value | What It Means |
|---|---|---|
| Volume | 1.4 mL or more | Low volume may indicate blockage or retrograde ejaculation |
| Total sperm count | 39 million or more per ejaculate | Below this is oligozoospermia; no sperm is azoospermia |
| Concentration | 16 million/mL or more | How many sperm are in each millilitre of semen |
| Motility (total) | 42% or more moving | Any forward movement; below this is asthenozoospermia |
| Progressive motility | 30% or more | Sperm swimming in a straight line or large circle - needed to reach the egg |
| Morphology (Kruger strict) | 4% or more normal forms | Percentage with normal head, neck, and tail shape |
| DNA fragmentation (optional) | Under 15-25% (lab-specific) | Damaged sperm DNA reduces IVF success rates; not in standard SA |
WHO 6th Edition reference values (2021). One abnormal result does not mean infertility - always interpret results in clinical context. Repeat the test if initial results are abnormal (2-4 weeks later).
Lifestyle Factors That Affect Sperm Quality
Sperm production takes about 74 days (spermatogenesis). Changes you make today will affect the sperm available 2-3 months from now.
| Factor | Effect on Sperm | Time to Improvement |
|---|---|---|
| Smoking | Reduces count, motility, and morphology; damages sperm DNA | 3 months after quitting |
| Heavy alcohol | Reduces testosterone, lowers count and morphology | 2-3 months after reducing |
| Heat exposure | Hot baths, saunas, tight underwear, laptop on lap - all impair spermatogenesis | 3 months after avoidance |
| Obesity | Lowers testosterone, increases estrogen, reduces count | With weight loss; 3-6 months |
| Anabolic steroids / testosterone | Suppresses sperm production significantly - can cause azoospermia | 6-12+ months after stopping |
| Stress | Raises cortisol; lowers testosterone; moderate effects | Variable |
For men with borderline or abnormal semen analysis, consider supplementing with antioxidants: Zinc 15mg, Vitamin C 500mg, Vitamin E 400IU, CoQ10 200mg. Evidence is modest but these are low-risk. Check at any Guardian or Watson for branded male fertility supplements ($30-80/month).
Treatment for Male Factor Infertility
Treatment depends on the specific cause and severity. Many cases of mild male factor infertility respond to lifestyle changes. More severe cases require assisted reproduction.
Mild male factor - low count or motility
Lifestyle optimisation + 3 months. If no improvement, IUI (intrauterine insemination) places washed sperm directly into the uterus, bypassing the cervix and increasing sperm delivery.
Moderate male factor - count below 5-10 million/mL
IVF with ICSI (intracytoplasmic sperm injection) - a single sperm is injected directly into each egg. Very effective even with low counts.
Azoospermia (no sperm in ejaculate)
Requires specialist investigation to distinguish obstructive azoospermia (blockage - often surgically correctable) from non-obstructive azoospermia (poor sperm production). Surgical sperm retrieval (TESE/PESA) combined with IVF-ICSI can work even with very few sperm recovered.
Refer to a urologist specialising in male fertility (reproductive urologist) at KKH Male Fertility Clinic or NUH Urology for specialist assessment.
