The single most important fact about infertility is the one most couples learn late: roughly half of it is male.
Male factors account for something close to half of all cases, either alone or alongside a female factor.
Yet the usual sequence is that the woman undergoes months of blood tests, scans and tube investigations first, and the semen analysis happens afterwards, despite it being the cheapest, fastest and least invasive test in the whole workup.
Do it first, and do it at the same time as anything else. If either of you is being tested, both of you should be.
When to seek help
- After 12 months of regular unprotected sex without conception
- After 6 months if the woman is 35 or over: the shorter timeline is important, because time is the variable you can’t recover
- Straight away if there’s a known reason to expect difficulty: irregular or absent periods, known endometriosis or PCOS, previous pelvic surgery or infection, undescended testes, previous chemotherapy, or two or more miscarriages
Around one in six couples worldwide has difficulty conceiving. It’s far more common than the silence around it suggests.
What’s usually behind it
|
| Female factors |
Male factors |
| Ovulation disorders, of which PCOS is the most common |
Low sperm count, motility or abnormal morphology |
| Blocked or damaged fallopian tubes, often after infection or surgery |
Varicocele: enlarged veins in the scrotum, and often treatable |
| Endometriosis |
Blockage or absence of the ducts |
| Fibroids or uterine abnormalities |
Hormonal problems |
| Age-related decline in egg quality |
Previous surgery, infection or treatment |
About one in four cases is unexplained, which is a real diagnosis, not a failure to look properly, and it’s compatible with successful treatment.
What the investigation involves
- Semen analysis. First, always. A single abnormal result is usually repeated, since counts vary.
- Blood tests for hormones, typically early in the cycle, plus AMH as an indicator of ovarian reserve.
- Pelvic ultrasound for the uterus and ovaries, and to count follicles.
- A tubal test to check the fallopian tubes are open.
- Confirming ovulation, usually with a blood test in the second half of the cycle.
The usual order of treatments
- Timing and lifestyle changes, which fix more cases than people expect. See below.
- Ovulation induction with tablets, for women who aren’t ovulating regularly.
- Intrauterine insemination (IUI), where prepared sperm is placed in the uterus around ovulation.
- IVF, where eggs are collected and fertilised outside the body.
- ICSI, where a single sperm is injected into an egg, the usual approach for significant male factor.
- Surgery for specific problems such as fibroids, endometriosis or a varicocele.
What to do in Singapore
- Start with a GP or your gynaecologist, who can arrange the first tests and refer you on.
- Public hospitals. KKH, NUH and SGH run assisted reproduction services, generally at lower cost than private clinics, with waiting times.
- Government co-funding for assisted reproduction is available to eligible couples at public centres, with conditions including age and citizenship.
- MediSave can be used for assisted reproduction treatment, with per-cycle limits and a lifetime cap.
- Rules and amounts change: check the current position with the hospital or the Ministry of Health instead of relying on any article.
- Ask about total cost per cycle, including medication, which is often quoted separately and is a substantial part of it.
Things to do regardless
- Timing. The fertile window is the five days before ovulation and the day of it. Sex every two to three days across the cycle covers it without turning the whole thing into a schedule.
- Stop smoking, both of you. It affects egg quality and sperm quality measurably.
- Weight matters in both directions, and for both partners.
- Reduce alcohol.
- Heat affects sperm production. Saunas, hot tubs and laptops on laps are best avoided while trying.
- Folic acid for her, started before conception, not after.
- Review medications with a doctor. Some affect fertility on either side.
The part clinics handle least well
Infertility treatment is emotionally punishing in a way that’s rarely acknowledged in the consultation room: a two-week wait every cycle, appointments that consume annual leave, injections, and a monthly verdict.
- It puts real strain on a relationship, partly because blame attaches itself to whoever’s test came back abnormal. It’s a shared problem regardless of whose body it’s in.
- Partners often grieve differently and at different speeds, which each can misread as not caring.
- Decide in advance how much you’ll do: how many cycles, what you’ll spend, when you’ll stop or change direction. Making that decision while exhausted mid-treatment is much harder.
- Ask about counselling. Fertility clinics can usually arrange it and very few couples take it up.
- Protect yourself socially. You’re allowed to skip the baby shower.
Frequently asked questions
When should we see a doctor about not conceiving?
After 12 months of regular unprotected sex, or after 6 months if the woman is 35 or over. Go straight away if there’s a known reason to expect difficulty: irregular or absent periods, known PCOS or endometriosis, previous pelvic surgery or infection, undescended testes, previous chemotherapy, or two or more miscarriages.
Is infertility usually the woman’s problem?
No. Male factors account for close to half of all cases, alone or in combination. Yet the semen analysis, the cheapest, quickest and least invasive test available, is frequently done after months of investigating the woman. Both partners should be tested at the same time.
What tests are involved?
Semen analysis first. Then hormone blood tests early in the cycle plus AMH for ovarian reserve, a pelvic ultrasound, a test to check the fallopian tubes are open, and confirmation of ovulation. A single abnormal semen result is usually repeated, since counts vary.
What are the treatment options?
Timing and lifestyle changes first, then ovulation induction tablets for women not ovulating regularly, intrauterine insemination, IVF, and ICSI where a single sperm is injected into an egg, the usual route for significant male factor. Surgery addresses specific problems such as fibroids, endometriosis or a varicocele.
Can I use MediSave for fertility treatment in Singapore?
Yes, for assisted reproduction treatment, subject to per-cycle limits and a lifetime cap. Government co-funding is also available to eligible couples at public centres, with conditions including age and citizenship. Rules and amounts change, so confirm the current position with the hospital or Ministry of Health.
When is the fertile window?
The five days before ovulation and the day of ovulation itself. Sex every two to three days across the cycle covers it without needing to track anything, which many couples find easier to sustain than a schedule.
What if no cause is found?
Around one in four cases is unexplained. That’s a real category, not a failure to investigate properly, and it remains compatible with successful treatment.
What to remember
Get the semen analysis done first. Half of infertility is male, and it’s the cheapest and fastest test there is. Doing it after months of investigating her is the standard mistake.
Twelve months of trying, or six if she is over 35. Sooner if there’s a known reason.
Decide in advance how many cycles and how much money before you’re exhausted and deciding mid-treatment. And ask about counselling, which almost nobody does.
