PCOS and Fertility in Singapore: IVF Co-Funding, Where to Go, and Getting Metabolically Ready

If you have PCOS (now formally renamed PMOS, Polyendocrine Metabolic Ovarian Syndrome) and you're trying to conceive, the first thing worth knowing is the least-said thing: PCOS is the single most common cause of anovulatory infertility, and it's also one of the most treatable. The problem is usually a missing ovulation, not a broken one—and ovulation is something medicine is quite good at bringing back.

What Singapore adds to that picture is a specific care system, with specific costs and a co-funding scheme many couples don't realise they qualify for. This is the map: the treatment ladder, where to go, what it costs, and the metabolic prep that quietly improves the odds at every rung.

The good news: it's a treatable kind of infertility

With PMOS, the ovaries usually contain plenty of eggs—the follicles just stall before releasing one. So fertility care starts not with IVF but with ovulation induction: gentle medication to prompt a single egg to mature and release.

The 2023 International PCOS Guideline (still the working standard while the rename beds in) names letrozole as the first-line ovulation-induction drug, ahead of the older clomiphene, because it produces higher live-birth rates in PCOS with fewer multiples. If letrozole alone doesn't work, the ladder continues: adding metformin, then injectable gonadotropins or IUI, and only then IVF. Many women conceive on the lower rungs and never need the top one. That matters in Singapore, because the lower rungs are also far cheaper.

Where to go in Singapore

Fertility care here runs on two tracks:

• Public assisted-reproduction (AR) centres — KK Women's and Children's Hospital (KKH), National University Hospital (NUH), and Singapore General Hospital (SGH). These are the centres eligible for government co-funding (below), and the usual starting point if cost matters.
• Private clinics and hospitals — faster access and continuity with one specialist, but co-funding does not apply to purely private cycles.

For most women with PMOS, the sensible entry point is a GP or polyclinic referral to a public AR centre, or a gynaecologist who does fertility work. You generally don't need to have "failed" for years first—if cycles are irregular and you're trying to conceive, that's already the signal to start the conversation. If you're still working out which kind of doctor to see, our guide on finding a PCOS specialist in Singapore covers the endocrinologist-versus-gynaecologist question.

What it costs — and the co-funding most couples miss

This is the part worth reading twice. For eligible couples at public AR centres, the government co-funds up to 75% of the treatment cost — up to S$7,700 per fresh IVF cycle and S$2,200 per frozen cycle (Ministry of Health co-funding scheme). MediSave can then be used for part of the remaining bill.

The main eligibility conditions:

• At least one spouse is a Singapore Citizen at the start of the cycle.
• The woman is under 40 at the start of the cycle — though women aged 40 and above can still access up to two of the six co-funded cycles if they've had ART before the age cap.
• A lifetime cap of three co-funded fresh and three co-funded frozen cycles.
• A doctor has assessed that you meet the clinical criteria for ART.

Because the age cutoff is a hard line and the ladder takes time, the practical takeaway is the same one fertility specialists give: if pregnancy is a goal, start the conversation earlier than feels necessary. The subsidy, the age caps, and the biology all reward not waiting.

Getting metabolically ready before you start

Here's where PMOS being a whole-body metabolic condition—not just an ovary problem—becomes an advantage you can act on. Insulin resistance is the hub that suppresses ovulation in many women, and it responds to the months before treatment starts.

Two levers with real evidence:

• Modest weight loss where relevant. In women carrying excess weight, losing even 5–10% can restore spontaneous ovulation and improve how well ovulation-induction works. (For lean PMOS, weight isn't the lever—the target is still insulin sensitivity, reached differently.)
• Myo-inositol. A Cochrane review of inositol in subfertile women with PCOS found improvements in ovulation and cycle regularity, with a strong safety profile—useful as adjunct support, not a replacement for medical care. The ratio matters more than the dose.

None of this is a substitute for seeing a fertility doctor. But the metabolic groundwork is the one part of the process you can start on your own, today, while referrals and appointments line up—and it's the part standard fertility clinics rarely have time to coach.

Where to start

Fertility care with PMOS is a ladder, not a leap—and in Singapore, one with meaningful public co-funding at the bottom of it. The move is to start the medical conversation early and use the waiting time to get metabolically ready.

Our free 5-minute assessment maps which drivers are behind your PMOS—insulin, androgens, ovulation, stress—and shows you a result without asking for anything in return. If you'd rather not self-source and guess at the metabolic-prep piece, Oestra turns that result into supplements matched to your drivers, shipped monthly and reviewed each month as things change. It's the day-to-day lifestyle layer alongside whatever fertility care you choose—not a fertility treatment, and never a replacement for one.

If your cycles are the deeper worry, our page on trying to conceive with PCOS goes into restoring ovulation itself.
