Can you get pregnant with PCOS? Yes — most women with PCOS do conceive, with or without treatment. Here is what helps and what to track.
PCOS is the most common cause of ovulatory infertility — but that does not mean you cannot get pregnant. Most women with PCOS do conceive, either naturally or with relatively straightforward treatment. Here is what the research actually says.
PCOS causes anovulation (lack of regular ovulation), which is the main barrier to conception. But anovulation is treatable. Studies show that with appropriate intervention:
The challenge with PCOS fertility is knowing when you're ovulating — because it's irregular and OPKs are less reliable for PCOS. The solution is tracking.
In PCOS, excess androgens (male hormones) and insulin resistance disrupt the normal follicle development process. Instead of one dominant follicle developing and releasing an egg, multiple small follicles develop but fail to fully mature. The result: either no ovulation, or ovulation at unpredictable times.
This is why PCOS cycles are often long and irregular — the follicle takes longer to mature, and ovulation, if it happens, may be delayed by weeks.
| Method | Reliability for PCOS | Notes |
|---|---|---|
| BBT charting | High — confirms ovulation | Temperature rise confirms ovulation occurred; not affected by PCOS hormones |
| Cervical mucus observation | Moderate | Can show fertile mucus without ovulation following (common in PCOS) |
| OPK (ovulation predictor kit) | Unreliable for PCOS | Elevated LH in PCOS causes multiple false positives |
| Ultrasound monitoring | High — gold standard | Available through fertility clinics; shows follicle development in real time |
| Progesterone blood test (day 21) | High | Elevated progesterone (>30 nmol/L) confirms ovulation occurred |
For women with PCOS and insulin resistance, lowering insulin levels — through diet, exercise, or metformin — improves ovulation frequency. A low-GI diet, reduced refined carbohydrates, and regular strength training are the most evidence-based lifestyle approaches.
A 5–10% reduction in body weight in women with PCOS and overweight has been shown to restore ovulation in up to 55–60% of cases. This works through reduced insulin, which lowers androgen levels and allows follicle development to proceed more normally.
Letrozole is the current first-line medication for PCOS-related infertility. It temporarily suppresses estrogen, which causes a surge in FSH, which stimulates follicle development. It has a higher live birth rate than clomifene (the older alternative) in PCOS.
Whether you're trying naturally or on medication, BBT charting gives you confirmation of ovulation. In natural cycles, this tells you which months you ovulated. On medication cycles, it confirms the treatment worked.
Start with your GP — ask for a referral to a gynaecologist or reproductive endocrinologist with PCOS experience. Bring your cycle charts.

Start tracking →Yes. Many women with PCOS conceive naturally without fertility treatment. The likelihood depends on whether you ovulate regularly and how well insulin resistance (if present) is managed. For women who don't ovulate regularly, medications like letrozole or clomifene can induce ovulation.
BBT charting is the most reliable at-home method — a temperature rise of 0.2–0.5°C confirms ovulation has occurred. Ovulation predictor kits (OPKs) can be unreliable for PCOS because elevated LH levels (common in PCOS) can give false positives.
Yes — for women with PCOS and insulin resistance, a 5–10% reduction in body weight has been shown to significantly improve ovulation frequency and fertility outcomes. This works because weight loss reduces insulin levels, which lowers androgen production, which allows the follicles to develop more normally.
The current first-line fertility treatment for PCOS is letrozole (an aromatase inhibitor), which has a higher live birth rate than clomifene in PCOS. Metformin is sometimes used alongside it, particularly for women with insulin resistance.
