PCOS and Fertility: How to Get Pregnant With Polycystic Ovary Syndrome
Yes, you can get pregnant with PCOS (polycystic ovary syndrome). PCOS mainly affects fertility by causing irregular or absent ovulation, and that's very treatable. Most people start with healthy lifestyle changes and letrozole, an oral pill that helps the ovaries release an egg. If that doesn't work, options include injectable medicines, IUI and IVF.
A lot of people with PCOS were told as teenagers, "You'll have trouble getting pregnant," and have carried that fear for years. The reality is more hopeful. The problem is usually timing, not ability: you can't conceive in a month you don't ovulate, and treatment is mostly about making ovulation happen on a schedule.
How PCOS affects fertility
PCOS is a common hormone condition. It's diagnosed when someone has at least two of these three features (the "Rotterdam criteria"), after other causes are ruled out:
- Irregular or absent ovulation, usually seen as irregular or missed periods
- Signs of high androgens (male-type hormones), such as acne, extra facial or body hair, or high testosterone on a blood test
- Polycystic-appearing ovaries on ultrasound, or in adults a high AMH level under the 2023 international guideline
With PCOS, ovulation may happen rarely or unpredictably, so you get fewer chances to conceive each year. Insulin resistance, common in PCOS, can make ovulation problems worse.
Before you start trying: a checklist
Ask your OB/GYN or primary care clinician about:
- Blood sugar screening. PCOS raises the risk of prediabetes and type 2 diabetes, which also affect pregnancy.
- Blood pressure and thyroid checks.
- A prenatal vitamin with folic acid, which the CDC recommends for anyone who could become pregnant.
- A medicine review. Some PCOS treatments, like spironolactone, should be stopped before pregnancy. Don't stop anything without talking to your clinician first.
- A semen analysis for your partner, if you have one. It's easy and avoids months of treating the wrong problem.
Lifestyle changes that help (without the guilt)
For people with PCOS who have overweight or obesity, losing even about 5% to 10% of body weight can restore ovulation in some cases and improve response to treatment. For someone who weighs 200 pounds, that's 10 to 20 pounds, not a total transformation. You don't need to reach an "ideal" weight to benefit.
Habits that help:
- Regular activity, like brisk walking most days
- Balanced meals with fiber, lean protein and fewer refined carbs
- Good sleep and stress management
- Not smoking and limiting alcohol
A common frustration is being told to "just lose weight" and sent home. Lifestyle changes help, but you don't have to wait for weight loss before starting fertility treatment, especially if you're 35 or older. It's fine to ask for both at once.
Fertility treatments for PCOS
| Treatment | How it works | Notes |
|---|---|---|
| Letrozole | Oral pill for 5 days that triggers ovulation | First-line for most people with PCOS |
| Clomiphene citrate | Oral pill for 5 days | Older option; letrozole is generally preferred |
| Metformin | Improves insulin sensitivity | May help, especially with insulin resistance; less effective alone than letrozole |
| Gonadotropins (injections) | Directly stimulate follicles | Requires close monitoring; higher risk of twins |
| Ovarian drilling (laparoscopy) | Surgery to reduce androgen-making tissue | Occasionally used when medicine fails |
| IVF | Eggs retrieved and fertilized in the lab | Used when other treatments fail or other factors exist |
Letrozole: what a cycle looks like
Letrozole is the recommended first-line ovulation medicine for PCOS in the 2023 international guideline. Studies have found higher live birth rates with letrozole than with clomiphene in people with PCOS.
If your periods are very far apart, your doctor may first give a short course of progestin to bring on a period. Then you take letrozole for five days early in the cycle. Your doctor may confirm ovulation with an ultrasound, a progesterone blood test about a week after expected ovulation, or ovulation tests. If you don't ovulate, the dose is usually adjusted the next cycle. Ask your doctor about the dose and timing for you.
Injectable medicines and IUI
If oral medicine doesn't lead to ovulation or pregnancy, low-dose injections may come next. Because people with PCOS have many follicles, they're more sensitive to these medicines. Close ultrasound monitoring lowers the risk of twins, triplets and ovarian hyperstimulation. Injections are often paired with IUI. See IUI vs IVF.
IVF with PCOS
IVF works well for many people with PCOS, who often produce a lot of eggs. The main concern is ovarian hyperstimulation syndrome (OHSS). Clinics lower this risk with specific medication protocols, a different trigger shot, and freezing all embryos for a later transfer. See the IVF process step by step. In New York, insured large-group plans must cover IVF, so check your plan type early.
How long does it take?
Everyone's different. Many people with PCOS who start ovulating on letrozole conceive within several treatment cycles. If you're ovulating on medicine but not pregnant after several cycles, your doctor will check other factors, like your fallopian tubes and sperm, and may suggest IUI or IVF.
Can you track ovulation at home with PCOS?
It's trickier. Ovulation strips detect LH, and some people with PCOS have high LH levels that cause confusing or repeated positives. Cervical mucus tracking and basal body temperature may help. See ovulation tracking for tips, and ask your doctor about monitoring.
Is pregnancy with PCOS higher risk?
PCOS is linked to a higher risk of gestational diabetes, high blood pressure disorders and preterm birth. Good preconception care and early prenatal care help. Your OB/GYN may test for diabetes earlier in pregnancy.
Some studies suggest a higher miscarriage risk with PCOS, though the reasons aren't fully understood and may relate to weight, insulin resistance or other factors. Most people with PCOS who conceive have healthy pregnancies. After two or more losses, ask about a full evaluation.
When to see a doctor
See a doctor as soon as you start trying if your periods are irregular, come more than about 35 days apart, or have stopped. You don't need to wait 12 months.
Also see a doctor if:
- You've taken ovulation medicine for several cycles without pregnancy
- You're 35 or older
- Your partner hasn't had a semen analysis yet
- You have symptoms of high blood sugar, like excessive thirst or urination
Many OB/GYNs can start letrozole and basic testing. A reproductive endocrinologist is a good next step if first-line treatment doesn't work or you need injections or IVF. Find fertility specialists across New York, including Brooklyn and Manhattan.
Frequently asked questions
Can you get pregnant with PCOS?
Yes. PCOS is one of the most treatable causes of infertility. Many people with PCOS conceive naturally or with ovulation medicine, and IVF is available if simpler treatments don't work.
What is the first-line fertility treatment for PCOS?
Current international PCOS guidelines and ASRM recommend letrozole as the first-line medicine to induce ovulation for most people with PCOS who are trying to conceive.
Does losing weight help with PCOS fertility?
For people with PCOS who have overweight or obesity, losing even a modest amount of weight, often around 5% to 10% of body weight, can improve ovulation and the chance of pregnancy.
How long should I try to conceive with PCOS before seeing a doctor?
You don't need to wait a full year. If your periods are irregular or absent, it's reasonable to see a doctor as soon as you start trying.
