Ozempic and Pregnancy: Fertility Effects, Safety, and When to

GLP-1 medications have transformed obesity treatment — but what happens when patients want to get pregnant? Or discover they’re already pregnant while taking Ozempic or Wegovy? This guide covers everything you need to know about semaglutide, fertility, and pregnancy in 2026.

Is Ozempic Safe During Pregnancy?

No. Semaglutide is contraindicated during pregnancy. Animal studies showed adverse effects on fetal development at doses lower than those used in humans, including skeletal and visceral abnormalities. While human data is very limited (these drugs are new and pregnant patients were excluded from trials), the precautionary principle applies strongly here.

Novo Nordisk’s prescribing information for both Ozempic and Wegovy explicitly recommends discontinuing the medication at least 2 months before a planned pregnancy. This is because semaglutide has a half-life of approximately one week and takes about 5 weeks to be substantially cleared from the body — hence the 2-month buffer recommendation.

What If You Get Pregnant While Taking Ozempic?

Stop the medication immediately and contact your prescriber and OB/GYN. Do not be alarmed — inadvertent early pregnancy exposure is unlikely to cause harm in most cases, but the medication should not be continued once pregnancy is confirmed. You should also consider enrolling in the Novo Nordisk pregnancy registry (1-800-727-6500), which tracks outcomes in patients exposed to semaglutide during pregnancy to build the evidence base.

Can Ozempic Improve Fertility?

Indirectly, yes — particularly for women with PCOS or obesity-related infertility. Here’s how:

Mechanism	How It May Improve Fertility
Weight loss	Even 5–10% weight loss can restore ovulation in obese women
Insulin resistance reduction	Critical for PCOS-related anovulation; better insulin sensitivity restores cycles
Androgen reduction	Weight loss lowers testosterone in PCOS, improving hormonal environment
Menstrual regularity	Many PCOS patients report restored or more regular cycles on GLP-1 therapy

An important and underappreciated point: women who weren’t using contraception because they believed they were infertile due to PCOS or obesity may find their fertility restored on semaglutide. Unintended pregnancies have been reported in women who started GLP-1 medications without realizing their fertility had improved. If you’re sexually active and not planning a pregnancy, use contraception while on semaglutide.

GLP-1 Medications and IVF

Some fertility clinics have begun requiring or recommending weight loss before IVF, as obesity is associated with lower IVF success rates, higher miscarriage rates, and increased pregnancy complications. GLP-1 medications can help achieve the weight loss needed to improve IVF candidacy. However, the medications must be stopped well before egg retrieval and embryo transfer. Work with both your reproductive endocrinologist and GLP-1 prescriber to plan the timing carefully.

What About Breastfeeding?

Semaglutide should not be used while breastfeeding. It is unknown whether semaglutide is excreted in human breast milk, but animal data suggests it may be. Given the potential for adverse effects on the nursing infant and the availability of alternative approaches for postpartum weight management, breastfeeding is a contraindication for GLP-1 use.

Ozempic and Male Fertility

Limited data exists specifically on GLP-1 effects on male fertility. Animal studies did not show sperm toxicity, and no human trials have specifically assessed semen parameters. Some small studies have shown improvements in testosterone levels and sexual function in men with obesity and low T who lose weight on GLP-1 medications. Men planning to conceive do not need to discontinue semaglutide based on current evidence, though this area needs more research.

Timing: When to Stop Ozempic Before Trying to Conceive

Situation	Recommendation
Planning pregnancy	Stop semaglutide at least 2 months before trying to conceive
Starting IVF cycle	Discuss timing with fertility clinic; typically stop before stimulation begins
Discovered pregnancy while on drug	Stop immediately; contact prescriber and OB; consider pregnancy registry
Postpartum (not breastfeeding)	Can restart after delivery if not breastfeeding; discuss with prescriber
Breastfeeding	Do not use; wait until after weaning to resume

Frequently Asked Questions

Can you get pregnant on Ozempic?
Yes — and more easily than you might expect. Women with PCOS or obesity-related infertility may see restored ovulation and fertility on semaglutide. Use contraception if you’re not planning a pregnancy. The medication itself should be stopped at least 2 months before attempting conception.

Does Ozempic affect birth control effectiveness?
Oral contraceptives may be less reliably absorbed due to semaglutide’s effect on gastric emptying. The prescribing information for some oral contraceptives notes this interaction. Non-oral contraceptive methods (IUD, patch, ring, injections) are not affected and may be preferable while on GLP-1 medications.

How long after stopping Ozempic can I get pregnant?
Novo Nordisk recommends waiting at least 2 months after stopping semaglutide before attempting pregnancy. This allows sufficient time for the drug to clear from your system given its roughly 5-week elimination half-life.

Can Ozempic help with PCOS fertility?
Indirectly, yes. By improving insulin resistance and promoting weight loss, semaglutide can restore ovulation in PCOS patients. Several case series and observational studies document improved menstrual regularity and fertility markers in women with PCOS on GLP-1 therapy. However, it must be stopped before pregnancy is attempted.
