Mounjaro
Many women taking Mounjaro (tirzepatide) for weight management or PCOS also ask: Can it affect my fertility?
Mounjaro isn’t licensed as a fertility treatment, but by improving insulin sensitivity, hormone balance, and weight regulation, it may indirectly support better reproductive health for some women.
This guide explains what the research shows — and what to consider if you’re trying to conceive while taking Mounjaro.
How Weight and Hormones Affect Fertility
Being significantly overweight or underweight can disrupt the hormones that control ovulation.
For women with PCOS, excess insulin and androgens often prevent eggs from maturing properly, causing irregular cycles or anovulation (no ovulation).
Losing even 5–10% of body weight can improve ovulation rates and restore menstrual regularity.
That’s where medicines like Mounjaro may help, under medical supervision.
How Mounjaro Works
Mounjaro mimics two natural hormones — GLP-1 and GIP — which:
- Regulate blood-sugar levels and insulin sensitivity
- Reduce appetite and cravings
- Slow digestion, helping you feel full longer
These actions can help women with PCOS or insulin resistance achieve gradual, sustainable weight loss — which, in turn, may support normal hormone function and fertility.
Can Mounjaro Improve Fertility?
Early evidence and clinical experience suggest that:
- Weight reduction through Mounjaro can restore ovulation in women with PCOS.
- Improved insulin balance may reduce androgen levels (linked to acne and irregular periods).
- Some women experience more predictable cycles within a few months of treatment.
However, Mounjaro is not approved as a fertility medicine, and its effects on pregnancy are still being studied.
Important: Do Not Use Mounjaro During Pregnancy
If you become pregnant while taking Mounjaro, you must stop the injections immediately and contact your prescriber.
Tirzepatide should not be used during pregnancy or while planning to conceive because its effects on the developing baby are unknown.
It’s recommended to stop Mounjaro at least one month before trying to get pregnant, to allow the medicine to fully leave your system.
If You’re Planning a Pregnancy
- Speak with your prescriber before you start trying to conceive.
- Focus on nutrition — balanced, whole-food diet with plenty of protein and fibre.
- Exercise moderately — 30 minutes daily can support hormonal balance.
- Take folic acid (400 mcg daily) before conception.
- Track your cycles — use an app or ovulation test kits.
Your prescriber may suggest transitioning off Mounjaro to other PCOS or pre-pregnancy management options once a healthy weight is achieved.
