How Do GLP-1 Medications Affect Fertility?

GLP-1 medications like Ozempic® and Wegovy® are getting a lot of attention for weight loss. These medications, originally used for Type 2 diabetes, are now commonly prescribed for weight loss as well. They work by reducing appetite, improving blood sugar control and supporting insulin sensitivity.

Let’s walk through how excess body weight and GLP-1s can affect fertility, as well as the medication’s effect on pregnancy.

How Weight and Fertility Connect

Body weight can influence fertility, especially when insulin resistance or conditions like PCOS are involved. Higher levels of body fat can disrupt hormones, affect ovulation and increase inflammation. The good news is that even modest weight loss, around 5% to 10% of body weight, can improve ovulation and pregnancy rates for many people.

Do GLP-1 Medications Affect Fertility?

Early research suggests GLP-1 medications may indirectly support fertility for certain patients by improving insulin sensitivity, lowering androgen levels and reducing inflammation. For some people, especially those with insulin resistance, these effects may lead to more regular menstrual cycles and improved hormone balance.

That said, they’re not right for everyone. GLP-1 medications are not fertility treatments, and timing matters. Any decision to use them should always be made with guidance from a qualified healthcare provider.

Important Safety Note: GLP-1 Use During Pregnancy

GLP-1 medications are not recommended during pregnancy. Current guidance suggests stopping them at least two months before trying to conceive.

Why? Appetite suppression can make it harder to meet calorie and nutrient needs, side effects like nausea or gastrointestinal discomfort are common, and certain medical histories can make these medications unsafe.

Any decision about using GLP-1 medications should always be made with your healthcare team, especially if pregnancy is part of your plan.

The Bottom Line

GLP-1 medications can be a helpful tool for some people navigating weight and fertility, but they’re not a one-size-fits-all solution.

The right timing, enough nourishment and individualized care make all the difference. If you’re considering these medications or already using them, have an open conversation with your fertility care team. Together, you can create a plan that supports your health now and your future pregnancy goals.

GLP-1 and Fertility: Common Questions

Can Ozempic or Wegovy improve fertility?

GLP-1 medications are not fertility treatments, but by improving insulin resistance and supporting weight loss, they may help restore ovulation in some individuals.

Can you take GLP-1 medications while trying to conceive?

Most medical guidelines recommend stopping GLP-1 medications at least two months before trying to conceive.

Can you take GLP-1 medications during pregnancy?

No. GLP-1 medications are not recommended during pregnancy.

Are GLP-1 medications safe for people with PCOS?

Some research suggests GLP-1 medications may help people with PCOS by improving insulin resistance and metabolic health, but they should only be used under medical supervision.
