“Ozempic Babies”: Do Weight-Loss Drugs Impact Fertility and Are They Safe?


For Catera Bentley, the discovery of her pregnancy was nothing short of miraculous. After struggling with infertility due to polycystic ovary syndrome (PCOS), she had almost given up hope of conceiving. However, her journey took an unexpected turn when she started taking Mounjaro, a medication primarily prescribed for weight loss.

Bentley’s experience is not an isolated case. Many women, like her, have shared similar stories of unexpected pregnancies while on GLP-1 drugs, often referred to as “Ozempic babies” in social media circles. These medications, which include Ozempic, Mounjaro, and Wegovy, are part of a class known as GLP-1 receptor agonists. Originally approved for managing type 2 diabetes, they have gained popularity for their potential to aid weight loss.

The success of GLP-1 drugs in promoting weight loss has raised questions about their impact on fertility and pregnancy. While weight loss itself can enhance fertility by restoring normal ovulation patterns, GLP-1 drugs may further amplify this effect. By improving insulin regulation and reducing appetite, these medications offer hope for individuals struggling with infertility due to conditions like PCOS.

However, concerns persist regarding the safety of GLP-1 drugs during pregnancy. Limited data exists on the potential risks posed to fetuses exposed to these medications in utero. Both Novo Nordisk and Eli Lilly, the manufacturers of Wegovy and Mounjaro respectively, excluded pregnant individuals from their clinical trials, leaving a gap in understanding the drugs’ effects on pregnancy outcomes.

Despite the lack of comprehensive studies, anecdotal evidence suggests that pregnancies while on GLP-1 drugs have generally resulted in favorable outcomes. However, caution is warranted, as animal studies have hinted at potential risks, including low birth weight and developmental abnormalities, associated with high doses of these medications.

Furthermore, the use of GLP-1 drugs in early pregnancy raises questions about their impact on fetal development. While weight loss can be beneficial, sudden discontinuation of these medications during pregnancy may lead to rapid weight regain, posing additional challenges for expectant mothers.

In the absence of definitive safety data, healthcare providers face a dilemma when prescribing GLP-1 drugs to women of childbearing age. The prescribing information for these medications advises against their use during pregnancy, emphasizing the importance of contraception for individuals of reproductive age.

Despite the uncertainties, ongoing research seeks to shed light on the complex relationship between GLP-1 drugs, fertility, and pregnancy. Clinical trials exploring the efficacy of these medications in conditions like PCOS offer hope for a better understanding of their reproductive effects.

For women like Bentley, navigating the decision to continue or discontinue GLP-1 drugs during pregnancy is fraught with anxiety. While her daughter, Ivy, was born healthy, Bentley’s experience underscores the need for more comprehensive research to guide healthcare decisions for women of reproductive age.

In the meantime, healthcare providers and patients alike must weigh the potential benefits of GLP-1 drugs against their unknown risks, emphasizing open communication and informed decision-making in managing reproductive health concerns. As research advances, a clearer understanding of the role of GLP-1 drugs in fertility and pregnancy will hopefully emerge, offering guidance for individuals navigating the complexities of reproductive healthcare.
