Exploring the Unintended Link Between GLP-1 Agonists and Pregnancy

by Ella

The use of popular anti-obesity and diabetes drugs, such as Wegovy and Ozempic, has been associated with an unexpected phenomenon: unplanned pregnancies, even among women who have struggled with fertility issues. As reports of this occurrence continue to emerge, healthcare professionals are grappling with the implications and seeking to understand the potential impact of GLP-1 agonists on fertility.


Key Insights:

Off-Label Use: Some doctors have been prescribing GLP-1 agonists off-label to women with polycystic ovary syndrome (PCOS), a hormonal disorder often linked to infertility. The rationale behind this practice is the potential for weight loss induced by these drugs to correct hormonal imbalances in PCOS patients.


Weight Loss and Fertility: Weight loss is known to positively influence fertility, and it’s speculated that the significant weight loss achieved with GLP-1 agonists may be a contributing factor to the reported increase in unplanned pregnancies.
Hormonal Interactions: There are concerns that GLP-1 agonists might affect the efficacy of birth control pills, potentially reducing their effectiveness. Limited data suggests that some GLP-1s may interfere with hormonal contraceptives, prompting caution among healthcare providers.


Safety Considerations: The safety profile of GLP-1 agonists in pregnant women is not well-established, as pregnant individuals were typically excluded from clinical trials. Drug manufacturers are now conducting studies to assess the impact of these medications on pregnancy outcomes.


Clinical Recommendations: Healthcare professionals are advising patients to consider alternative contraception methods, such as long-acting reversible contraceptives (LARCs) like intrauterine devices (IUDs), which are not believed to be affected by GLP-1 agonists.

Implications and Future Research:

The unintended association between GLP-1 agonists and unplanned pregnancies underscores the need for further research to elucidate the mechanisms underlying this phenomenon.

Clinicians should exercise caution when prescribing GLP-1 agonists to women of childbearing age, particularly those with PCOS or fertility concerns.

Continued monitoring and data collection are essential to assess the safety and efficacy of GLP-1 agonists in pregnant individuals and their offspring.


As GLP-1 agonists gain popularity in the treatment of obesity and diabetes, it’s crucial to remain vigilant about potential side effects, including their impact on fertility and pregnancy. By fostering collaboration between healthcare providers, researchers, and regulatory agencies, we can ensure that patients receive evidence-based care and minimize risks associated with medication use.
