Ozempic (semaglutide) is a popular prescription medication designed to help manage type 2 diabetes and, in some cases, promote weight loss. Recently, there have been many sporadic reports of women falling pregnant when on Ozempic despite being on birth control or having previously experienced fertility difficulties or miscarriage.[1]

While a direct causal link is yet to be fully established, there are a few theories about why this might be happening, such as the effects of weight loss on hormonal balance or the way ozempic potentially interact with oral contraceptives.

This article delves into any potential side effects of ozempic and what the rise of ozempic babies could mean for women suffering from hormone-related infertility issues. It also explores the safety concerns and regulatory status of Ozempic, particularly in the context of pregnancy.

Understanding Ozempic and Its Uses

Ozempic, known generically as semaglutide, is a GLP-1 receptor agonist. This class of drugs works by imitating the function of a hormone in the body called GLP-1, interacting with its receptor in a similar fashion.

GLP-1, or glucagon-like peptide-1, regulates blood sugar levels[2]. When blood sugar levels rise, they stimulate the pancreas to produce insulin.

Ozempic takes advantage of this mechanism. It helps control blood sugar in people with type 2 diabetes by provoking insulin production similarly to natural GLP-1. It also slows the stomach emptying rate, which can help regulate the appetite and lead to weight loss.

The dual action it poses on blood sugar control and weight loss makes Ozempic a popular choice for managing type 2 diabetes. However, its impact on hormones and potential effects on fertility and pregnancy are areas of ongoing research and discussion.

The Ozempic and Pregnancy Connection

Platforms like TikTok have become outlets for women to share their experiences with "Ozempic babies.”[3] These personal stories have fueled widespread discussion, raising concerns about the medication's potential impact on reproductive health and the effectiveness of birth control methods.

For those with diabetes who use ozempic controlling blood glucose and insulin levels may improve fertility and outcomes during pregnancy. According to the CDC, pregnant women with diabetes are at a higher risk for miscarriage, birth defects, and several other pregnancy complications.[4]

Some believe that the weight loss associated with Ozempic use may improve fertility. Weight loss has been linked to improved fertility in some individuals, particularly those with conditions like polycystic ovary syndrome (PCOS), who also require close blood glucose monitoring and control.

However, this is a complex area of research, and the relationship between weight loss and fertility can vary significantly among individuals.

Other research suggests that ozempic and other GLP-1 receptor antagonists may influence the following aspects of fertility:

  • Impact on Hormones

While GLP-1 antagonists focus primarily on blood sugar regulation and weight control, they may indirectly influence ovarian function, potentially impacting ovulation and menstrual regularity.

Research shows that non-PCOS women with insulin resistance and hyperinsulinemia undergoing assisted reproduction displayed lower levels of female reproductive hormones, including estrogen, progesterone, luteinizing hormone, and follicle-stimulating hormone.[5]

One study reveals that insulin resistance can affect up to 95% of infertile women without PCOS who have ceased ovulating and just over 20% of those with infertility who are still ovulating.

Insulin resistance is also widespread in postmenopausal women, which hormone replacement therapy is known to correct.[6]

Most of the fertility research looking at GLP-1 receptor antagonists focuses on treating those with PCOS.[7] These studies show that it positively influences ovarian function in these women, as hyperinsulinemia is responsible for promoting excess androgen and worsening outcomes. These medications can also promote regular menstruation in women with PCOS who otherwise struggle.[8]

While there is limited evidence to suggest a causal link, GLP-1 receptor antagonists may help infertile women with obesity, hyperinsulinemia, and insulin resistance to improve their odds of falling pregnant and manage menopausal symptoms or postmenopausal challenges.

  • Weight Loss and Fertility

Weight loss can lead to positive changes in women with conditions like Polycystic Ovarian Syndrome (PCOS). PCOS often causes hormonal imbalances that make conceiving difficult. Ozempic-induced weight loss may inadvertently restore hormonal balance, improving fertility unexpectedly.

Obesity can contribute to an increased likelihood of fertility issues in many women[9]. According to some medical experts, obesity elevates bodily estrogens, which can lead to further hormonal imbalances and even culminate in reproductive problems. Ozempic may aid in hormonal regulation by inducing weight loss. Those with obesity often have higher than average insulin and blood glucose levels as well, to which ozempic may pose further benefits.

Ozempic may aid in inflammation control by combating obesity[10], indicating a possible alternative benefit for fertility and pregnancy outcomes.

Women with endometriosis or reproductive cancer who are commonly overweight may benefit from ozempic. Preliminary evidence shows that GLP-1 antagonists like ozempic may lower weight in these women, reduce inflammation levels (which are possibly blood glucose-related), and improve insulin resistance.[11] These factors may also improve these women's chances of a successful pregnancy.

  • Reduced Birth Control Effectiveness

Though research is limited, research suggests that GLP-1 antagonists might interfere with the absorption of oral contraceptives by slowing gastric emptying. This could occur due to the medication's influence on gastric emptying and digestive processes. If true, it could increase the risk of unintended pregnancies even with consistent birth control use.

The evidence is clear that tirzepatide (Mounjaro), a different GLP-1 antagonist[12], can lower the effectiveness of oral contraceptives, with warnings present on the package insert. Studies have failed to confirm the same effects for ozempic[13], although cases of unplanned pregnancy while on ozempic is on the rise.

Safety Concerns and Research: Does Ozempic Make You More Fertile?

Whether Ozempic can enhance fertility is a topic of ongoing debate. As explained above, there is a small body of promising research to back up the increasing numbers of successful ozempic births in women with reproductive problems.

Ozempic and other similar medications are likely to be more successful in improving fertility in reproductively challenged women who are overweight or who suffer from insulin imbalances.

However, it is important to note that the relationship between weight loss and fertility is a complex area of active research. Conclusions about whether it improves pregnancy outcomes for infertile women have yet to be confirmed. There is also no guarantee that all women will experience the same effects.

Due to a lack of research on the matter, it is not advisable to take ozempic to improve fertility and lower miscarriage risk. Those battling with diabetes, obesity, or other conditions of insulin resistance need to confer with their healthcare providers to assess whether they are suitable candidates for ozempic use.

Can You Take Ozempic While Pregnant?

Currently, the FDA does not officially approve using Ozempic during pregnancy. This is primarily due to a lack of sufficient human studies on the drug's safety during pregnancy. Animal studies suggest that pregnant women should be cautious against using ozempic, showing reproductive toxicity with the use of GLP-1 receptor agonists[14], including semaglutide, the active ingredient in Ozempic. Other animal-related findings show that it may elevate the risk of birth defects and can pass down to offspring through breast milk[15].

If you are using Ozempic and planning a pregnancy, or if you become pregnant while using the drug, it is crucial to stop taking it immediately and consult with your healthcare provider.

The safety of Ozempic during pregnancy is a topic of ongoing research. As a GLP-1 receptor agonist, the potential risks to a developing human fetus or expectant mother are not fully known.

The active ingredient in Ozempic, semaglutide, also has side effects that may influence outcomes or intensify pregnancy symptoms, including fatigue, dizziness, digestive issues, pain, and hair loss.

The FDA classifies Ozempic as a "Category C" drug for pregnancy. This means that while animal studies highlight that it can cause adverse fetal effects, there are no well-controlled studies conducted in humans. Therefore, pregnant women should avoid using the drug and seek guidance from a healthcare professional.

The Importance of Planning

Preconception care, ideally starting at least three months before trying to conceive, is crucial for optimizing the health of both mother and baby. This includes supplementation, disease management, and lifestyle modifications.

When it comes to family planning for women with insulin resistance, the use of Ozempic requires careful consideration. This is particularly true for individuals of childbearing potential who are using the medication for weight loss or diabetes management.

Alternative weight loss strategies that are helpful include regular exercise, optimizing nutrition, and building sustainable healthier habits that promote an ideal hormonal profile.[16]

Discussing family planning with a qualified healthcare practitioner before starting Ozempic is crucial.

For those planning a pregnancy, exploring alternative weight loss options may be prudent. This is especially relevant if there are concerns about the potential impact of Ozempic on fertility or pregnancy. Lifestyle changes, including a diabetic-friendly diet plan and regular exercise, can be effective strategies for weight management.

Here are a few reputable organizations offering comprehensive information on building healthy eating plans:

  • ChooseMyPlate (US)
  • British Dietetic Association (UK)
  • Dieticians of Canada

Emphasize finding enjoyable movement that becomes part of your routine:

  • NHS Fitness Guides (UK)
  • American Heart Association Exercise Recommendations

Doctors and dietitians can develop customized weight management plans considering individual health needs and pregnancy goals.

In some cases, other medications may be considered. However, it is important to discuss these options with a healthcare provider. They can offer guidance founded on individual health status, goals, and potential risks.

The Future of Ozempic and Pregnancy

While anecdotal reports of "Ozempic babies" have sparked concern, large-scale, controlled studies are essential in establishing conclusive evidence.

Ozempic, in the context of pregnancy, is a topic of ongoing research. Scientists are working to understand the full implications of this medication on fertility and pregnancy. This includes studying the drug's impact on hormones, its potential to reduce birth control effectiveness, and its safety during pregnancy.

More information will allow doctors to tailor their recommendations for women of reproductive age considering Ozempic, offering the best possible results for their health and family planning.


Navigating the complexities of Ozempic, fertility, and pregnancy requires a comprehensive understanding of the medication and its potential impacts. Healthcare providers need to remain updated on the latest research and guidelines to better inform patients about the potential risks and benefits.

The decision to use Ozempic should be made individually, considering the patient's specific circumstances and health needs. As we continue to learn more about Ozempic and its effects on fertility and pregnancy, it is essential to approach this issue with care, transparency, and a commitment to patient-centered care.
