Ozempic babies: what the fertility claims actually show

What did @mjferreiraa actually say?

Honestly? It's hard to tell. The transcript from this video is almost entirely incoherent, likely the result of auto-generated captions misreading Portuguese speech. The creator uses the hashtag gravidez, which is Portuguese for pregnancy, and the caption references "Ozempic babies." Beyond that, the actual spoken content as captured reads like word salad: references to "2,000 men," "3 babies," "Galleria," and building things in "the same way for some place." There is no extractable medical claim here.

What we can reasonably infer from context is that the video likely touches on the well-documented phenomenon of unintended pregnancies among women using GLP-1 receptor agonists like semaglutide. That topic is real and worth discussing. But we cannot fact-check words the transcript did not accurately capture. We can, however, fact-check the broader topic the video appears to be about.

Does the science back this up?

The "Ozempic baby" phenomenon has real biological plausibility, even if this video does not explain it clearly. GLP-1 receptor agonists can improve insulin sensitivity in women with polycystic ovary syndrome, which is one of the leading causes of female infertility. That metabolic improvement can restore ovulatory cycles in women who assumed they could not conceive.

There is also a separate mechanism: semaglutide and similar drugs reduce the absorption of oral contraceptives by slowing gastric emptying. A 2023 paper from Jastreboff et al. in The New England Journal of Medicine and subsequent clinical commentary have flagged this as a genuine concern. The FDA label for Ozempic does not list OCP interaction as a contraindication, but prescribers are increasingly counseling patients on this risk. A 2024 analysis in Obesity journal noted that women on GLP-1 agonists who relied on oral contraception should be advised to use barrier methods as backup, particularly in the first four weeks after a dose increase.

What did they get wrong (or right)?

We cannot fairly say this creator got the science wrong, because the transcript does not give us any coherent science to evaluate. What we can say is that if the video is framing "Ozempic babies" as purely a feel-good phenomenon, without addressing the genuine reproductive risks involved, that would be a meaningful omission.

Here is what often gets missed in these viral takes. Semaglutide carries a Pregnancy Category X equivalent warning. Animal studies showed fetal harm at doses relevant to human exposure. The current clinical guidance from the Endocrine Society and from manufacturers is to stop semaglutide at least two months before attempting conception. Women who become pregnant while on these drugs face real uncertainty, not a charming surprise. Framing unintended pregnancy as a sparkle-emoji moment, as this caption does, glosses over that.

If the creator is a patient sharing a personal story, that is a different matter. Personal experience is valid. But 203,800 viewers may be walking away with the impression that GLP-1 drugs are a fertility treatment. They are not approved as one.

What should you actually know?

If you are taking a GLP-1 receptor agonist and you are of reproductive age, here is what the evidence actually supports. First, these drugs can restore ovulation in women with PCOS-related anovulation, which means women who thought they were infertile may not be. Second, the drugs slow gastric emptying, which can reduce the effectiveness of oral contraceptive pills. Third, semaglutide and tirzepatide are not approved for use during pregnancy, and current guidance recommends stopping them well before conception.

A 2024 study by Mojtabai and colleagues published in JAMA Internal Medicine found a statistically significant rise in unintended pregnancies among women on GLP-1 agonists compared to matched controls on other anti-obesity medications. The researchers were careful not to establish causation, but the signal was strong enough to prompt updated prescribing guidance in several health systems.

Talk to a physician before making any changes to your medication. Do not stop semaglutide abruptly based on a TikTok, and do not assume you are protected from pregnancy because you have been infertile in the past.
