GLP-1 drugs and pregnancy: what the evidence actually shows

What did @anastasiamalhotra actually say?

Anastasia, now 13 weeks pregnant, credits semaglutide (Ozempic) with getting her pregnant after five years of marriage with no positive pregnancy tests. She says "Ozempic got me pregnant" because her periods became regular and her energy improved while on it. She also notes she stopped Ozempic in November before becoming pregnant in early December, and correctly flags that using it during pregnancy "is really dangerous." She was previously on Wegovy, which was discontinued by her doctor due to gallbladder problems, then switched to Ozempic, which was later stopped because she is neither pre-diabetic nor diabetic.

Her core claim is this: GLP-1 receptor agonists like semaglutide may have improved her hormonal environment enough to support conception. She adds, "I really think there should do a study on this," pointing to what she sees as a broader pattern among women online claiming their pregnancies followed GLP-1 use.

Does the science back this up?

There is genuine biological plausibility here, but "Ozempic baby" is not yet an evidence-based clinical concept. The connection between GLP-1 receptor agonists, hormonal regulation, and fertility is early and largely indirect. Here is what the research actually shows.

Women with obesity and polycystic ovary syndrome (PCOS) have long-established links between insulin resistance, elevated androgens, irregular ovulation, and reduced fertility. Weight loss itself, through any mechanism, can restore ovulatory cycles. A 2023 review in Frontiers in Endocrinology (Peng et al.) noted that GLP-1 receptors are expressed in ovarian tissue and the hypothalamus, suggesting these drugs could influence reproductive hormone signaling beyond just weight loss. A separate small study in Reproductive BioMedicine Online (2023, Salamun et al.) found improved menstrual regularity in women with PCOS treated with semaglutide.

That is meaningful. But none of this proves causality, and Anastasia herself stopped the drug before conception, which complicates any direct attribution. Weight loss from the drug, improved insulin sensitivity, or restored ovulation could all be factors, none of which require the drug to still be present at conception.

What did they get wrong (or right)?

She got the safety warning right. Semaglutide and tirzepatide carry an FDA warning against use during pregnancy, and animal studies have shown fetal harm at clinically relevant doses (FDA label, Ozempic, 2023). Stopping the drug before a known pregnancy is the correct call. She is not wrong to be relieved about the timing.

Where her framing gets shaky is the causal story. "Ozempic got me pregnant" is a compelling narrative, but it is exactly that, a narrative. Five years of unprotected sex with no pregnancy followed by conception shortly after stopping a GLP-1 drug is suggestive, not proof. She did not mention being evaluated for PCOS, insulin resistance, or other fertility-related conditions, which would have added clinical weight to her account. The gallbladder issue with Wegovy is consistent with known adverse effects: GLP-1 drugs reduce gallbladder motility and increase cholelithiasis risk (Nauck et al., 2021, New England Journal of Medicine).

She is also right that this deserves a proper study. The anecdotal pattern is real enough that researchers should be looking at this systematically.

What should you actually know?

If you are using a GLP-1 drug and are sexually active, pregnancy is a real possibility to plan around, particularly if your cycles have become more regular on the medication. The American College of Obstetricians and Gynecologists recommends stopping GLP-1 receptor agonists at least two months before a planned pregnancy, given drug half-lives and the absence of safety data in human pregnancies.

Women should not interpret this video as evidence that Ozempic or Wegovy is a fertility treatment. There are no approved GLP-1 drugs for fertility indications. What the evidence does support is that weight loss and improved insulin sensitivity, which these drugs can produce, are associated with improved ovulatory function in women with obesity or PCOS. The drug may be the vehicle, not the mechanism.

• Use reliable contraception if you are on a GLP-1 drug and not trying to conceive.
• If you are trying to conceive, talk to your prescribing doctor about timing and discontinuation windows.
• Do not self-discontinue a GLP-1 drug without medical guidance, even if you suspect pregnancy.

Bottom line

Anastasia's story is biologically plausible and her safety instincts are sound. But "Ozempic got me pregnant" deserves a study, not a TikTok caption, before it becomes conventional wisdom. The mechanism likely involves improved hormonal and metabolic conditions rather than some direct fertility effect of the drug itself. Her call for research is, genuinely, the right one.
