🛡️ SOVAL Fact Check: Do GLP-1 Drugs Like Ozempic Boost Male Fertility?VERDICT: Contested (Credible sources genuinely disagree)
Checked July 24, 2026 · We'll re-check as this develops
Current evidence suggests GLP-1 drugs are unlikely to harm male fertility and may modestly improve markers like testosterone and sperm count—especially in men with obesity. However, data is limited, and credible experts disagree on whether these drugs actually "boost" fertility directly or if the improvements are simply a byproduct of weight loss.

The internet has been buzzing with stories of unexpected pregnancies linked to GLP-1 receptor agonists like Ozempic and Wegovy. While the focus has largely been on women, a new narrative is rapidly gaining traction: can these blockbuster weight-loss drugs act as a fertility treatment for men?
Men seeking to improve their reproductive health are increasingly asking their doctors if semaglutide can boost their testosterone and improve their sperm count. We analyzed 17 credible sources, ranging from peer-reviewed medical journals to institutional health sites, to find the truth.
The verdict? The claim is heavily contested. While the drugs show promise, the medical community is divided on how to interpret the results.
The Majority View: A Metabolic Byproduct, Not a Magic Shot
Most high-quality reviews and expert commentary agree on one reassuring fact: taking GLP-1 drugs is unlikely to harm male fertility.
Furthermore, current evidence suggests these medications can modestly improve male fertility markers, specifically for men suffering from obesity or metabolic dysfunction. But here is where the nuance is critical: the majority of experts do not believe the drug itself is directly boosting fertility.
Instead, the benefits are indirect. Obesity is a known driver of low testosterone and poor sperm quality. When GLP-1 medications help a man lose a significant amount of weight, his metabolic health improves, inflammation drops, and his hormone balance naturally restores itself. Because of this, mainstream experts argue that these drugs should not be prescribed simply as a general "fertility booster" for men of a normal weight.
The Credible Dissent: Direct Benefits vs. Unknown Risks
While the majority view preaches caution, there is credible dissent pushing the narrative further.
The Optimistic View: Certain clinicians, institutional health sites, and recent clinical presentations point to data indicating that GLP-1 treatments may improve reproductive hormones and sperm parameters across the board. Some small studies suggest that these drugs could serve as a better alternative to traditional testosterone replacement therapy, which can actually suppress sperm production.
The Skeptical View: On the flip side, some retrospective studies show that the drugs have a minimal effect, producing only modest sperm count changes without consistently improving sperm motility (movement) or volume.
There are also clinical warnings that rapid weight loss—whether from surgery or GLP-1s—can temporarily signal to the male body that conditions are not ideal for reproduction, potentially reducing sperm quality in the short term.
The 2026 Takeaway
If you are a man dealing with obesity-related low testosterone, the current data suggests GLP-1 drugs might help restore your natural hormone levels as you lose weight. However, claiming that Ozempic is a reliable, universal "fertility booster" for the general male population outpaces the current science.
