Does Wegovy Affect Fertility in Men?

Linda Girgis | MD

Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 21st, 2026.

Wegovy (semaglutide) may affect male fertility through weight-related improvements rather than direct hormonal interference. Obesity significantly impacts male fertility by reducing testosterone levels, decreasing sperm quality, and causing erectile dysfunction. Studies show that men with BMI over 30 have 20% lower testosterone and reduced sperm concentration compared to normal-weight men. As Wegovy helps achieve substantial weight loss (average 15-17% body weight in clinical trials), many men experience improved hormonal balance and fertility markers. However, no large-scale studies have specifically examined Wegovy's direct effects on male reproductive function. If you're planning to start a family while using Wegovy, we can help you understand how weight loss medications might impact your fertility goals.
