Does gynecomastia cause infertility?

No, gynecomastia, which is the enlargement of breast tissue in males, does not directly cause infertility. At SCI Hospital, we explain that gynecomastia is usually due to an imbalance of hormones like estrogen and testosterone. While the underlying hormonal imbalance that leads to gynecomastia could in some cases be linked to other conditions that might also affect fertility (such as certain testicular or pituitary issues), the presence of enlarged breast tissue itself doesn't mean a man is infertile. A man with gynecomastia can still produce healthy sperm. If fertility is a concern, we would investigate the overall hormonal profile and testicular function.
