Alternative medicine

Evidence is limited on whether — or how much — herbs or supplements might help increase male fertility. None of these supplements treats a specific underlying cause of infertility, such as a sperm duct defect or chromosomal disorder.

Supplements with studies showing possible benefits for improving sperm count or quality include:

• Coenzyme Q10
• Folic acid and zinc combination
• L-carnitine
• Selenium
• Vitamin C
• Vitamin E

Talk with your doctor before taking dietary supplements for male infertility. There is no clear evidence that they work, and some supplements may cause side effects or interact adversely with medications you take.
