Frequently Asked Questions
›What lifestyle factors affect male fertility?
Smoking, excessive alcohol, heat exposure to the testes (laptops, hot baths, tight underwear), obesity, anabolic steroid use, and high psychological stress all negatively impact sperm production and quality.
›Can diet improve sperm quality?
A Mediterranean-style diet rich in antioxidants (vitamin C, E, zinc, selenium, coenzyme Q10) is associated with better semen parameters. Ultra-processed food, trans fats, and excessive soy intake may negatively affect sperm quality.
›When should a man get a semen analysis?
If a couple has been trying to conceive for 12 months without success (or 6 months if the female partner is over 35), both partners should be evaluated. Semen analysis is inexpensive, non-invasive, and provides valuable baseline data.
