What is the impact of extreme obesity on male fertility?

• A. It improves penile penetration efficiency
• B. It has no effect on fertility
• C. It may interfere with effective penetration and deposition
• D. It increases sperm production

Answer: (C)

Extreme obesity can impair male fertility by affecting sexual function and the delivery of sperm during intercourse. Excess body fat often contributes to erectile dysfunction through vascular and hormonal changes (such as lower testosterone and higher estrogen from adipose tissue) and can also introduce psychological factors, all of which make achieving and maintaining an erection for penetration more difficult. In addition, excess abdominal and scrotal fat can physically hinder penetration and the proper deposition of semen. Because fertility relies on successful intercourse and sperm deposition, this functional barrier reduces fertility potential. The other options don’t fit because extreme obesity does not improve penetration, is not without effect, and is not known to increase sperm production; in fact, it can negatively impact hormonal balance and semen quality.
