Question

Quizplus · Accepted Answer

The most common cause of male infertility is having too few sperm, which can be caused by a variety of factors such as hormonal imbalances, genetic defects, infections, and lifestyle choices such as smoking or excessive alcohol consumption. Incompatibility with partner or differences in sexual behavior may affect a couple's ability to conceive but are not considered the primary cause of male infertility. Excessive birth control does not affect male fertility as it is a method used by females to prevent pregnancy.
