What are the causes of male infertility?
Hello, my friend is found to be infertile. He is in need of medical attention now. He got married five years back. His wife is not able to conceive after repeated times. What are the causes of male infertility? Please elaborate on this.
@sayantan Nearly 1 in 7 couples is infertile, which means they haven't been able to conceive a child even though they've had frequent, unprotected sexual intercourse for a year or longer. In up to half of these couples, male infertility plays at least a partial role. Male infertility can be caused by low sperm production, abnormal sperm function or blockages that prevent the delivery of sperm. Illnesses, injuries, chronic health problems, lifestyle choices and other factors may contribute to male infertility. In some cases, however, an underlying problem such as an inherited disorder, hormonal imbalance, dilated veins around the testicle or a condition that blocks the passage of sperm causes signs and symptoms.
