Approximately 15 percent of couples are infertile. This means they aren't able to conceive a child even though they've had frequent, unprotected sexual intercourse for a year or longer. In about half of these couples, male infertility plays a role.
Male infertility is due to low sperm production, abnormal sperm function or blockages that prevent the delivery of sperm. Illnesses, injuries, chronic health problems, lifestyle choices and other factors can play a role in causing male infertility.
There are various methods to treat the male infertility factors such as IUI, IVF, ICSI, Donor sperms etc. Most of the male infertility issues can be treated by using conventional methods such as taking medications which helps to increase sperms.
