Male Infertility and Sexual Dysfunction


    Male infertility is a man's inability to cause pregnancy in a fertile female, commonly due to deficiency of sperm cells in the semen. Sexual dysfunction, also called erectile dysfunction, is an inability to maintain an erection sufficient for sexual intercourse. Both conditions may be treatable through medication or hormone therapy.
