Urology is a surgical speciality that addresses male and female diseases of the urinary tract, as well as male reproductive system disorders. Urology is a part of health care that deals with diseases of the male and female urinary tract (kidneys, ureters, bladder and urethra). It also deals with the male organs that are able to make babies (penis, testes, scrotum, prostate, etc.). Since health problems in these body parts can happen to everyone, urologic health is important.
Male infertility refers to the inability of a male to make a fertile female pregnant. It is usually due to semen deficiencies. Infertility is a widespread issue. For about 20% of infertile couples, the problem is only in the male partner. For about 30% of couples, the problem is in both partners. Therefore, the man contributes to infertility in around half of all cases.
About one in 20 men have low numbers of sperm, causing infertility. However, only about one in every 100 men has no sperm at all.
