What Is Male Infertility

Male infertility refers to failure of a man to achieve pregnancy in a fertile female. Male infertility accounts for one in five infertile couples. In human beings male infertility accounts for 40 to 50% of infertility. One of the most accepted and widely defined reasons of male infertility is low sperm count and semen quality is used as a surrogate measure of male fecundity.
Male infertility can be diagnosed by semen analysis. Semen analysis involves lab testing of semen for diagnosis of the quality of sperm, amount of sperm, shape of sperm and movement of sperm. In most case male infertility is not recognized. Intercourse, erections and ejaculation usually happen without difficulty. The quantity and amount of ejaculated semen generally appears normal to the naked eyes.
