Infertility has become a widespread problem nowadays. One in five infertile couples, the problem lies solely in the male partner and in another quarter, both partners have problems. In most cases, there are no obvious symptoms or signs of infertility. Sexual activities like intercourse, erections and ejaculation will usually happen without difficulty and the quantity and appearance of the ejaculated semen generally appears normal to the naked eye.
Male infertility is usually caused by problems that affect either sperm production or sperm transport (blockage). Male Infertility may be due to- sperm production problems, blockage of sperm transport (obstruction), sexual problems (erection and ejaculatory problems), hormonal problems, and sperm antibodies. Initially, both partners should be tested around the same time as the problem could be in either the male or the female partner.
