Some people think that infertility mostly happens in women and very seldom in men. This is not true. In fact, studies show that in a couple facing infertility, 30% is caused by men and 30% is caused by women. This means there are times infertility doesn’t choose a gender. Here’s a few of the many possible causes of male infertility.
Hormonal problems such as pituitary tumors and steroid abuse may cause infertility in men. About two-thirds of infertile men have a problem with making sperm in the testes. Either low numbers of sperm are made and/or the sperm that are made do not work properly.
Sperm production problems
Varicocele (or varicose veins of the testes), medicines and chemicals and radiation damage all contribute to the male fertility fuctions. Men having these issues are candidates for infertility.
A man’s fertility mostly rely upon his sperm count, sperm motility and sperm morphology. Low sperm count happens if a man has fewer than 15 million sperm per milliliter of semen. Sperm motility talks about the sperms’ movements. Sperm morphology, on the other hand, is about the size and shape of the sperm. A normal sperm has an oval head with a long tail. Any sperm that does not have an oval head and a long tail can be considered abnormal sperm.
In most cases, there are no obvious signs of infertility in men. Erections, intercourse and ejaculation still happen without difficulty. In order to determine if a man has infertility problems, medical tests need to be conducted.
