Causes of Male Infertility
Transcript
Dr. Roger Lobo, of the American Society for Reproductive Medicine explains the causes of male infertility.
Hi I'm Dr. Roger Lobo with the American Society for Reproductive Medicine.
Today, we're talking about the causes of male infertility. Male infertility can be due to a variety of conditions. Some of these can be found and corrected while others cannot be corrected.
Most problems with male infertility occur when there are low numbers of sperm or abnormalities in their movement or shape. This can result from abnormalities in the production, transport, or delivery of sperm.
A varicocele is a common potentially correctable cause of male infertility. A varicocele is a collection of enlarged veins in the scrotum that can affect sperm production and its characteristics. Varicocele occurs in about 15% of all men and as many as 40% of those who are infertile. The tricky thing with that area is there are a lot of fertile men who are found with varicocele, so what do you do when you find a small one in an infertile male? This is when a male might first want to consult with a urologist before acting on taking care of a varicocele which sometimes might require surgery.
About 10 to 15% of men with low sperm counts have an abnormality in the Y chromosome which affects the development of sperm. Others may be born without critical parts of the sperm transport process, such as the vas deferens, which connect the testes to the male urethra.
Vasectomy is a common surgical cause of male infertility in men who have changed their minds about fertilization. But men who have had other surgery in or near the reproductive tract also can have problems. Injury to the nerve supply and/or obstructions in a transport system can affect sperm production.
For some men, fertility is affected by abnormal hormones, too. Too much estrogen and/or too little testosterone can negatively affect the development and maturation of sperm. Other hormones may be involved as well.
Temperature also plays a critical role. Sperm can only mature at temperatures lower than the core body temperature. This is why the testes normally lie in the scrotal sacs outside of the body. Heat exposure or conditions where the testes have not descended into the scrotum can affect sperm production.
Male infertility can also be due to infections, certain medical conditions, and exposure to toxins such as chemotherapy or radiation.
