What are the common causes of semen?
The most common causes of sperm production in men include genetic defects that affect their fertility. Sometimes these defects can affect sperm production and at other times can lead to blockage that prevents sperm release. Other potential causes of small or no number of sperm may include injury to the testes or penis and vasectomy.
Clinefelter syndrome is the most common cause of sperm production. It is a genetic mutation in which the male has another sex chromosome. Most men have one X chromosome and one Y. Those with clinfelter syndrome have an extra chromosome X, leading to excessive breast production, small hard testes and infertility. There are also genetic defects that can change hormonal balance in men, and this can also lead to a lack of sperm production. Men who have problems with the child's father with their partners should be tested for these abnormalities.
Another genetic state that can lead to any spernature is the innate absence of van deferens (CAVD). ItIt results in a lack of pipes that are needed to secrete sperm into the semen. Sometimes a man can have a pipe, but are malformed. Males with this condition usually have average sperm production, but the sperm is trapped inside the testicles without ways to escape. Men with CAVDs can still impregnate a woman through artificial insemination, or in some cases, surgery may be performed to remove any blockage.
In some cases, one may have the absence of sperm for unknown reasons. Other times, penis or testicular injuries may lead to no sperm production. In these cases, some men may have correction procedures to repair damage. However, many times it cannot be done and the results of permanent infertility.
Men who had vasectomy will also have zero sperm. Sperm is still produced in Testiclus, but the passage between them and the penis is blocked or interiorabalone. In some cases, vasectomy may be reversed and full or partial fertility may be restored, but this is not always a possibility.
Even men with the number of zero sperm can have a small number of sperm in the testes. Modern infertility treatment can sometimes allow searching and using these sperm. Those who really have no sperm may have to resort to the use of sperm donor to have a family with their partners.
