Ductal and Structural Abnormalities
When a man experiences infertility, it is most often due to structural problems in his reproductive organs or damage to or blockage in one of his many tubes. Sperm needs to travel through several tubes or ducts before it is ejaculated out of the penis. If there are any blockages in one of these tubes, it can make pregnancy very difficult.
Tubes become blocked for a lot of reasons from scar tissue that develops after surgery to infections, which results in clogged tubes and thus, failing to ejaculate sperm. If you are suffering from ductal abnormalities, there are various surgeries that can help you unclog these blockages that are preventing you from getting pregnant. However, if there are too many blockages, it may be necessary to remove your sperm surgically and then be used in ICSI-assisted IVF.
Infertility can also be the result of structural abnormalities in a male's reproductive organs. Sometimes, there may be a part of a reproductive organ that may have not developed or formed properly and which the man may have been born with. So, it's important to know about the defects associated with the male reproductive system and how it can cause infertility. Below are a few congenital defects that occur in men.
CAVD, which stands for Congenital Absence of the Vas Deferens is a rare condition in which men are born without a vas deferens. Vas deferens is a channel, which transports the sperm from the testis to the seminal vesicle, so men born without a vas deferens will not be able to transport the sperm to join his semen. However, the man's testicles can produce sperm normally.
Hypospadias is a common problem among men. In this condition, the urethral opening is on the underside rather than the tip of the penis. Most often, the opening of the urethra is located by the head of the penis. But it can also be further down near the scrotum. Serious cases of hypospadias are most often treated with surgery while milder cases, which do not cause any infertility problems, are left alone.
Undescended testicles occur when testicles fail to descend from the abdomen to the scrotum during fetal development. This condition should be treated before the age of one or else it may result in infertility later in life.
