Causes of male infertility
Men as well as women participate in the increasing number of couples who have problems with natural conception. In order to determine male fertility, examinations are carried out as part of comprehensive reproductive health care of the couple.
Causes of infertility in men can be divided into three basic types. These are pre-testicular, testicular and post-testicular causes. In addition, male fertility is influenced by genetic and immunological factors.
This is a condition where infertility is caused by insufficient development of the male genital glands - testicles. This is due to a number of reasons, such as genetic variations, tight clothing, cycling, horse riding, etc.
In these cases, infertility is caused by inferior ejaculate in terms of the number of viable and motile sperm. Sperm can have a wrong shape, composition, etc., this is described as teratospermia. Lack of sperm is referred to as oligospermia. Complete absence of sperm in the ejaculate is called azoospermia.
There are many factors that can affect quality of the ejaculate. They may for example include previous infection of measles, malaria, testicular cancer, and other illnesses.
Testicular function is normal in men with post-testicular cause, but sperm does not get out of the body. This may be caused for instance by obstruction of vas deferens, absence of vas deferens, prostate inflammation, faulty urethral outlet, impotence etc.
This problem concerns both women and men who have some genetic defects or are their carriers. It often means that there may not be inability to get pregnant naturally, but extracorporeal fertilization is recommended in these cases to exclude the possibility of conception of a child with a genetic defect. In order to detect possible transmission of chromosomal defects, we offer the possibility of testing genetic compatibility of the couple with CarrierTest.
Infertility caused by immunological aspects can affect both men and women. As a result of certain immunological problems, immune system can attack sperm or ovarian tissue. Couples with immunological problems often deal with problems of conception or frequent miscarriages.
According to the results of individual examinations, the physician may recommend further diagnostic examinations such as immunological or genetic examinations, examination by andrologist, sexologist or other specialist.
This diagnosis is further recommended for the purpose of discovering and subsequently treating the cause of infertility.
