In 40% of the causes of infertility in the couple are due to problems in the man. There is nothing wrong or shameful about men to have some tests, if pregnancy does not happen immediately and they cannot have their desired child. On the contrary, the support of the male partner in this case is absolutely necessary. When a couple suffers from infertility, both partners should be tested so that the causes of their infertility to be determined. The reasons that cause problems in male reproductive system, and subsequently male infertility, are most diverse, and in many cases, a combination of several factors.

The reasons for infertility may be severe stress, exposure to heat, work in a hot environment, frequently taking hot baths and saunas, long hours in a sitting position or driving, inappropriate choice of underwear made of synthetic fabrics, wearing tight pants, long hours using a laptop on their thighs and when sitting or lying down. Excessive use and abuse of alcohol, tobacco, drugs, anabolic steroids and other substances can also cause infertility.

As men get older the quality and mobility of their sperm decreases, but this is not a general rule.

Change in the normal levels of key hormones for the spermatogenesis/sperm production/: The reasons for infertility can be caused by a change in the normal levels of testosterone, LH, FSH, prolactin, estradiol, inhibin B and other hormones that play an important role in the formation and maturation of the sperm.

If there is a hormonal imbalance and highly degraded sperm parameters, a consultation with an endocrinologist is necessary.

IMMUNOLOGICAL FACTOR or the presence of anti-sperm bodies:

In many cases (5-7%) presence of anti-sperm antibodies is determined in a man’s ejaculate. Normally, sperm is separated from the immune system through a barrier: blood-testicle. Upon contact of the sperm with the immune system are formed antisperm antibodies.

This condition may be a result from some post-surgery damage or a vasectomy (interruption of the vas deferens), infectious diseases, cryptorchidism (condition in which one or both testicles have not taken in time their normal position), varicocele (enlargement of the veins in the testicles) and other reasons.

The presence of anti-sperm antibodies often prevents the sperm cells from reaching the egg, or if they reach it – it makes the insemination impossible to happen.

GENETIC FACTORS: Genetic factors, such as deletions in the Y-chromosome or a different number from the normal number of chromosomes may also cause infertility in men.

When a genetic problem has been medically determined, pre-implantation diagnostics may be applied in order embryos that do not carry genetic defects to be selected, and subsequently, to be used for an embryo transfer.

Infertility in men is often caused by ANATOMICAL PROBLEMS.

An example of such a problem is the retrograde ejaculation: a condition in which the ejaculate falls into the bladder instead normally pass through the ureter.The reasons for the retrograde ejaculation may be: prostate problems, birth defects, bladder surgery and other reasons.

Anatomical problems are also associated with the condition, called varicocele. This is an abnormal enlargement of the veins in the testicles. In most cases, varicocele leads to decreased fertility in men, but it can be overcome with surgical treatment after a consultation with an andrologist.

The erection dysfunction in some cases is also an obstacle for achieving pregnancy. It is expressed in a man’s inability to achieve a normal erection. The reasons for this condition may be alcohol abuse, diabetes, antidepressants, low levels of testosterone and other reasons.
