Male infertility

Male fertility, to a great extent, depends on the sperm’s functional quality.
As a result of an unhealthy lifestyle, some men may encounter difficulties with a low sperm count motility or shape problems and, therefore, functional deterioration. Such sperm can then lose the ability to penetrate the cervix, travel through the uterus and fertilize the female egg.
Impaired semen analysis results can be also caused by genetic problems, hormone production disorders, autoimmune diseases (anti-sperm antibodies) or an obstruction in the urinary tract of the male reproductive system.
Ejaculation disorders are ranked among causes of male infertility.  It is a condition in which  ejaculation does not occur at all, or it occurs in a form of so-called retrograde ejaculation(ejaculation into the urinary bladder).
Sometimes a man can suffer from anatomical problems, such as an enlargement of the veins in the scrotum (varicocele). In such cases, the testicular temperature increases and it can influence the sperm production. Furthermore, inflammatory diseases (chlamydia, trichomonas, ureaplasma, mycoplasma, etc.) have a great impact on the sperm quality.
However, in many cases the causes of infertility may not be detected (it is called the idiopathic factor).
