Main causes in men

Sperm alterations

It refers to the altered motility of spermatozoa where within the characteristics of movements there are two that we should always investigate called A, B and A+B motility less than 32%.

It refers to a sperm count of less than 15 million/ml, this is a frequent cause of male infertility, and the origin of this low sperm count will always be fundamental, since according to this, the appropriate treatment will be applied for each case.

We speak of abnormal forms in a sperm count when less than 4% of normal forms (according to Kruger’s criteria) are observed in the total sample.

It is defined as the total absence of spermatozoa in the ejaculate, which can be secretory (originating in the testicle) or obstructive (occlusion at the level of the vas deferens). In both cases, complementary studies such as determination of testosterone, FSH and, if the case warrants it, karyotype, cystic fibrosis, etc., should always be performed.

Medical or structural causes

Vasectomy is a contraceptive procedure that blocks the vas deferens, preventing the outflow of sperm. It can be reversed by recanalization, especially in cases where the couple wishes to conceive.

It is the presence of an increased testicular venous plexus, generating venous reflux, causing an increase in testicular temperature, affecting sperm count and sperm characteristics.
Conditions such as multiple sclerosis, advanced diabetes or neurological injuries can interfere with ejaculation or sperm quality.

The use of tobacco, marijuana, cocaine or steroids can reduce sperm count, motility and morphology. It also increases the risk of genetic alterations in sperm.
