Morphology of spermatozoa

One of the methods for establishing the morphology of spermatozoa is the Kruger study. It involves an evaluation of the external structure of the male sex cells, in particular the head, body and flagella. In this case, violations such as:

• irregular shape of the head;
• change in flagellum length;
• thickening and, at the same time, kink of the flagellum;
• violation of the structure of the acrosomal part of the head;
• doubling tail or sperm head.

What influences the morphology of sperm?

There can be many causes of spermatogenesis . Among the main ones, one should mention injuries, operative interventions on the organs of the reproductive system, exposure to ionizing radiation, high temperatures, and diseases of the genitourinary system.

How is the Kruger research conducted?

The resulting sample of the ejaculate is subjected to coloring with special reagents, after which it is microscopized. At one time, the lab worker calculates and evaluates the morphology of about 200 spermatozoa. The results obtained are compared with those taken for the standard. The result is given in percentages.

Normally, the morphology of spermatozoa should look like this:

• the head is oval in shape, the acrosome is clearly discernible;
• the volume of the acrosome is 40-70% of the entire head;
• the total number of sperm in the correct form in ejaculate - at least 14%.

A distinctive feature of the Kruger study is the fact that spermatozoa are taken into account in the calculation, with both normal and abnormal morphology. This allows you to get a general picture and evaluate the quality of sperm.

How can the morphology of spermatozoa be improved?

Before proceeding to the therapeutic process, the patient is assigned such studies: ultrasound of the prostate, bacteriological analysis of the ejaculate and spermogram, a blood test for sex hormones.

In those cases when the possible cause of morphological disorders is the diseases of the reproductive system, the treatment is directed, first of all, to the elimination of the disease.

Parallel to this, general restorative therapy is carried out, which presupposes the appointment of vitamin complexes, the observance of a certain diet (more fruits and vegetables, less fatty foods). Such micronutrients as zinc and selenium are an essential component of therapy.

It should be noted that no treatment can be effective without giving up harmful habits and changing one's lifestyle. Therefore, it is this advice doctors give primarily to men who apply for help.
