Diagnosis of oligospermia: seminogram and hormonal analysis

-

The oligospermia or oligozoospermia is a seminal alteration that consists of having a small amount of sperm in the ejaculated semen.

Since oligospermia does not produce any symptoms that the male can recognize, it is difficult to find out about this condition until the couple tries to have a child and can not.

The oligozoospermia can be diagnosed by a fertility specialist with these two simple tests:

Seminogram also called spermiogram . It is used to evaluate the sperm parameters of the semen with a microscope. Blood analysis provides information on the levels of male sex hormones and if there is any alteration.

Below you have an index with all the points that we will discuss in this article.

The seminogram

The semengram is the main diagnostic test in an andrology laboratory to confirm semen quality. In addition to the concentration of sperm, it also provides data on mobility, morphology, vitality, etc.

To perform this test with the maximum guarantees, it is necessary that the man keep 3 to 5 days of abstinence. Next, the sample must be obtained by masturbation in the clinic, where the ejaculate is collected in a boat and taken to the laboratory for analysis.

A sample of semen has oligozoospermia when the concentration is less than 15 million sperm per milliliter.

The seminal sample is left to liquefy in the laboratory and then proceeds to do two types of examination:



Hormone analysis

Once the oligospermia is diagnosed with the semengram, the blood test can help us find out the cause that is causing it.

The hormones that influence male fertility are the following:

FSH is produced by the pituitary gland and its function is to stimulate the production of sperm in the testicle. A high FSH value indicates that spermatogenesis is not effective and a lower number of sperm is produced. The normal values of FSH are 1.0-12.0 mUI / ml. It inhibits Bes secreted by the testis and acts in the regulation of spermatogenesis causing the amount of FSH to decrease. Therefore, high levels of inhibin B confirm that there is sperm production. A normal inhibin B value would be 140 pg / ml.

In conclusion, there is an inverse correlation between the levels of FSH and inhibin B.

According to the latest report of the Spanish Fertility Society (SEF), in 2016 were carried out 138,553 cycles of in vitro fertilization (IVF) and 36,463 cycles of artificial insemination (AI), which resulted in a total of 37,503 babies born . This represents an increase of 8% in the use of assisted reproduction techniques with respect to the previous year, which shows that more and more couples need help to have the opportunity to become parents. After a year of sexual intercourse without achieving pregnancy, a couple is considered to have sterility problems, so it is advisable to start doing diagnostic tests and determine the most appropriate assisted reproduction treatment in each case, as we will discuss throughout this post.
