Sertoli syndrome

-

There are many couples who, after a year of having unprotected sex, can not conceive a child. It is at this time when you should go to the fertility specialist.

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

Index

Approximately in 30% of the cases it is due to a problem of male infertility and in 25% the problem is of mixed origin, therefore in more than half of the cases of couples with sterility problems the man is involved. At first, the couple is interviewed and a fertility study of both is requested. In the case of man, a semengram is performed, his seminal sample is observed to make a diagnosis and indicate the most appropriate treatment.

Once male infertility has been diagnosed, the specialist should approach it as any other type of alteration or anomaly, first proceed with an extensive questionnaire to find out as much as possible, a medical examination and finally the analytics and studies should be done. laboratory.

Testicles function

The main testicular function is the production of sperm, this process occurs inside the seminiferous tubules and is called spermatogenesis.

There are several cell types inside the testes and each one has a different function in spermatogenesis:

  • Sperm: is the male gamete, that is, has half the genetic content and its union with the ovule will form the embryo. It is the final result of spermatogenesis.
  • Sertoli cells: they are a kind of support cells or nurses, they cover the seminiferous tubules that are responsible for spermatogenesis.
  • Leyding cells: are responsible for the synthesis of androgens. In man there are several hormones such as luteinizing hormone (LH), testosterone and FSH that are responsible for controlling the production of sperm, ie spermatogenesis.

The types of male infertility are classified depending on where the problem is located:

  • Pretesticular causes: alteration at the hormonal level in the hypothalamic-pituitary-gonadal axis.
  • Testicular causes: alterations in the testicles themselves.
  • Post-testicular causes: alterations in the semen already produced or in the seminiferous tubule.

Sertoli syndrome only

The Sertoli Syndrome is also known as Sertoli Syndrome only, in this alteration no sperm is found in the seminiferous tubules, there are only Sertoli cells, therefore man is sterile. This disease is also called germinal aplasia.

The males that present this alteration can not have their own offspring, since without sperm you can not use any technique of assisted reproduction, you must resort to the donation of sperm. Sertoli syndrome produces permanent and irreversible sterility.

There are no other symptoms associated with this syndrome, Leydig cells work normally, LH and testosterone have normal levels, in some cases FSH may be elevated.
