Male Infertility

Reproductive System

In an adult man, the formation of sperm (spermatogenesis) in the testes is done continuously. The germination cells (unspecialized cells) require approximately 90 days to develop and form a mature sperm and be taken to the epididymis (body adjacent to the testicle). They are stored in the epididymis until the moment of ejaculation.

After passage through the epididymis, sperm is carried by channels (vas deferens), through the prostate and joining with the fluid produced by the seminal vesicles to form the seminal fluid. At the time of ejaculation, the liquid travels through the urinary tract (urethra) to be eliminated to the outside. The ability to release an adequate amount of sperm into the woman’s vagina is a very important factor for male fertility. Any change in the emission mechanism and / or production process can lead to infertility.

A very common reason for change in seminal production is increased body temperature generated by fever or prolonged exposure to excessive heat, chronically (eg, hot baths, bathtubs, among others) that can reduce sperm production and their ability to move and increase the amount of sperm with altered shape in the semen.

The formation of spermatozoa is most suitable at around 35°C, a temperature slightly below the basal body temperature. This is the reason for the location of the testes in the scrotal (scrotum) and the ability to approach and retraction from the body to maintain a temperature regulatory mechanism.
