Cryptorchidism or undescended testicles are one of the most common defects in the genitals that can cause infertility but also testicular cancer, so it is important to diagnose it early.
According to Dr. Lilia Berenice Leyva Macías, an obstetrician linked to Ingenes, cryptorchidism or testicles that did not descend, occur in about 3% of all births, as in 1% of children over 3 months.
This disorder, which literally means "hidden testicle," refers to a testicle that did not reach its place in the scrotum, which is why it is generally known as a lack of descent of the testicles.
Risks due to undescended testes or cryptorchidism
Untreated cryptorchidism can have deleterious effects over time. There are more cases in premature babies and there are almost no specific symptoms, but the absence of the testicles in the scrotal sac during the review is evident, explains the Ingenes specialist.
In general, the testicle descends spontaneously during the first year of life, but when this does not happen, a surgical correction should be made to avoid infertility problems in the future as well as the development of testicular cancer.
In this regard, it is known that a patient with cryptorchidism in a single testicle has a 75% risk of infertility. If the problem is bilateral, and if the testicles are not lowered, the risk is 50%.
In that sense, patients with undescended testicles are 7 to 10 times more likely to develop testicular cancer than the rest of the population.
Causes of cryptorchidism and infertility
The causes of non-descending testis are not entirely clear, but genetic, endocrine and environmental factors are known to be involved.
Men who have both testicles that do not descend have up to 89% probability of having ejaculated sperm and infertility, explains Dr. Leyva Macías.
For this reason, men who want to be parents and who have been trying for a long time should do complete tests to diagnose serious changes in sperm production, such as Azoospermia, which is the absence of spermatozoa in ejaculate, in addition to cryptorchidism and risk of development. cancer
An alternative to perform this type of fertility tests is with the specialists in Reproduction Biology of Ingenes, who have an Andrology unit and offer several options depending on whether or not there is sperm count.
One of them is the testicular biopsy, through which the sperm are extracted directly from the epididymis so that they fertilize the best egg in the laboratory in order to achieve the dream of having a baby at home with In Vitro Fertilization.
