The saying 'fate is determined by heaven' does have a certain truth, and the reason why many men lack fertility is that they have been a man without fertility since birth.
So, what innate factors have caused men to lose their fertility? The testicles, which we mainly talk about today, are the seemingly inconspicuous testicles that affect a man's fertility.
Mispositioned testicles - cryptorchidism
Some men do not lack testicles, and their testicles are not underdeveloped, but they still cannot conceive their wives. These men's testicles are not caused by the testicles themselves, but rather by the fact that the testicles have gone to the wrong place - inside the human body.
We all know that the testicles will only live in seclusion within a man's scrotum for a lifetime, and are destined not to enjoy the delicious and delicious environment of the "human continent". Once they grow in the body by mistake, they will lose their ability to produce sperm.
Perhaps someone would say at this point that with the development of medicine, it should have been possible to bring back the testicles long ago. Indeed, in the face of human technology, moving testicles is a piece of cake. However, the trouble is that the testicles trapped inside the body will lose their ability to produce sperm due to unbearable high body temperature. Even with the development of medicine, testicles cannot be saved from the fire in this situation. Therefore, men with this situation will inevitably be unable to have children.
Testicular malformation - Cleft's syndrome
Another situation is that although a man's testicles do not have the wrong position, their own reasons also erase a man's fertility.
Small in size, unable to produce sufficient testosterone, and unable to produce sperm, this is the nature of a failed testicle, which is heartbreaking.
This type of testicle is known as "Kleft's syndrome", and approximately one in every 400-700 people suffers from this disease. If these men do not use special treatment methods, it can be said with certainty that their fertility cannot exist.
