Infertile men can become fathers through a new technique that gives one in five people the opportunity to have children.
The new technology, introduced in five specialized NHA hospitals, involves surgically removing a small portion of the testicle, less than a millimeter, from dissecting it and then recovering the "persistent" spermatozoa inside.
MicroTESE is a specialized microscope that enlarges the tubes 20 times inside the testicles, which is essential for the success of the new technology. He helps the surgeon to find the sperm.
"Many of these men are told that they can not have children, but this technique shows that 10 to 30% of them can have children," says Dr. Chana Jayasina, endocrinologist consultant at Imperial College London.
Surgical procedures that can increase the chances of sperm extraction are offered up to 25%, including sperm retrieval from the inside of the body using a thin needle or removal of multiple 5mm portions testicle for subsequent extraction of semen.
The risk of serious complications, such as narrowing of the testicles and blood clots, can be eliminated, but any tissue taken for biopsy must be expelled, which will delay vaccination for one week and reduce the chances of success of the pregnancy.
With the help of MicroTESE, the surgeons know they managed to extract the semen within two hours, which means that couples do not have to worry about it. waiting for results.
Two weeks before surgery, patients receive a dose of FSH sex hormone to promote sperm production. During the operation, a urologist applies a small incision in the scrotum, allowing access to the testicles.
The surgeon then examines them under a magnifying microscope and identifies the tubes in which the spermatozoa are produced. Inflated tubes may contain sperm, which is cut with fine tools.
The wound is sewn while the urologist takes a biopsy from the extracted tissue and extracts any "stuck" semen from the tubes.
The sperm found is frozen for later use in IVF treatments, with patients able to return home within 3-4 hours.
