On Tuesday, December 3, a 36- year-old man ended up being the 3rd known individual to get a testicle transplant.

The guy, who went through the transplant in Belgrade, Serbia, wasn’t born with any testicles and got one testicle from his twin bro, the New York Times reported.

The two previous testicle transplants were performed almost 40 years earlier, and both likewise included identical twins.

Being born without testicles is unusual. According to the National Institutes of Health, only 0.15%of full-term male infants are born without testicles. (It’s more typical– about 3%of full-term male children– to be born with undescended testicles, however in the majority of those cases, the testicles drop to the right position prior to they’re 6 months old.)

When a guy’s testicles are nonexistant, he experiences both reproductive- and hormone-related problems, Dr. Bobby Najari, the director of the Male Fertility Program at NYU Langone Health who was not associated with the transplant, informed Expert.

Although the hormone-related issues can be fixed with hormonal agent replacement therapies, just a testicle transplant can potentially help a guy born without testicles gain reproductive capabilities.

Testicles have both hormone and reproductive functions

The testicles serve 2 purposes. They launch the hormonal agent testosterone, which is responsible for a guy’s muscle development, facial hair development, and sex drive, according to the Urology Care Structure. If a guy does not have testicles, he will not release testosterone and requires to get the hormone through a replacement method, Najari stated.

Replacement techniques include injections administered by the man himself or his doctor, oral medications, or topical medications.

The testicles likewise play a primary role in recreation, given that they contain the sperm required to fertilize an egg, which turns into an embryo and after that a fetus. Without testes, a guy can’t have genetic children of his own.

Even with a testicle transplant, a man who previously had no testes isn’t guaranteed to have kids, Najari said. That’s because it would need an extra surgical step during which a surgeon connects the vas deferens– the male reproductive organ that connects the sperm to the urethra at the tip of the penis– to the recipient’s own penis.

If the vas deferens isn’t connected to the recipient’s penis (it wasn’t this brand-new transplant case), then the sperm have no other way of leaving the scrotum, entering the penis, and exiting the penis in the kind of ejaculate, according to Najari.

If the vas deferens are connected, it adds about an hour to the procedure, which is already about three hours long, Najari stated.

Testicle transplants are rarely performed

Testicle transplants need cosmetic surgeons be exceptionally physically adept since they should fuse the contributed testicle’s capillary with the recipient’s blood vessels in order for the donated testicle to function properly, according to Najari.

However the difficulty of the procedure itself isn’t why testicle transplants are unusual, Najari said. Rather, it’s due to the fact that “you’re transplanting the donor’s sperm into the recipient, so the recipient’s children are going to be the testicular donor’s children, from a genetic viewpoint.”

It’s not typical for individuals to want to donate their sperm to a complete stranger in this capability, or for a deceased organ donor to grant this while alive, which describes why the 3 transplants finished so far have actually been with twins.

Testicle transplants could be advanced for transgender individuals, wounded soldiers, and cancer survivors

Although testicle transplants are uncommon, the procedure has the prospective to change the lives of individuals in need of a testicle, Najari stated.

Transgender males who aren’t born with male reproductive organs, for instance, could have more reproductive alternatives if they got a testicle transplant.

Furthermore, wounded soldiers and cancer survivors who lost their testes could benefit from the procedure if they do not wish to use other testosterone-providing approaches or wish to have children.
