As a child I had to use hormones because my testicles did not come to scrotem, if that had not happened, then I was probably unfruitful now. I have three children, and I would like to return to this state, if I steal my testicles in my body and keep them there, will they automatically produce less testoron or not? or can you destroy your testicles by always keeping them at that high themed temperature, 36 to 37 degrees in your body ?

thanks Peter

I don't think they will.

It will reduce sperm production.

As testicles tend to produce more when they are a couple of degrees centigrade below body temperature.

Hey, I'm no medical student but I think you'll be fine. I'm more curious what happens if you take them off and put them on your nightstand

Just messing, good luck whatever you do with your boys

If I m understanding you correctly, you had two undescended testicles as a child. You took hormones to get both testicles to later descend into your scrotum. Then you successfully impregnated a woman to have 3 children with your sperm.

Now you are wondering if pushing both testicles back up into your body will stop your sperm production and if that will affect your testosterone production ?

Heat can make a man sterile. But its very difficult to be sure your sperm production gets low enough and stays low enough to be reliably sterile to avoid unwanted impregnations. You can look up the prometheis website on male contraception research to read about heating methods that have been done in the past and more recent ways to make men sterile for more information on heat sterilization.

Testosterone production is claimed to be less heat sensative than sperm production. But many males with undescended testicles can end up with non functional or only partially functioning undescended testis. There is a claimed greater risk of developing testicular cancer in undescended testicles due to the greater heat of being inside the body instead of being in the cooler scrotum.

Your testicles did very well to make enough sperm to father 3 children. It sounds like you wish to be sterilized to not have any more children. Would a simple vasectomy achieve your goal ?

How would you plan to get your testis back up through your inguinal canals and not drop back down into your scrotum ? Most men s testis are anchored to the bottom of their scrotum to prevent the testis from pulling back up into the abdomen and getting lost or twisted up around other organs in your abdomen floating around free on just the spermatic cords.
