Are testicular transplants possible?

Where are you going to find a donor? Don’t look at my sack that way.

My guess is probably yes it is possible. But, total guess. I think the sperm would be your own, if it is possible for the testical to supply sperm after transplant. But, total guess.

I think storage time for sperm is around 10 to 14 days. So you might be shooting his guys for a bit, but I’m guessing after that it would be your own DNA.

It has been done already.

But that was his own testicle returned after being frozen for two years or so.

I would think that because the equipment producing the sperm is of a different DNA make-up, the sperm would match the donor of the testicle. Larry Niven in his book A Gift From Earth explores this possibility a bit.

Any guys crossing your legs or squeezing them together while reading this?

Would require a certain amount of courage to proceed with that kind of op, count me out, I don’t have the balls see.

You need to remember that with any transplant (unless the donor is yourself, as in @whitenoise ‘s article), even when there is a best possible donor match, you need to take large amounts of drugs to keep your body from rejecting the organ and killing it. These drugs can severely hamper your immune system and many people with donated organs have to be very careful about not catching a cold or getting sick at all.

I don’t think the compromised immune system or the risk of gangrene or septic shock that could happen if the body rejected the testicle would be worth getting a transplant. As much as men love their balls, nobody needs them to stay alive.

The sperm produced by the testicle will always have the DNA of the testicle, not of the recipient, because the sperm is formed by cells in the epithelium of the seminiferous tubule of the testicle by a process of cell division. The cells being divided don’t get new DNA just because they’re transferred to another body.
