Hate to disagree my son in law had testicle cancer had to have one removed. My youngest grand daughter was born after one was removed. So you do not need both to produce. But to routinely remove from for the pump I dont see it unless they are extremely large and sac extremely small. In that case there would be issues with or with out the implant
There is a difference between fertility with testosterone production.
Testicles have two functions. One to produce sperm and one to produce the hormone testosterone.
You can still produce sperm with one testicle. So, yes, you have a granddaughter because your son-in-law still had at least one testicle. A vasectomy prevents the "delivery system" for the sperm by cutting the vas deferens.
My concern was not about the vasectomy. The removal of one healthy testicle.
In your son-in-law's case, the testicle was removed to save his life from cancer.
The poster I was responding to, was asking to remove a healthy testicle for the sole purpose of making room for the pump of an implant. That in my opinion, is a terrible idea because his production of testosterone would be reduced. That could have impact on libido and other complications of low testosterone. The remaining testicle may work harder to produce the necessary amount. That may cause problems with that testicle.
