The results vary. If you are being treated for testicular cancer, you will likely also be treated with hormones that will reduce the sex drive to a point where you won't care about sperm count. Once your treatment is over, it is quite possible that your sperm count will rise again, although obviously not to the previous level.
If you are concerned about fathering children, artificial insemination with your own sperm is an option in many cases.
Not by much, but it kills a couple sperm cels.
The overall Count will be a bit lower, but if that testicle is healthy, the man will still be fertile.
Not if only one testicle is removed. You can produce sperm just fine with only one testicle
There is no testicle fluid in the sac. The testicles create sperm and this is released when a man ejaculates. Hope this helps.
Although it is possible to father a child if only one testicle is removed, some surgeons recommend banking sperm as a precaution in case the other testicle should develop a tumor at a later date.
It should not affect performance however may effect sperm count and reproductive capability.
Most likely his sperm count would be half what it would be with both testicles. May be less depending on why he has only one. Since it only take one sperm to fertilize an egg, he can still be a father.
If he has a testicle, there will be sperm.
The Testicle is what produces sperm in the male human body.
If both are healthy, both will produce sperm.
This will depend upon the exact state of the testicles. If both testicles are retained within the body wall, the dog will be infertile and produce no viable sperm. If only one testicle is retained within the body wall and the other has descended into the scrotum, the dog will produce viable sperm but likely have a low sperm count. If only one testicle is retained but it is outside the body wall although not in the scrotum, the dog will produce viable sperm and may have a normal sperm count. However, cryptorchidism (retained testicles) is a highly inherited condition, and it is likely that the dog would pass this defect on to his offspring. For this reason, most veterinarians and responsible breeders will advocate for the dog to be castrated and removed from the breeding pool.
zero, but get a sperm count to be sure
