In a normal adult male, both testicles produce sperm cells pretty much continuously. It's not made "on demand", as it were, but is stored until needed (or until the sperm cells die, at which point they're reabsorbed).
Both testicles equally share the work in making sperm.
Sperm cells are made in organs called testes
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.
No, both testicles are responsible for producing sperm that contains genetic material to determine biological sex. The sex of an individual is determined by the chromosomes present in the sperm that fertilizes the egg.
no i am sorry because one of your testicles needs to be active in order to produce the right kind of sperm
The term bilateral means on both sides. So in this phrasing it just means that both testicles have descended from the abdomen into the scrotum. This is what is supposed to happen. It is considered problematic if both testicles have not descended into the scrotum by the time a boy is 1 year old.
During spawning the coral releases both eggs and sperm into the water at the same time. Fertilization occurs in the water.
Yes. I had both testicles removed after an injury. My testicles wasn't functioning and I was in alot of pain. I opted to have the testicles removed after it was offered to me by my doctors. I do take testosterone injections weekly and I function ok. It is difficult in the beginning, but after a year, I'm back to normal.
It depends on whether or not you're able to produce sperm, which, unless there's some extremely weird defect with your internal reproductive system anatomy, I'm assuming you can. There isn't necessarily a correlation between the testicles being in the scrotum and fertility, it's about whether or not you can produce and utilize sperm. If you can, you can father a child.
Both alternate interior and alternate exterior angle pairs lie on opposite sides of the transversal.
Fraternal twins are developed from the fertilization of two separate eggs. In most cases a woman releases one oocyte every month from alternate ovaries. Sometimes an oocyte is released from both ovaries at the same time both of which are fertilized by separate sperm. This results in the development of non-identical (fraternal) twins each having its own placenta for nourishment.
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.
