Male begins producing semen at puberty. This continues till the end of life.
Yes, How else would it impregnate a bitch?
uh.... if the male is not neutered it needs nothing but the female dog.
A dog's not is a swollen penis. This usually happens when a male dog is tied to a female. When the male dog is ready to release his sperm to his mate, his penis will start to swell into a pink bulb shape on his shaft. This bulb shape is meant to make sure his sperm doesnt come out, and allow the sperm to more likely make his mate pregnant.
Because of its sperm goes in with the urine
no, because his sperm sack has been removed but he can try but no because no sperm is going in to meet the eggs
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.
Dogs are best set for reproduction at 2 years of age.
Yes. Only the testicles on the male have been removed, not the penis. Penetration will still happen, as the male dog can still maintain an erection. There is just no sperm production. Indeed, neutered male dogs can maintain an erection, penetrate a female and actually achieve orgasm, and will "tie" with the female. Most neutered males are less interested in sex due to lowered testosterone levels, but still capable of all the actions. They simply do not produce sperm and cannot impregnate a female.
Yes; for about two weeks after neutering a male can still impregnate a female.
No, 2 different species cannot produce offspring.
It's depending on the number of eggs released by the female. It is the same in humans, thought the twins instances do occur. The male releases millions of sperm that then try to find the eggs once released.
