Nature wants you to reproduce, the vagina is a somewhat hostile place for sperm trying to survive, and they have a distance to travel, if only one sperm at a time was released from ejaculation then the chances of getting pregnant would be virtually nil and the human race would die out.
Also sperm die after a time even in the scrotum so they are continually replaced.
Because the vagina, fallopian tubes and uterus are a somewhat hostile environment and most of the sperms are inactivated or killed before they reach the ovum.
Male cones produce many pollen grains to enhance its reproductive rate & hence its evolutionary success
its function is to produce the egg so that the sperm from a male can fertalize it and make a babe
Spermatogenesis occurs so that the sperm can join with an egg from a female and produce offspring.
Produce sperm and to give you extreme pain when a ball comes flying in!
The scrotum of a male, is outside the body, because sperm production requires a cooler environment then the internal body. So, the external location actually is required for production of the sperm.
Yes. Doves reproduce sexually so the sperm and the ovum (egg) are needed to produce young.
Only one sperm is needed to produce a baby, but when diagnosing male infertility, the rule of thumb is that the man must produce at least 2ml of fluid, with 20 million sperm per ml (so 40 million in a sample), half of which must be motile and correctly formed. If he meets all of this criteria, he is considered fertile. This is tested after 3 days of no sexual activity.
The male is still a male so he does produce sperm. If the male had intercourse before he got his surgery that may be another way that reproduction is possible. But males still genetically make sperm and no matter what a woman turned man does not make sperm b/c inside/naturally they were still a woman unable to make sperm. The only difference is the tool they use has been changed or evolved
Testes produce sperm, which is required for reproduction for males. So yes, if there are no testes then the person cannot reproduce.
Oh, 70 to 80 years or so.
So much, that if you started counting you would forget what you were doing. It is uncountable.
Yes. You need both the egg and the sperm to produce a fertilized egg which will result in an embryo who will be born. The female has the eggs and the males have the sperm, so you need both present.
