the epididymis
What causes spermatogenesis to begin
Both the respiratory and reproductive systems begin with "r."
Desires begin to fade and the equipment begins failing to work. Lol
Sperm begin development in the seminiferous tubules of the testes, where spermatogenesis occurs. They then mature in the epididymis, a coiled tube located on the back of each testicle.
spermatogenesis
A female produces eggs from her ovaries. A male produces semen. When these two things come into contact with each other(in the woman's uterus) , the egg is thus fertilized and will begin to develop into a fetus..which then becomes a baby!!:)
Follicle-stimulating hormone (FSH) stimulates the beginning of meiosis during puberty. In females, FSH promotes the growth and maturation of ovarian follicles, initiating oocyte development. In males, FSH acts on Sertoli cells in the testes, supporting spermatogenesis. This hormonal signaling is crucial for the onset of reproductive capability during puberty.
The testes and ovaries begin making active, mature reprductive cells during puberty.
gastrulation A2 Puberty.
Physically, girls are able to reproduce as soon as they get their period, and a boy can impregnate a girl as soon as he can ejaculate. However, the younger a girl is, the higher the risk of death and birth defects.
It is called the cloaca The male chicken does not have a penis and there is no penetration of the female reproductive tract at the time of mating. Instead the female inverts her cloaca which comes in contact with the male's inverted cloaca and receives the sperm. The cloaca is then drawn back into the hen's body and the sperm are captured. They then begin the journey up the length of the reproductive system. The sperm live inside the female reproductive system for up to 10 days and each time an ovulation occurs (every 24-26 hours in good egg producers) the egg can become fertile.
No. The reproductive organs are not mature and hormones are needed to begin the process.
