Female glands are inside the body - Ovary- females have 2 ovaries; which have a life time supply of eggs -during Puberty the ovaries begin to release one egg cell each month, from there the egg travles through the fallopian tubes to the uterus - in the uterus the egg cell can be fertilized by sperm if not then it will contnue down to the vagina and the female will have her period.
