For semen to be transferred to a female vagina, human intercourse must take place. Ejaculated sperm must travel into the uterus via the cervix. Inside her body are the ovaries these contain the ova in immature form from the time of her birth. The vulva has a muscular passage called the vagina that is connected to the uterus at an angle. This in turn leads to the egg tubes and ovaries.
Girls have a urethra that is separate to the vagina and is used for passing out urine from the body.
The urethra opens into the vulva.
