===About the Female Reproductive System===
: There are two '''ovaries''' in a [[female]].
: The '''ovaries''' release one [[ovum]] every 28 days.
: Each [[ovary]] takes a turn to release the [[ovum]] each month, but in some [[female]] humans both '''ovaries''' release an [[ovum]] at the same time which can lead to [[Fraternal Twins|twins]].
