Why does a woman have two ovaries?

There are two ovaries, one on either side of the uterus. Ovaries make eggs and hormones like estrogen and progesterone. These hormones help girls develop, and make it possible for a woman to have a baby. When an egg is released, it's called ovulation.

Simply so, what causes a woman to release two eggs?

Dizygotic twins occur when two sperm fertilize two distinct eggs. In this instance, rather than releasing one egg during ovulation, the mother has released two. (For higher multiple births, more eggs are released - for example, in trizygotic triplets, three eggs are fertilized by three sperm.)

Subsequently, question is, which ovary produces a girl? In the normal female the ovary of the right side yields ova which on fertilization develop as males, and the ovary of the left side yields ova which are potentially female.

Also, what are the two main purposes of the ovaries?

The ovaries have two main reproductive functions in the body. They produce oocytes (eggs) for fertilisation and they produce the reproductive hormones, oestrogen and progesterone.

But having two separate eggs released at different times within the same cycle doesn't happen.
