Both ovaries do not release mature eggs at the same time. Only one egg is, suppose, to be released each month by one of the ovaries, not both. If both ovaries release two matuâ¦re eggs and they are then fertilized, fraternal twins will be conceived.
Answer: Women have a pair of ovaries on either side of uterus. The main function of the ovary is reproduction. Ovaries contain unfertilized eggs which are also called ovum. The eggs mature every 28 to 30 days in an adult woman and get released from the ovary into the fallopian tube to get fertilized. There are certain conditions in which even after adulthood the eggs do not mature in the ovaries. Immature eggs in ovaries is the main cause of infertility in women.
