WebThese cells, known as the primary ova, number around 400,000. The primary ova remain dormant until just prior to ovulation, when an egg is released from the ovary. Some egg cells may not mature for 40 years; others degenerate and never mature. The egg cell remains as a primary ovum until the time for its release from the ovary arrives.
