Final answer:
Typically, only one egg matures and is released from an ovary per menstrual cycle. Occasionally, two eggs may be released, potentially leading to fraternal twins if both are fertilized.
Step-by-step explanation:
How Many Ovum Ripen in One Cycle?
During the reproductive years, typically only one egg matures and is released from an ovary in each menstrual cycle. The maturation and release of the egg is part of the ovarian cycle, a process intertwined with a female's menstrual cycle.
While millions of eggs are present at birth, they begin to mature only after puberty. Once matured, the egg is known as a secondary oocyte and is ready for ovulation.
Occasionally, both ovaries may release an egg, potentially leading to the birth of fraternal twins if both eggs are fertilized.
The ovarian cycle includes the phases of follicle maturation, ovulation, and the formation of the corpus luteum.
After the luteinizing hormone surge triggers the resumption of meiosis, one egg develops into a secondary oocyte and the smaller cell, known as the first polar body, will eventually disintegrate.
