We all know about eggs, but many people are not very clear about what eggs released by women look like. Today, let's take a look at what eggs released by women look like.
Structurally, the mature follicle releases an egg about 20 millimeters in size, which is surrounded by many granulosa cells arranged radially on the outermost layer of the egg cell, hence also known as the radiating corona. Its inward sequence includes the zona pellucida, yolk membrane outer cavity, and yolk membrane.
Eggs are produced by the female reproductive organ ovaries. When a woman is born, there are 100000 to 500000 primary follicles on each side of the ovaries, surrounded by a layer of primordial follicular cells, also known as granulosa cells, and a basement membrane. These primordial follicles grow in batches at every moment of a woman's life, but over 99% of them decay and degenerate into blocked follicles shortly after they begin to develop. During the reproductive period, only a few hundred follicles fully mature and release mature eggs.
During the reproductive period, there is usually a mature follicle that grows to a diameter of 18-25mm around one month. It ovulates in the middle of the menstrual cycle, about fourteen days before the next menstrual period, and the egg is alternately discharged from both ovaries or continuously discharged from one side. After ovulation, the egg can survive for 1-2 days. Once it combines with sperm during the survival period, it creates a new life. If it does not combine with sperm, the egg will denature and disintegrate, losing its ability to fertilize.
Through the above brief introduction, I believe everyone has a deeper understanding of female eggs. Eggs are an essential part of female fertility, and I hope everyone can learn more about them.
