Eggs are particularly important for women. Their ovaries store many eggs, and with each menstrual cycle, the number of eggs decreases one by one. The older the person, the fewer eggs they have. Every mother hopes that their child is excellent, so how many eggs are of high quality? Let's learn about it together with the editor below.
What size of egg is considered high-quality
Structurally, the mature follicle releases an egg about 20 millimeters in size, surrounded by many granulosa cells that are 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.
What is an egg
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.
The question of what size of egg is considered high-quality is something that women should have a certain understanding of through the introduction of the editor. In fact, eggs can live for one to two days, especially if they are released within one day. Therefore, women who want to conceive must calculate the time carefully and make the best quality egg become their own child.
