How big does the egg grow before it is released?

Doctors will carefully observe the maturation time of the follicles in women's bodies during the test tube period to infer the time of egg release. The maturity of the follicles directly determines the quality of the eggs, so if women are preparing to have children, they should try to eat foods that help the growth of follicles and promote better egg quality. People who know something about the mechanism of egg discharge should know that only when the follicle matures to a certain degree can it promote egg discharge, so how big a follicle should be before the egg can be discharged?

How big does the egg grow to be released?

Generally speaking, the follicle will be discharged when it reaches a diameter of about 20mm. Normally, we cannot see the egg before ovulation because it is very small. Only when it develops into a follicle can we see it under a microscope. At that time, it is already very large. The 10th to 14th day before menstruation is called the ovulation period.

A mature egg is generally larger than 20mm, and the smallest one is normal at more than 18mm. The growth from primary follicle to mature follicle can be divided into 8 levels. The first five levels are too small and take too long to grow, so they do not have much practical significance. The focus should be on the 6th level onwards. The diameter of the sixth-level follicle is 5mm; after 5 days, it grows to 10mm and becomes the seventh-level follicle; after another 5 days of development, it reaches the eighth-level follicle with a diameter of 16mm. The 8th level follicles are mature follicles.

Therefore, it takes a total of 10 days for the 6th level follicle to grow to the 8th level follicle, which is exactly the follicular phase in a menstrual cycle. Starting from 16mm, after another 2 to 3 days, it will develop into a 20mm follicle and the egg will be released.

When is the egg released from the body?

The egg is released about 14 days before the next menstrual period. The day the egg is released is the ovulation day. To be on the safe side, we call the 5 days before ovulation, 4 days after ovulation, and the 10 days including the ovulation day the ovulation period. Women with irregular menstrual cycles cannot use this method to infer the time of egg release, but they can check whether ovulation has occurred by measuring basal body temperature, ovulation test strips, observing cervical mucus, B-ultrasound monitoring, etc. During the ovulation period, the body will undergo some subtle changes. Ovulation is often accompanied by symptoms such as slightly higher body temperature, lower abdominal pain, and breast tenderness.
