What is the average size of the ovaries?

The ovaries are the female gonads that are responsible for producing more than twenty hormones, including eggs and sex hormones. They are important organs for maintaining reproductive function and various body functions. Only when the ovaries function normally can women's physiological health be guaranteed. The development of the ovaries begins with the sex differentiation of the fetus, and the state of the ovaries is different at different stages. What is the normal size of the ovaries?

There is one ovary on each side, which is gray-red, tough, flat and oval in shape, with a convex surface. The surface is smooth in young girls, but after sexual maturity, the surface often becomes uneven due to the enlargement of the follicles and scarring after ovulation. The size and shape of the ovaries also vary with age.

In the same person, the left and right ovaries are not the same, and the left side is usually larger than the right side. The average length of an adult ovary is 2.93cm on the left and 2.88cm on the right; the average width is 1.48cm on the left and 1.38cm on the right; the average thickness is 0.82cm on the left and 0.83cm on the right; the weight of the ovary is 3-4g.

A woman's ovaries begin to shrink between the ages of 35 and 45, and after menopause, their ovaries shrink to half their original size.

1. What is the normal size of the ovaries?

Experts point out that the normal size of a woman's left and right ovaries is usually not consistent, and the left one is usually larger than the right one. The average length of an adult ovary is 2.93 cm on the left and 2.88 cm on the right; the average width is 1.48 cm on the left and 1.38 cm on the right; the thickness is -0.82 cm on the left and 0.83 cm on the right; the weight of the ovary is 3 to 4 g, which are all manifestations of the correct period.

2. Function of the ovaries

(1) Reproductive function. In women of childbearing age, except during pregnancy and lactation, the ovaries undergo cyclical changes and release eggs every month, with ovulation usually occurring between the 14th and 16th day of the menstrual cycle.

sky. The egg cell is secreted and discharged from the follicles in the ovary. Among the development of several follicles, usually only one matures, so only one egg matures every month.

The egg survives for several hours after ovulation. At this time, if the egg enters the fallopian tube and meets the sperm, it will be fertilized and become a pregnant egg (fertilized egg).

For the baby, the mother's ovaries are like a small garden, and this small garden has been formed when the mother was very young. There are many seeds in it, and they will grow as the mother grows.

In addition, the garden needs to be fertilized regularly. The estrogen and progesterone (or progesterone) secreted by the ovaries are equivalent to this kind of fertilizer. The main function of estrogen is to promote the growth and development of female reproductive organs and the appearance of female secondary sexual characteristics; the main function of progesterone is to promote the continued growth and development of the endometrium on the basis of the action of estrogen, preparing for the implantation of the fertilized egg in the uterus. Therefore, only with moderate fertilization and watering can the seeds grow better.

The seed grew and matured, and finally one day it left the garden that gave birth to it and went to another place - the fallopian tube, waiting for the arrival of sperm.

Oocytes (eggs) are produced by follicles, which is one of the functions of the ovaries. When a baby girl is born, each ovary contains about 750,000 primordial follicles. As she ages, most of the primordial follicles gradually disintegrate and disappear.

Starting from puberty, a certain number of follicles grow and develop each month, but usually only one follicle matures (in about 28 days) and ovulates. The diameter of a mature follicle can reach about 1 cm and protrude from the surface of the ovary.
