How big does a woman's ovarian follicle need to be to be fertile?

If a woman wants to become pregnant successfully, many conditions must be met. First, mature eggs must be released through the ovaries, and the mature eggs must successfully combine with qualified sperm to form a fertilized egg. The fertilized egg must be transported to the uterus through the fallopian tube so that it can implant in the uterus. Any problem in this process will lead to pregnancy failure. So how big must a woman's follicles be for conception?

How big does a woman's ovarian follicle need to be to be fertile?

Only when a woman ovulates normally can a couple conceive normally during sexual intercourse. So how big must the follicle be to allow conception? How to get pregnant as soon as possible? How to determine female ovulation in daily life? Let’s learn more about it below.

How big does the follicle need to be to be fertile?

1. When the diameter of the follicle reaches 18-25mm, it will be discharged naturally. The size of the follicle when it is released depends on the individual. Some follicles are released when they grow to 15mm, while others need to grow to 25mm. Follicular development is a continuous process, and the normal follicle diameter should be between 18-25mm.

2. When a woman reaches menarche, the number of follicles in her ovaries reaches 300,000 to 500,000. Every month, a batch of follicles develop, of which only one dominant follicle can fully mature and release an egg, while the rest degenerate on their own. Only 400-500 follicles develop, mature and are released during a woman's lifetime. The growth from primary follicle to mature follicle can be divided into 8 levels. It takes a total of 10 days from the 6th level follicle to the 8th level follicle, which is exactly the follicular phase in a menstrual cycle. Starting from 16mm, after another 2-3 days, it will develop into a 20mm follicle and then be discharged.

3. The size of mature follicles: Generally, follicles larger than 20mm are considered mature and can be discharged. The size of the follicle when ovulation occurs depends on the individual. Some ovulate when the follicle grows to 15mm, while others need it to grow to 25mm. Under normal circumstances, mature follicles will be discharged within one to two days, and the discharged follicles can generally survive for 2 days. There are usually one or more follicles. But usually only one mature egg is released each month, while the others atrophy or are absorbed by the body.

Regarding the question of how big the follicle needs to be to get pregnant, you can go to the hospital and ask the doctor about this. Consult your doctor for relevant knowledge, which will increase your chances of conception.

Tips: The egg is most fertile within 15 to 18 hours after being released from the ovary, and can maintain its fertilization ability for about 30 hours. The egg then begins to degenerate, and its ability to fertilize rapidly weakens and disappears. That is to say, the egg can generally survive for 1-2 days after being released from the follicle and entering the fallopian tube. Therefore, conception is only possible if sexual intercourse occurs within 1 to 2 days before or after a woman's ovulation. This is very important in guiding the sexual life of infertile couples.
