How many dominant follicles are there

Before the egg is formed, it exists in the form of a follicle in the female ovary, and when the follicle ruptures, the egg is formed. There will always be time for follicles to form in a woman's body within a month. If you want to have high-quality eggs, there must be dominant follicles to form high-quality eggs. Because high-quality eggs can increase the success rate of IVF and make IVF healthier, and how many high-quality follicles are there in a woman's body?

The criteria for dominant follicles

Medically speaking, a dominant follicle is a follicle that is larger than 10 mm and smaller than 18 mm in size on ultrasound.

In the first half of the menstrual cycle - the follicular phase, under the action of estrogen. Usually several follicles develop successively and grow gradually. Through B-ultrasound monitoring, we find that near ovulation, there is always one follicle with the largest head, and after it ruptures and ovulates, the other follicles are absorbed and disappear one after another. We call this follicle with the largest head and the most mature development the dominant follicle. If the normal menstruation is 30 days, the follicle that grows to more than 1.0 on the tenth day of menstruation can be considered the dominant follicle.

The dominant follicle is of great significance in infertility treatment. It is the beacon guiding medicine in infertility treatment.

Normal follicle standards

The normal standard for follicle size is that the follicle is round or oval, with a diameter of 18-25mm. If the follicle size is lower or larger than the normal value, it will affect normal ovulation.

You should know that the growth from primary follicles to mature follicles 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 2-3 days, it will develop into a 20mm follicle and the egg will be released.

If the follicles are underdeveloped, forcibly using ovulation-inducing drugs in a short period of time to force ovulation will cause the eggs to be released, but they will be immature and therefore cannot lead to normal conception. Even if the sperm and egg combine, miscarriage, stillbirth, etc. are likely to occur.

What is the non-dominant follicle?

Some women are found to have no dominant follicles during examination, which must be taken seriously. No dominant follicle means that the follicles do not develop well and there are no mature follicles. There are many factors that cause this situation, such as central nervous system anovulation, hypothalamic anovulation, pituitary anovulation, polycystic ovary syndrome, and luteinized unruptured follicle syndrome. Other causes include endocrine system disorders other than gonads, such as thyroid and adrenal cortex dysfunction, and systemic diseases such as severe malnutrition, which can affect the regulation of ovarian function and lead to ovulation disorders.

It is recommended to further examine the endocrine system to identify the cause, which will help with treatment. From the perspective of traditional Chinese medicine, it is mainly due to kidney deficiency, cold uterus, and lack of warmth and gasification of the uterus and uterine vessels. If the moisture is insufficient, it will lead to ovarian dysfunction and poor follicular development. It is recommended that female friends eat some warm, mild and warm-yang foods appropriately. It is also extremely important to maintain a happy mood. A good mentality plays a direct role in the regulation of a woman's own reproductive endocrine system and is extremely important.

The treatment of this condition is mainly directed at the ovaries and other reproductive systems, restoring the normal function of the ovaries, promoting the development and maturation of follicles, restoring normal regular ovulation, and restoring normal menstruation. This fundamentally reflects the normal reproductive function of women, and conception and childbirth will be a natural thing.
