Follicle is the "predecessor" of the egg. It is excreted from the ovaries and is composed of oocytes and its small follicle cells. Among them, the growth of follicles: divided into original follicles , growth follicles and mature follicles.
In one month, the follicle sizes of women are also different, so it is very important to understand the number of follicle days and size, so it can be seen that the actual development of the follicle is. This will select high-quality eggs and sperm to help female friends conceive.
How do follicles develop?
Follicle development process in women is divided into 4 stages, namely the original follicle, the growth follicle, and the mature follicle, which lasts about 3 months.
original follicle: follicle in a rest state, there is an primary oocyte in the center . The gap junction between granule cells and oocytes plays a role in supporting and nutritional oocytes.
Growth follicles: is divided into primary follicles and secondary follicles. Among them, follicle stimulating hormone (FSH) receptors gradually appear in primary follicles; in secondary follicles, FSH induces granule cells to produce aromatase , and estrogen is also synthesized at this time.
Mature follicles: volume increases rapidly, with a diameter of about 20mm, and protrudes toward the surface of the ovary. Mature follicles usually discharge eggs around 14 days before menstruation.
However, because the length of menstrual cycles between individuals is different, the ovulation time of
is also slightly different. The growth of follicles depends on
. A certain amount of follicle stimulating hormone (FSH) and
.
is also regulated by many factors,
such as growth differentiation factor-9 (GDF-9), etc.
Follicle days and size control table
In each menstrual cycle, with the change of hormone levels in the body, dozens of follicles enter the growth cohort at the same time and begin to grow.
Eggs that can form hormone receptors on the cell surface can develop normally. Follicles that do not form hormone receptors will be atresia and disappear one after another, so in the end only 1 to 2 can mature and form dominant follicles.
These 1-2 follicles will slowly develop, and as the menstrual cycle develops into dominant follicles, it will be ruled out, and the chance of conceiving with sex is relatively high at this stage.
How to judge the quality of your follicles
Observe whether there is leucorrhea?:
Most of the time, our leucorrhea is sticky and not elastic. When a woman's body enters the ovulation period of , the estrogen in the body will increase accordingly, and leucorrhea will turn into a thin egg white.
hormone tests in 1 menstruation:
hormone tests in 1 menstruation, you can understand your own ovarian function and see whether follicle-stimulating hormone FSH and luteinizing hormone LH are within the normal range. Poor endocrine will affect follicle development and inhibit ovulation;
ultrasound to see follicle ultrasound The shape and size:
①The high-quality follicles are round or oval, with a diameter of 18-25mm;
②The follicles have an echo-free zone, which is clear and pure, and have clear boundaries;
③Usually, mature follicles will be discharged within 1-2 days, and the discharged follicles can survive for two days.
Look at estrogen:
You can draw blood to see estrogen. Generally, 200-300pg/ml represents a mature follicle.
How to raise large and round follicles?
1. Foods rich in zinc
Foods rich in zinc can improve the vitality of eggs, so it is recommended that sisters who are preparing for pregnancy should eat more foods rich in zinc. For example, beans, peanuts, cabbage, beef, eggs, walnuts, etc.
2, soy products and fruits
Eat some fresh fruits such as red dates, fig , cooked rehmannia , yam and other fresh fruits every day. This will make women's complexion rosy, menstruation regular, and also improve the quality of eggs and maintain good fertility.
3, stay away from harmful substances
1 Car exhaust, industrial emissions and other substances will cause chromosomal mutations in the eggs. Flammable substances, pesticides, antioxidant metabolites 4-ethylene, tobacco, etc. will also affect the quality of the eggs, thereby affecting fertility.
4, multi-exercise
1 Appropriate physical exercise can improve women's physical fitness, which can not only relieve bad mood, but also improve endocrine, maintain ovaries, and provide help in ensuring egg quality.
5. Regulate mood
Heavy psychological pressure will affect the patient's endocrine level, lead to hormonal disorders, and thus affect the health of the egg. Therefore, you must remember to relax and relieve stress during pregnancy and IVF.
6. Maintain adequate sleep
Adequate sleep helps repair the body and adjust endocrine levels. Excessive "nightlife" will disrupt the biological clock, lead to endocrine disorders, affect ovarian function, and affect egg maturation and ovulation.
