The precious egg is at the moment when ovulation (the process of ovulation)

Chen Shuqin (original)

We know that one of the important functions of the ovary is to provide eggs, and ovulation is an important part of the menstrual cycle.

Earlier, where did we understand where the eggs came from?How does follicles develop?So, when the follicles are mature, how can I ovulate?What is the process of ovulation?After understanding these, how to increase the natural conception rate and how to increase the success rate of contraception?It will have a good guidance.

From adolescence to before menopause, ovarian changes in shape and function, called the ovarian cycle. The development of follicles is an important process for forming the ovarian cycle, and ovulation is one of the most important steps.

Ovulation is the process of ovulation before and after ovulation. The main changes are as follows:

The process of ovulation cells and some cells around it is called ovulation.Before ovulation, the follicle is before ovulation, and the egg cells and the radiation crown float in the follicular fluid.

Bubble wall particle cell layers and follicular membranes and ovarian tissues in their peripherals have become thin.The follicles are protruding from the surface of the ovary, similar to a blisters, and finally ruptured and ovulation.

When ovulation, there is a transparent belt, radiation crown, and granular cells in a small part of the egg hills at the same time.

Since the function of the ovary is the secretion of female sex hormones, the development of the entire follicles and ovulation are closely related to the periodic changes of sex hormones secreted by the ovaries.

The endocrine regulation of ovulation is the emergence of the blood LH / FSH peak before ovulation, and its mechanism:

Esolia (E2) peaks are caused by the positive feedback of pituitary and hypothalamus; the effects of gonadotropin release hormone (GN-RH) and the synergy of progesterone.Under the peak stimulus, the mature follicles finally ovulated.

The emergence of mature follicular wall rupture is the emergence of the LH / FSH peak in the blood, which prompts the ovarian wall to generate a fibrobine iconic activation, activates slim lyon, connecting tissue collagen enzymes, protein soluble enzymes, etc. to dissolve the follicles wall.

The emergence of the LH / FSH peak also increases prostaglandin (PG) and histamine. These two substances can expand the blood vessels of the follicles wall and enhance permeability, which is easy to break.

Under the action of prostaglandins (PG) and nerve, the smooth muscle fiber contraction of ovarian cortex and follicular outer membrane layer prompts follicular rupture and egg cell release.

Seeing Jin Guang’s glittering oocyst, I have always been proud of myself a woman.When I know that the egg is unique every month, I feel that I also seem to have become a proud golden peacock.

Ovulation occurs around the 14th before the next menstrual tide, the eggs can be discharged by the ovaries on both sides, or the ovaries on one side can be discharged continuously.

After the eggs are discharged, collaborative effects such as picking up the tubal umbrella, fallopian tube wall creep, and fallopian tube mucosal cilia activity enters the fallopian tube, and run towards the uterine side along the lumen of the fallopian tube.

After ovulation, the follicular fluid flowed out, the pressure in the follicle cavity quickly decreased, the follicle wall collapsed, and many wrinkles were formed. The follicular granules and inner cells of the follicle wall were invaded inward.Structure, called luteum.

After the luteinization, the luteal cells and follicular luteal cells are formed. The diameter of the luteal cells increases from the original 12-15PM to 35-50pm, and 7 to 8 days after ovulation (equivalent to the 22nd of the menstrual cycle).The peak, about 1-2cm diameter, has a yellow appearance.

If the eggs are not fertilized, the luteal starts from 9-10 days after ovulation, and its mechanism is unknown so far.

During degeneration, the luteal cells gradually shrink and become smaller. The surrounding connective tissues and fibrous cells invade the luteal, which gradually replaces the connective tissue. The tissue is fibrosis and the appearance is white.

The normal ovulation cycle of the luteal function is limited to within 14 days. After the luteal recession, the menstrual tide is tide, and the ovarian has new follicles in the ovaries, and a new ovarian cycle began.

If pregnancy, luteal transforms into pregnancy luteal under the action of HCG, and it will not be degraded until the placenta has been formed at the end of 3 months of pregnancy.

In the period of sexual maturity, except for pregnancy and breastfeeding, the ovaries often repeat the above cycle changes, but in the life of women, only about 400 primitive follicles develop to ovulation. Most of the remaining follicles are in the development process.Degenerate becomes a locking follicle.

The historius of the atresia follicle is degenerate and necrosis of the oocyte, which is cleared by phagocytocytes, the granular cell layer is decomposed, the cell fat degeneration, and the follicles collapse finally fibrosis.

If egg cells are combined with sperm, the crystallization of love begins to form.

The change in the number of follicles in the ovaries

The above is the process of ovulation -luteal degeneration -luteum degeneration -the lock of follicles after the eggs are mature.

After learning, there will be a clearer idea for the knowledge of conception, contraception, and menstruation.

The above are some problems about ovulation. I hope that everyone will understand the ovulation process of women after reading, and it can be helpful to pregnancy.
