What Is the Connection between the Luteal Phase and Pregnancy?

After the eggs and follicles are discharged, the pressure in the follicular cavity decreases, the follicular wall collapses, and the granulosa cells protrude into the cavity, forming many folds. Cells and connective tissue of the follicular membrane and blood vessels also invade the granular cell layer. At this time, the capillaries in the inner layer of the membrane bleed, and the cavity was filled with serous fluid and blood. These are called blood bodies. Then under the action of luteinizing hormone, the cells divide further. At this time, the cytoplasm will have yellow pigment particles and lipid droplets, which appear yellow to the naked eye, hence the name corpus luteum. What is the female luteal phase? It can also be said that the remaining follicles after ovulation quickly form a new endocrine gland. The development of the corpus luteum and its results depend on whether the eggs released by the follicles are fertilized. If there is no fertilization, they will degenerate after about 12-14 days, at which time women's menstrual cramps will appear. If the egg has been fertilized, the corpus luteum can be maintained until 6 months of pregnancy before it begins to degenerate.

What causes luteal formation and dysplasia, and insufficient progesterone secretion? This may be related to

The diagnosis of corpus luteum insufficiency can make a preliminary judgment based on basal body temperature. If the basal body temperature rise is not high enough, the difference between the body temperature before ovulation and after ovulation is less than 0.5 (the body temperature rises by about 0.5 after normal ovulation); The possibility of incompleteness is high. At the same time, endometrial biopsy can be used to determine the degree and grade of glandular secretion for a clear diagnosis. Conditional hospitals can measure progesterone levels. If the progesterone peak is less than 10 ng / ml, luteal function is considered to be insufficient. What is the female luteal phase-the normal value is generally above 14 ng / ml. The diagnosis of corpus luteum function should be cautious, and it usually requires observation for more than two cycles to confirm the diagnosis.
