What is the follicular phase?

Female physiology is a relatively complicated process, which is essentially different from male physiology in that female physiology has a certain periodicity, while male physiology does not have this problem. There is a direct relationship between a woman's cycle and the follicles. According to the growth of the follicles, it is divided into three phases: the luteal phase, the ovulation phase and the follicular phase. However, many women do not have a particularly good understanding of the follicular phase and the luteal phase. This article will analyze in detail what the follicular phase and the luteal phase are.

The egg-producing function of the ovaries changes monthly and is generally divided into three stages: the follicular phase, ovulation phase and luteal phase.

1. Follicular phase: This is the stage when the follicles develop and mature. During the development process, the primordial follicle goes through different development stages of primary follicles and secondary follicles, and finally becomes a mature follicle.

2. Ovulation: Under the action of the peak of LH secretion, the mature follicle moves to the surface of the ovary, the follicle wall ruptures, the ovulation hole appears, and the egg cell, zona pellucida, corona radiata and egg fluid are discharged. This process is called ovulation. The released egg is captured by the fallopian tube umbrella and sent into the fallopian tube.

3. Luteal phase: After ovulation, the luteal phase begins. The remaining follicular wall collapses, and blood enters the follicular cavity and coagulates to form a blood body. As blood is absorbed, granulosa cells and endometrial cells proliferate and luteinize, forming a corpus luteum that has a yellow appearance. If the egg is successfully fertilized, the embryo secretes hCG, causing the corpus luteum to continue developing into the corpus luteum of pregnancy.

The luteal phase refers to the period from ovulation to the day before menstruation. The ovaries are affected by luteinizing hormone and secrete progesterone to maintain the thickened endometrium to facilitate the implantation of the fertilized egg. If the fertilized egg does not implant, the endometrium will collapse and the menstrual cycle ends with the onset of menstruation.

After knowing what the follicular phase and the luteal phase are, I believe that all female friends must have a deeper understanding of their own physiological knowledge. Here I would also like to remind all female friends that if you are in the stage of preparing for pregnancy, you must have a more comprehensive understanding of your menstrual cycle, so that you can prepare for pregnancy better and conceive your own baby earlier.
