The relevant content of estradiol and progesterone during ovulation is as follows:

Estradiol is a female hormone mainly composed of cell membrane and nuclear endoplasmic reticulum. It is one of the very important hormones in the female cycle. It can help maintain the female menstrual cycle, regulate female sexual desire and mood, and can promote embryonic development. Estradiol production varies throughout a woman's menstrual cycle, peaking during ovulation.

Progesterone is a female hormone made primarily from cells in a fertilized egg. It is one of the most important hormones in the female cycle. It can help maintain the female menstrual cycle, promote embryonic development, and can also affect female sexual desire. Progesterone production varies throughout a woman's menstrual cycle, peaking during ovulation.

In a woman’s menstrual cycle, apart from the ovulation period, other times are also called safe periods. During the safe period, a woman does not have any sperm or eggs in her reproductive tract, so she cannot become pregnant. However, safe periods are not always safe, as women may experience some additional risks, such as infection or illness.

In addition to estradiol and progesterone, there are many other important hormones in the female cycle, such as estrogen, progesterone, and testosterone. They all have an important impact on women's reproductive processes and can affect women's reproductive health in different ways.

In short, estradiol and progesterone play a very important role in the female reproductive process. Understanding their role, and how to maintain a healthy reproductive state, is important for women's reproductive health and well-being.
