The follicular phase and ovulation phase are very important periods in a woman's reproductive cycle, and the interval between them can help doctors conduct reproductive health examinations and predict women's menstrual cycles. In this article, we will introduce the basic concepts of the follicular phase and the ovulatory phase, as well as the interval between them, to better understand these two periods and their impact on reproductive health.

Next, let’s learn about ovulation. Ovulation usually occurs between days 14 and 20 of the menstrual cycle, but it can occur several days earlier or later. During this stage, the eggs mature and are expelled from the ovaries. The woman's body temperature will rise and she may have symptoms such as nausea, vomiting, headache, etc. Additionally, women may experience an increase in appetite and may feel more energetic.

So, what's the gap between the two? The answer is 7 days. It takes 7 days for an egg to mature and be released from the ovary, so within 7 days of ovulation, a woman's body temperature returns to normal and the cycle begins again.

The follicular phase and ovulation phase are very important to women's reproductive health. If a woman fails to release an egg normally during the follicular or ovulatory phase, it may cause the egg to become fertilized, leading to pregnancy. In addition, if the eggs are not fertilized in time after they mature, they may die in the ovaries, leading to ovarian damage and permanent reproductive impairment. Therefore, understanding the basic concepts of the follicular phase and ovulation phase, as well as the interval between them, is important for women's reproductive health.
