women's oocytes are born. When the fetus leaves the mother and comes to the human body, there are 2 million oocytes in the small ovary of the newborn girl, but these oocytes are still immature primordial follicles.

primary follicles continue to grow and develop in women's lives. More than 99% of the primordial follicles will shrink and decline shortly after they begin to develop. Less than 1% of the primordial follicles can go through puberty, enter reproductive stage, and finally mature into oocytes. Generally speaking,

have only one oocyte mature in each menstrual cycle. According to this calculation, from menarche to menopause, more than 500 mature oocytes can be developed in the lifetime of women around 45 years old. What are the changes of

women during ovulation?

Treble: in addition to the changes in appearance and taste mentioned above, research shows that women's voices become sharper as they approach ovulation. Before and during ovulation, the female voice is the highest. At present, some experts are trying to find out whether high-profile is more attractive to men.

are more attractive to men: some men are divided into two groups: men who smell ovulation women's T-shirts and men who smell ovulation women's T-shirts. The results showed that the testosterone level of the former was higher than that of the latter. High testosterone levels make romantic courtship more likely.

are the most creative: This is the best time for creative activities, because your brain is most active at this time. According to the research of American scientists, as the level of estrogen in the body increases, people's cognitive ability also increases. If your cycle is 28 days, then from day 12 to day 14, your brain will get the best use and your short-term memory will be the strongest. Arrange important meetings and negotiations during this period. You react faster and work more efficiently than usual.

are the most jealous: ovulating women are the most jealous of other women. British researchers showed participants 35 pictures of women's faces. The photos are in uniform black work clothes without any decoration. Participants were then asked to rate the attractiveness of women's photographs at seven points. 0 for least attractive, 7 for most attractive. The results showed that within 12-21 days of physiological period (ovulation period, the most likely pregnancy), women's attractiveness score to other women was significantly lower. However, this "jealousy tendency" will gradually subside with the end of ovulation, and then the evaluation of other women will become positive. During the ovulation period of each month, women tend to envy other women and even belittle their appearance. Its purpose is to "attack others, improve yourself" and win the attention of the most ideal man. How does

calculate ovulation period?

basic body temperature measurement: the body temperature of healthy people will change slightly at different times. The body temperature of adult women fluctuates with the menstrual cycle, especially on ovulation day. Therefore, the ovulation period can be estimated by measuring the basal body temperature. Specifically, wake up in the morning for several consecutive days, measure your sublingual temperature with a thermometer, and then record it. Generally speaking, women's body temperature fluctuates slightly before ovulation. On the day of ovulation, the basic body temperature suddenly drops. After ovulation, the body temperature rises again, then falls again, until menstruation comes.

ovulation pain sensation method: some women will feel slight abdominal pain in one day between menstruation, but a period of time will pass, and there is no abnormal physical examination. This is likely to be ovulation pain, mainly due to the ovulation process, can accurately calculate the date of ovulation.

menstrual cycle estimation algorithm: it is the simplest and easiest to calculate the ovulation period through their own menstrual cycle. The formula is: the first day of ovulation = the shortest menstrual cycle days minus 18 days, the last day of ovulation = the longest menstrual cycle days minus 11 days. The calculation method is based on the first day of menstruation. For example, a woman's previous menstrual cycle has a maximum of 30 days and a minimum of 28 days. The first day of ovulation = 28 days minus 18 days = 10 days. The last day of ovulation = 30 days minus 11 days = 19 days. That is to say, her ovulation period is the 10th day of this menstrual tide, and the last day is the 19th day of this menstrual tide.
