Yin and Yang are different, and men and women are different.

One yin and one yang is the Tao, but yin and yang are different, just like the yin and yang ions in junior middle school chemistry, the physical positive charge and negative charge.

Yesterday's topic was the integration of yin and yang, and the husband and wife should become one. This is from the perspective of treatment, and both factors should be considered when treating; Different yin and yang, different men and women, is to analyze the characteristics of male and female fertility, as the poem of Su Zizhan, which we learned in junior high school, said, "From the side of the ridge, it has become a peak, with different distances."

There is a great difference in fertility between men and women. Women only ovulate once in a menstrual cycle, and the reproductive cycle is very short. The sperm count unit of male ejaculation is 1 100 million, and the growth period is very long, so we can only draw a conclusion after the coffin is closed.

1. When will it shine? Female reproductive period, such as flowering period, is beautiful but short.

Female fertility is closely related to age. The fertility of both men and women reaches its peak at the age of 24, and the so-called beauty is full of children, which decreases with age. This trend is not particularly obvious for men, but it is very obvious for women. "How long will it take to be bright and fresh?" Just like flowering, "How long will it last?" At that time, the crane was in chaos. "In the 20 cycles of embryonic development, the number of germ cells reaches a peak, about 6-7 million, about 2 million at birth, only 300,000-400,000 when the cardamom is young, and only about 400 beautiful women will become mature follicles in their lifetime. The rest will either be bridesmaids to accompany the bride on the road or not develop at all; The fertility of women at the age of 35 is only 50% of that at the age of 25, and it drops to 25% at the age of 38, and may further drop below 5% at the age of 40.

Generally speaking, the older a woman is, the worse the treatment effect is. If you are a dream, what is the geometry of happiness? So the ancients took the time to travel by candlelight at night; The flowering period is very short, the female reproductive period is very short, and the fertility of older women becomes worse, so the treatment effect is not good. Therefore, the older the woman is, the more active the treatment plan is.

Second, the male reproductive period is long, depending on the coffin.

In the past, it was generally believed that male fertility was not affected by age. It is recorded in Historical Records Family of consorts that "Emperor Wu was seventy years old and was born to Zhao Di". Liu Che, Emperor Wu of the Han Dynasty, met Mrs. Gou Jian (a boxer) in his 60s, and gave birth to Liu Fuling, the later Emperor Zhao of the Han Dynasty, at the age of 70. At the age of 88, Su Dongpo's best friend married Mr. Zhang's concubine 18. But with the increase of age, the probability of pregnancy will decrease. Under the same normal sexual life, it takes a longer time (about 6 times) for men over 45 to get pregnant than men over 25. Campbell urology also pointed out that compared with young men aged 25, men over 40 are 50% less likely to get their spouses pregnant within 1 year.
