In 737, li Longji, a 52-year-old tang dynasty son, did a very absurd thing: he summoned His 18-year-old daughter-in-law, Yang Yuhuan, the princess of Shou, into the palace to relieve his boredom. Since then, the two have been entangled and double-lived for nearly 20 years, and the strange thing is that Yang Yuhuan, who is at the age of Fang, did not give birth to a son and a half-daughter? After careful investigation and analysis, I believe that there are mainly the following reasons:
First, Li Longji is too old to lose his fertility
First of all, it should be clear that Li Longji has strong reproductive ability, and before meeting Yang Guifei, he already had 30 sons and 29 daughters.
Looking at Li Longji's age, he was 52 years old at the time. There are two problems, one is that the age is too big, although men in their fifties and sixties still have fertility, but the quality of sperm can not be compared with when they were young, the probability of successful conception is reduced a lot; on the other hand, Li Longji has many children in the early stage, and his fertility has been seriously overdrawn, and he cannot have children.
Lee Long-ki
In theory, a qualified sex life may have children, but in fact, there has never been a shortage of women in the emperor, and the number of children is very limited, indicating that there is still a limit to men's fertility. Li Longji already had nearly 60 children in front of him, which is a very large number, and he has not had children with other concubines since then, indicating that his fertility has been exhausted.
Second, Li Longji did not want Yang Yuhuan to conceive his child
Even if Li Longji, who is in his fifties, is unlikely to let Yang Yuhuan become pregnant even if he has fertility, for two reasons:
First of all, after all, Yang Yuhuan was once his daughter-in-law, if he had another child with himself, this relationship was too chaotic, and the pressure of public opinion was not allowed;
It's not good to spread this kind of picture
Secondly, the Yang family is flying high, and if she has children, it will be detrimental to the rule of the Li family. With the favor of Yang Yuhuan, the social status of the Yang family has risen sharply, and it has begun to become flying and invincible. For example, another time Li Longji's sister went to find Yang Yuhuan's sister, and as a result, they did not even lift their butts, nor did they let Li Longji's sister sit down and chat, Li Longji was very angry after hearing this, and twice threw Yang Yuhuan out of the palace, but he really couldn't do without her, and then he took her back.
There is a very interesting scene in "The Biography of Zhen Huan": the emperor likes Nian Qianyao's sister Huafei very much, and most of the nights he stays with her, but Huafei is not pregnant, and later everyone knows that Yongzheng secretly manipulated her a long time ago.
Whether it is the guilt of his son, the fear of public opinion, or the fear that the Yang family's arrogance is too arrogant, Li Longji has reason to secretly manipulate and make Yang Yuhuan unable to conceive a child. For example, often used beauty products - Yang Taizhen hongyuqing, the main ingredients are peony danpi, almonds, talc, light powder, recently my wife is pregnant, I checked it in advance, almonds, talc is a big taboo for pregnant women. As for whether Yang Yuhuan took the initiative to choose, or Li Longji secretly made it bad, I think it is possible.
Third, Yang Yuhuan suffered from infertility or took the initiative to take contraception
Yang Yuhuan married Shouwang at the age of 15, during which he had no children for 3 years, which is a not very normal phenomenon, and it is very likely that Yang Yuhuan suffers from infertility.
There is also a possibility that Yang Yuhuan took the initiative to take contraception measures. There are three reasons for this:
First of all, Li Longji was already in his 50s at the time, more than the average life expectancy of the emperor, and could hang up at any time. At this time, his other sons were all adults, even if Li Longji loved her very much and gave birth to a son who became the prince, it was not necessarily a good thing, and Li Ji's tragedy was likely to repeat itself on her.
Secondly, Yang Yuhuan could not pass the hurdle in his heart, after all, he had lived with Li Mao for three years, and now he was mixed with his father, if he had another child, he was really sorry for Li Mao, the king of Shou;
Shou Wang's melancholy eyes, can Yang Yuhuan face it calmly?
Finally, stay in shape, in order to continue to compete for favors. Although Yang Yuhuan's favor is not only by beauty, her musical talent also accounts for a large component, but because of her stubborn temper and frequent confrontation with Li Longji, the contradictions between the two are continuous, and there are two experiences of being thrown out of the palace, during this period, Li Longji and other favorite women, presumably Yang Yuhuan's sense of crisis is also quite large.
Summary: In the golden age, Yang Yuhuan spent nearly 20 years with Li Longji, and has never had children, in addition to objective infertility, subjectively Li Longji and Yang Yuhuan have the possibility of choosing contraception.
