Recently, good news came from the entertainment industry - Xie Na gave birth to twins, a pair of cute little princesses! What a joy! There are indeed many celebrities in the entertainment industry who have twins, such as Fan Weiqi, Lin Zhiying, Zhang Yuqi, Yang Wei, Song Xiaobao... and so on.

Many people began to speculate whether celebrities used any "means" to give birth to twins so easily? Some people are also speculating whether they went through in vitro fertilization? Why are twins more likely to occur in in vitro fertilization? Some people say that in vitro fertilization can produce twins at one time. Is this idea correct? Shen Jie, deputy chief physician of the obstetrics department of Fudan University Obstetrics and Gynecology Hospital, pointed out that in vitro fertilization is to cultivate fertilized eggs outside the body and then transplant them into the woman's body to help her conceive. The reason why twins are more likely to occur is because in order to improve the survival rate of embryos in the body, 2 to 3 embryos are transplanted each time, so the chance of twins is indeed higher. "According to regulations, currently in vitro fertilization, patients can only transfer up to two embryos. For mothers with three pregnancies, the average delivery time is around 33 weeks, and for mothers with twins, the average delivery time is around 35 weeks. There is a risk of premature birth. It’s conceivable,” said Deputy Chief Physician Shen Jie.

Some people say that in vitro fertilization can produce twins at one time, two at a time. Deputy Chief Physician Shen Jie pointed out that in fact, the success rate of IVF is 30% each time, and considering that ovulation induction drugs are actually harmful to the mother's body, it is still recommended for women who can conceive babies on their own. Conceive naturally.

But for older female celebrities, in vitro fertilization is also very possible.
