Obstetricians and gynecologists in the hospital said that it is very rare for pregnant women to give birth to quadruplets through natural conception, with a probability of only one in 700,000, while the probability that all quadruplets are boys is only one in 3.52 million.

It is reported that on June 29th, a pregnant woman in Dancheng, Zhoukou gave birth to a rare quadruplet baby boy. The father of the baby cried and laughed excitedly: At first, he wanted to name the baby "Guotai Min 'an", but now that we have realized it, we hope our country by going up one flight of stairs, so we named the four babies "Prosperity".

The father of the child cried and laughed with excitement: this is our greatest wealth! And named the children: Zifan, Yourong, Wenchang and Yongsheng. I also wish the great motherland prosperity.

Formation of multiple births:

1, identical twins

Because a fertilized egg is separated into two or more independent embryonic cells or cell groups during division, they develop into different individuals respectively. The twins produced by this division have the same genetic characteristics, so they have the same sex, similar personality and appearance.

2. fraternal twins

There are two follicles that excrete mature eggs at the same time or one after another, and these eggs are fertilized at the same time or one after another. Because the embryos come from different eggs and sperm, they have different genetic characteristics, and the babies born may have different looks and genders (that is, twins). Most twins (about 75%) belong to this category.
