Who decides on twins?

If a family has twin babies, it would be a great joyous event. The probability of a pregnant mother being pregnant with twins is not high, so almost all families hope to have a pair of lovely twins. We all know that the key to having a boy or a girl lies in the sex chromosomes in the man's sperm. So, who makes the decision about having twin babies?

We all know that there are two situations for giving birth to twins. Pregnancy is due to the fusion of sperm and egg, usually an egg and a sperm. Because once a sperm enters the egg, the sperm on the surface of the egg immediately changes sex and can no longer enter the egg. Sometimes two sperm enter at the same time, which will result in twins. These are monozygotic twins, so the twins look different. This is due to the female's body. The other situation is that the female discharges two eggs at the same time and is fertilized at the same time, also resulting in twins. These are fraternal twins, so the twins look almost the same. This is also due to the female's body. Therefore, the decision to have twins is made by women!

Twins can be divided into identical twins and fraternal twins. Among them, identical twins are caused by the combination of a sperm and egg in the early stage of development and the separation into two embryos; fraternal twins are caused by the mother's uterus and ovaries releasing two eggs at the same time, and each of them is fertilized to form a fetus. However, it is all affected by the woman, or it can be directly said to be due to the woman. In other words, if the mother is a twin, the probability of giving birth to twins again is as high as 1.7%, which is much higher than the father.

We all know that eating alkaline foods makes it easier to conceive a boy, and the same is true for having twins. First of all, you need to create an environment that is conducive to having twins. The alkaline human body environment is more conducive to the survival of sperm, which can promote the fusion of more sperm and eggs, thus increasing the chance of having twins. Therefore, if the mother wants to have twins, she should eat more alkaline foods, such as vegetables, milk, oranges, bananas, kelp and so on.
