Couples master this skill to decide whether to have a boy or a girl

The gender ratio in the world is already unbalanced, but many people still choose to have boys. There is no way that the concept can be changed in a short time, but many people cannot get what they want. Some people calculate the days every day for this, and some people pray to God. In fact, it is not that troublesome to have a boy or a girl. If you master the following points, although you cannot definitely have a boy, the probability will be greatly increased.

Women are more likely to conceive during orgasm

It is easier to conceive during sexual climax. A normal sexually mature male can discharge up to 200 million sperms in one ejaculation, but some of these sperms lose their vitality or die in the acidic environment of the female vagina. If both the man and the woman have an orgasm, the man's semen will have sufficient hormones and his sperm will be more active, which will help them reach the meeting point with the egg earlier and reduce the damage from external factors during the process. For women, orgasm can promote the increase of cervical secretions. The cervical secretions are weakly alkaline, which is beneficial to the movement of sperm and provides nutrition for sperm, greatly improving the survival rate of sperm.

In addition, the study also found that during orgasm, the cervix opens slightly and this state can last for 30 minutes, opening the door wide for sperm. At this time, the position of the uterus is almost in a straight line with the vagina, preventing sperm from taking a "detour", which are all important factors for easy pregnancy.

Orgasm helps to have a boy? Is there a scientific basis for this?

Does orgasm really help to conceive a boy? Director Zhu said that this is scientifically based. We know that the sex of a child is determined by the sperm cell at the time of fertilization. If the sperm with an X chromosome combines with the egg, a girl will be born, and if the sperm with a Y chromosome combines with the egg, a boy will be born. The two types of sperm have different characteristics: Y sperm is light in weight and therefore runs faster, but it has weak resistance and poor vitality and is prone to premature death; X sperm is relatively heavy in weight and therefore runs slower, but it has stronger resistance and a longer lifespan.

Both types of sperm are afraid of acid and prefer a weak alkaline environment. In the acidic environment of the vagina, both types of sperm can survive for about 8 hours. If both types of sperm can pass through the cervix, and the uterus and fallopian tubes have an environment for sperm survival, then the faster Y sperm will be more likely to reach the distal 1/3 of the fallopian tube - the location of the mature egg - and get fertilized, resulting in a greater chance of a male embryo.

When a woman reaches orgasm during sexual intercourse, the secretion of weak alkaline fluid in the cervical canal increases, which not only dilutes the acidic environment in the vagina, but also allows both types of sperm to pass through the cervix alive. The faster Y sperm has a greater chance of combining with the egg first and fertilizing it. Therefore, female orgasm helps to give birth to a boy.

Increased finger movements

When a woman repeats certain movements with her hands, such as moving her fingers or grinding her nails, it means she is nervous and full of anticipation.
