1. Control the time of conception: Some studies show that women who conceive at different times in the menstrual cycle may affect the determination of fetal sex. It is said that 2-3 days and 4-5 days before conception can increase the chances of having a girl, while pregnancy within 24 hours after ovulation may increase the chances of having a boy.
2. Control the pH in the body: Controlling the pH in the body can also affect the decision of fetal sex. It is said that the acidic environment is more conducive to the survival of women's sperm. Therefore, if you want to have a girl, you can choose some acidic foods, such as lemon, yogurt, apple vinegar, etc. to adjust the pH in the body.
3. Eat foods rich in magnesium and calcium: Studies have shown that foods rich in magnesium and calcium can help control the pH in the body and help to give birth to girls. It is suggested that pregnant mothers add foods rich in magnesium and calcium such as tofu, cheese, oats, spinach and nuts to their daily diet.
4. Avoid high temperature environment: The normal temperature of male testicles should be around 34℃. If the ambient temperature is too high, it will affect the quality and quantity of sperm, which may lead to a higher chance of having a boy. Therefore, pregnant fathers need to avoid working in a high temperature environment for a long time or staying in a hot tub.
5. Don't exercise excessively: Pregnant mothers should not exercise excessively, especially during ovulation and the first few weeks after conception, because excessive exercise will affect the hormone level, thus affecting the sex of the fetus.
Although the above methods have certain scientific basis, they cannot guarantee the probability of giving birth to girls 100%. The most important thing is that both husband and wife should maintain a healthy lifestyle, avoid bad habits such as smoking, drinking and overwork, and improve the chances of pregnancy and the health level of the fetus.
