Conceive a boy and a girl during the first month of ovulation

Among them, a woman's menstrual cycle and the location of fertilization are also one of the important factors that affect the pregnancy of a boy and a girl. Generally speaking, the fertilization position for women during ovulation is at the beginning of the month, while the probability of fertilization for women at the end of the month is lower. Therefore, many people believe that women who are fertilized at the beginning of the month are more likely to conceive a boy, while women who are fertilized at the end of the month are more likely to conceive a girl.

However, this statement has no scientific basis. In fact, conceiving a boy or a girl is determined by many other factors, such as female chromosomes, male body structure, environmental factors, etc. Therefore, we should not rely too much on the location of fertilization to determine whether a boy is pregnant or a girl is pregnant.

Also, it's important to note that sex is determined by chromosomes, not by the location of fertilization. Therefore, a woman has a chance of having a boy or a girl, regardless of her menstrual cycle and the location of fertilization.
