Roommate skills and precautions

If you want to have a boy, you should choose to have sex the day before ovulation, because it takes a long time for sperm to reach the uterus to the ampulla of fallopian tube and wait for fertilization with eggs in the female genitals. If sperm can arrive ahead of time, it will increase the chances of having a boy.

Both husband and wife should abstain from sex for one week before sleeping together. Before sleeping together, pay attention: The woman washes her vagina with baking soda water, creating an alkaline environment is beneficial to the survival of Y sperm and increasing the chances of having a boy.

Note: the man must wait for the woman to reach orgasm before ejaculation, because women will secrete alkaline substances after orgasm, which is beneficial to the survival of Y sperm and increases the chances of having a boy.

After the end of the same room, the woman should not get up in a hurry. She should put a pillow under her hips for half an hour and get up for cleaning, which can also increase the chance of having a boy.

Eugenics: In order to cultivate a better next generation, couples should quit smoking and drinking about half a year before pregnancy, keep a regular life schedule, and start taking folic acid three months before pregnancy, which can effectively prevent fetal neural tube defects. Finally, I wish the couple who want to have a boy: good pregnancy comes true!
