Preconception Preparation for Conceiving a Girl: Women should prioritize acidic foods, including dairy, eggs, fish, and meats (e.g., beef, chicken, pork, fish) as well as fruits (e.g., tomatoes, oranges, strawberries, grapes, pineapples, apples)!Timing of Intercourse—Normal sexual activity can continue two to three days before ovulation without restricting frequency. While some suggest more frequent intercourse may reduce Y-sperm count, the optimal rhythm is every other day. Those wishing to try may decide based on their own physiological conditions.
Vaginal pH Regulation—Before ovulation, clear, abundant mucus is secreted. This mucus blocks sperm from entering the uterus. Y sperm are less tolerant of acidic environments; if they linger too long in the vagina, they may be eliminated before reaching the cervical opening. X sperm, however, adapt better to acidic conditions and can swim to the uterus, facilitating successful conception.Intercourse Positions—During intercourse, avoid female orgasm whenever possible. Men should adopt shallow penetration positions to allow ejaculated sperm to remain in the acidic environment briefly, naturally eliminating Y sperm and leaving only X sperm. Recommended positions: Side-lying, Extended, Cowgirl, Rear-side.
