Timing. According to those who follow the Shettles method, you can up your chances for a girl by aiming to have sex two to four days before ovulation. The theory is that “girl sperm” are stronger and swim slower than “boy sperm,” so they are more likely to survive the wait for the egg to arrive.
How long do boy sperm stay alive?

Does family history determine baby gender?
The researchers also found that the sex ratio for families followed the father’s side, not the mother’s side. For example, if a man had more brothers, his own children were more likely to be male; if he had more sisters, he was more likely to have daughters. This was not found to be the case for women.

Which ovary produces a girl?

Why can’t I have a baby boy?
Sometimes, a mom is less likely to have a boy because one of her X chromosomes is messed up. If the problem is recessive, meaning that having one normal X chromosome is enough to keep the problem at bay, then either of her X chromosomes is fine for a girl child.
What determines if you have a boy or a girl?
Men determine the sex of a baby depending on whether their sperm is carrying an X or Y chromosome. An X chromosome combines with the mother’s X chromosome to make a baby girl (XX) and a Y chromosome will combine with the mother’s to make a boy (XY).
When should I try for a boy?
Timing. According to those who follow the Shettles method, you can up your chances of a boy by making sure you have sex as close to the day of ovulation as possible — ideally within 12 hours of ovulation.
