The key to conceiving a boy is to do “the deed” close to your ovulation. As Dr Shettles points out, male-producing sperm (Y-chromosome) move faster than female sperm. Male sperm also dies pretty fast, while female-producing sperm (X-chromosome) can stick it out and take their time hooking up with the egg.

Can you guarantee a boy?

The only way to guarantee a boy or girl? Currently, the only way to guarantee sex is a technique called preimplantation genetic diagnosis (PGD), where a single sperm is implanted in the egg in a type of in vitro fertilization called ICSI (intracytoplasmic sperm injection).

Who is responsible for baby gender?

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).

By the fourth birth to families with three prior boys, 52.4% were male. The increase varied directly with the number of prior boys (p for trend = 0.0007).

February 29 has the lowest total number of births over the twenty year period because it only occurs once every 4 years. However, the average number of births on February 29 takes into account the day only occurs on a leap year, resulting in a value just under the overall daily average.
