For couples hoping to influence the gender of their baby, there is a method to help you do so and it has been around since the 60s. Though the so-called Shettles Method has had its share of doubters, many believes it to be an effective gender swaying method.

In an episode of DZMM's Private Nights, Dr. Lulu Marquez elaborated more on what remains to be the most common way of sex selection.

It was Dr. Landrum B. Shettles, author of the report "How to Choose the Sex of Your Baby", who first discussed the possibility, focusing on the different characteristics of sperm.

"It is the sperm that fertilizes the egg that will determine the sex of your baby," Dr. Marquez said in the radio interview, emphasizing that sperm cells can carry either an X or Y-chromosome.

"If an X-chromosome-carrying sperm fertilizes the egg, the baby will be a girl. If a Y-chromosome-carrying sperm fertilizes the egg, the baby will be a boy," continued Dr. Marquez.

She also further described boy sperm as being faster, smaller, and having a shorter life span than the girl sperm. Meanwhile, though the girl sperm may be slower, it has a longer life span because of its ability to survive in an acidic cervical environment.
