Predicting and Infuencing Gender

Will it Be a Boy or a Girl? Predicting and Influencing Gender

Can Timing of Intercourse Influence Gender Outcome?

At conception, gender is determined by chromosome characteristics - and it will be the male (or rather the male's sperm) that dictates whether the baby will be a boy or a girl.

Prior to conception, the unfertilized egg carries an X chromosome while the sperm can carry either an X or a Y chromosome. The gender of the baby comes down to one simple event:

If the sperm carrying an X chromosome fertilizes the egg, a girl will be conceived. If the sperm carrying a Y chromosome fertilizes the egg, a boy will be conceived.

Timing Intercourse

Studies indicate that the sperm with the X chromosome - or female chromosome - have a longer life span than the male sperm (with the Y chromosome).

Yet the male sperm appear to have a higher motility. Sperm motility is measured in two ways: percentage of sperm exhibiting movement, and the quality - or dynamics - of this movement, which is called the forward progression. Poor motility means the sperm have a difficult time swimming toward the egg. FertilAid for Men is a non-prescription male fertility supplement that has been shown to improve sperm motility.

Hence, "female sperm" exhibit less motility - yet have a longer life span. The "male sperm" exhibit increased motility, but have a shorter life span than the X chromosome sperm.

It is believed that if intercourse takes place closer to ovulation, then the probability is greater that the child will be male, due to the high motility (forward progression) and the decreased life span of the sperm.

The sperm with the X chromosome - or female chromosome - have a longer life span than the male sperm, but exhibit decreased motility. Therefore, intercourse that takes place earlier may provide increased probability of a girl.

If your trying to conceive count the day you start your period to the date of your next period to find you lmp to figure out your luteal phase calculate the day your pose to ovulate to the day your period starts. You find the day you ovulate by counting the day you start your period as day one the 14th day is ovulation day
