Ovulation: Chances

Get Pregnant: It is during ovulation that you are at your most fertile. If you are trying to get pregnant, timing intercourse around your ovulation can greatly increase your chances of conception.

To increase your chances of conceiving a girl, you should have intercourse 3-4 days before ovulation. Men produce two types of sperm — those carrying the X or female chromosome, and those that carry the Y or male chromosome. These two types of sperm are different in several ways: the male y-sperm cells are smaller, weaker, but faster than the female x-sperm cells, which are bigger, stronger, but slower. Therefore, if you have sex 3-4 days prior to ovulation, you have a better chance of conceiving a girl, because the weaker male sperm cells will die off, and the female sperm cells will be available in greater quantity when the egg is released. See Getting Pregnant for more information.

You are likely to be most fertile on the day of ovulation and during the four or five days just before ovulation. Studies have shown that to increase your chances of getting pregnant, you should have sex once a day during your fertile days. Sperm can live for a few days and the egg can live about a day, so most experts suggest you try every other day or every day starting about 5 or 6 days before you expect to ovulate, up through the day of ovulation or the next day.
