Understanding ovulation and fertilization
While it’s obvious to many, there are plenty of folks who don’t really understand the basic mechanisms about how we get pregnant. If you have been trying for a while without success, it can be frustrating. Maybe this will help.
A woman’s ovaries release an egg every month, about 14 days before the first day of her period. This is called ovulation. When a couple has sexual intercourse (and does not use birth control) around the time of ovulation, a man’s sperm swim to meet the woman’s egg. When a sperm penetrates the egg, it’s called fertilization or conception. The fertilized egg (embryo) then travels to the woman’s uterus (womb), where it burrows into the lining of the uterus and begins to grow.
The best time to get pregnant is a few days before ovulation or the day of ovulation. This is because a man’s sperm can live up to 72 hours after intercourse and a woman’s egg is fertile for 12 to 24 hours after its release. Knowing when you’re ovulating can boost your chances of getting pregnant. If your periods are regular, use an ovulation calculator to get an idea of when you’re most fertile. If your periods are irregular, use one of the following methods. Talk to your health care provider to learn more about the most effective way to use these.
• Purchase a basal body thermometer. Use it to take your temperature before you get out of bed every day. Your temperature goes up by 1 degree when you ovulate.
• Check the mucus in your vagina. It may become thinner, more slippery, clearer and more plentiful just before ovulation.
• Purchase an ovulation prediction kit. Use it to test your urine for a substance called luteinizing hormone (LH). LH increases each month during ovulation.
Having sex as close as possible to ovulation can improve your chance of getting pregnant. Select and watch our video on ovulation and pregnancy to learn more.
