Hormones That Play A Part In Conception



The hormones that a woman’s body produce play an important role in conception. If some of the hormones that a woman’s body produces don’t function properly, conception is unlikely or even impossible. Likewise, from the date of conception forward, there are hormone changes that occur in a woman’s body.

It is important to understand what hormones do what tasks in regard to conception. The first hormone of mention, Follicle Stimulating Hormone, or FSH for short, works with the ovaries to help it produce and release mature eggs. Each egg that is released is a part of what is called a “follicle.” Each follicle then works to produce the hormone estrogen.

The hormone estrogen helps your cervical mucus to be more hospitable to sperm, making it more likely that conception could occur. In addition, increased estrogen prompts the release of another hormone. This hormone, known as luteinizing hormone or LH, prompts the egg to come out of its follicle, where it can be fertilized. The shed follicle becomes a “corpeus luteum.” In fact, the time from when you ovulate to when you start your next period is referred to as the “luteal phase.





The corpeus luteum then starts to produce progesterone, another hormone. Progesterone helps the uterus to maintain its lining so that a fertilized egg can implant. Progesterone raises your Basal Body Temperature. Many women who are trying to conceive also test their Basal Body Temperature as well, so that they can tell when she has ovulated.

Once an egg is fertilized on the date of conception, hormones change. Soon, within around 7 to 10 days, a woman’s body will begin to produce the hormone human chorionic Gonadotrophin (better known as hCG). This is the hormone that is measured in a pregnancy test. Levels of hCG will continue to change and grow, doubling every two to three days. Levels hormone human chorionic Gonadotrophin of will reach their peak around the third month of the pregnancy, after which they will begin to decline again.
