How IVF increases your pregnancy success in one cycle?
Our bodies have natural, built-in systems to protect us from having too many babies. IVF can override some of these mechanisms to help those with infertility conceive. In an IVF cycle, eggs are harvested and fertilized outside the body (or in vitro).
Here’s how IVF reworks female hormones:
To lower your chances of having too many babies at a time, your natural cycle tends to grow many ovarian follicles just to ovulate a single egg each cycle. This is orchestrated by a tight system of hormonal control by a trio of conductors: The hypothalamus (a higher center in your brain), the pituitary gland in your brain, and your ovaries.
Normally, your menstrual cycle is controlled by the hormones FSH and LH, released by the pituitary gland in your brain, and estrogen and progesterone, made and released by your ovaries. Your higher brain center, called the hypothalamus (a small gland), makes a hormone called GnRH (gonadotropin releasing hormone), which controls the amount and timing of FSH and LH release, which in turn, direct your ovaries’ efforts to grow follicles, ovulate, and prepare the uterine lining or embryo implantation and early pregnancy.
How will your fertility doctor rewire this system in IVF treatment? Your fertility treatment will:
