Answer :
Answer:
During in vitro fertilization (IVF) treatment, hormones are administered to women to stimulate the ovaries to produce multiple eggs, which can then be collected for fertilization in a laboratory setting. These hormones interact with the body's natural hormonal system in several ways to prepare it for pregnancy:
Explanation:
Follicle-Stimulating Hormone (FSH): FSH is typically administered to stimulate the ovaries to produce multiple mature eggs. This hormone mimics the natural process that occurs during the menstrual cycle, where FSH levels rise to stimulate the growth and maturation of ovarian follicles containing the eggs.
Luteinizing Hormone (LH): In some IVF protocols, LH may also be administered to trigger the release of mature eggs from the follicles (ovulation). This helps ensure that the eggs are collected at the optimal time for fertilization.
Gonadotropin-Releasing Hormone (GnRH): GnRH agonists or antagonists are often used to regulate the timing of ovulation during IVF treatment. They prevent premature ovulation, allowing for better control over the timing of egg retrieval.
Progesterone: Progesterone is crucial for preparing the uterine lining (endometrium) for implantation of the fertilized embryo. After egg retrieval and embryo transfer, supplemental progesterone is often given to support the endometrium and improve the chances of successful implantation.
Estrogen: Estrogen levels are also monitored and may be supplemented during IVF treatment to ensure optimal uterine lining development. Estrogen helps thicken the endometrium and create a receptive environment for embryo implantation.
