Definition: The word "csd9" means "Chorionic Gonadotropin," a hormone released during pregnancy that helps regulate fetal growth and development, supports implantation, and regulates sex determination in both males and females. It's also known as FSH, LH, or OXT. Detailed definition: - Chorionic Gonadotropin (CSF9): This hormone is secreted by the placenta (ovary) during pregnancy to support fetal growth, development, and the fertilization of an embryo. The quantity produced is measured in follicular fluid. - FSH: It is a naturally occurring hormone that plays a critical role in pregnancy maintenance and helps regulate the ovarian cycle, including ovulation and the release of eggs. - LH (Luteinizing Hormone): Similar to FSH, this hormone regulates ovulation in females. Its production also contributes to egg maturation and the development of the corpus luteum. - OXT: It's a biological marker that measures the activity of human chorionic gonadotropins. This measure helps in diagnosing pregnancy and determining gestational age. Understanding these hormones is crucial for understanding fetal growth, development, and sex determination, which are fundamental to successful conception and prenatal care.
