Progesterone

Progesterone is a hormone produced mostly by the ovaries during the menstrual cycle and by the placenta during pregnancy. It plays a crucial role in preparing the uterus for pregnancy by thickening the uterine lining to support a fertilized egg. If pregnancy occurs, progesterone helps maintain it; if not, levels drop, leading to menstrual bleeding. It also influences other body functions, such as breast development and immune response. Clinically, progesterone can be used in hormone therapy, fertility treatments, and to address certain menstrual issues, reflecting its importance in reproductive health.
