ANATOMY

Detailed explanation-1: -The hormone responsible for these changes is progesterone, which is manufactured by the corpus luteum. Under the influence of progesterone, the uterus begins to create a highly vascularized bed for a fertilized egg. If a pregnancy occurs, the corpus luteum produces progesterone until about 10 weeks gestation.

Detailed explanation-2: -Your ovaries secrete estrogen and progesterone. These hormones play an important role in reproductive development and menstruation. Estrogen production is highest in the first half of your menstrual cycle before ovulation.

Detailed explanation-3: -The menstrual cycle is regulated by the complex interaction of hormones: luteinizing hormone, follicle-stimulating hormone, and the female sex hormones estrogen and progesterone. The menstrual cycle has three phases: Follicular (before release of the egg)

Detailed explanation-4: -A gland called the corpus luteum produces progesterone. Your corpus luteum is a temporary gland that develops after you ovulate (release an egg from your ovary). It’s responsible for maintaining progesterone levels after conception and fertilization to support a pregnancy.

Detailed explanation-5: -What does progesterone do in the menstrual cycle? Progesterone serves a number of functions, but predominantly, it’s there to get your body ready for pregnancy. When an egg is released by an ovary, progesterone encourages the thickening of the uterine lining, ready for a fertilised egg to implant into.
