A) Progesterone is primarily produced by the corpus luteum in the ovary after ovulation.
B) The main function of progesterone is to prepare and maintain the uterine lining (endometrium) for the potential implantation of a fertilized egg. It does so by thickening the endometrial lining and increasing its blood supply, in anticipation of a developing embryo.
C) Progesterone exerts negative feedback on the hypothalamus and anterior pituitary, which suppresses the secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). This helps prevent further ovulation during pregnancy and maintains the corpus luteum for the first few weeks until the placenta takes over hormone production.
D) Therefore, all of the statements apply to progesterone.
