Together with it is another hormone known as progesterone which prepares the uterus so that the fertilized egg can grow in it. Press PROGESTERONE these keys is also responsible for while on preventing muscle contraction Present of the uterus that can cause the mode! egg to detach from the uterus. FEMALE REPRODUCTIVE HORMONE In addition, FSH (Follicle Stimulating Hormone) and LH (luteinizing hormone) plays a role in the regulation of estrogen-progesterone levels. FEMALE REPRODUCTIVE HORMONE It affects the development of the follicles and maturation of the egg as well as the process of ovulation (menstrual cycle). Press these keys FEMALE while on SECONDARY Present CHARACTERISTICS mode!  Growth of underarm and Press pubic hair these keys Breast development, wider while on hips, smaller waist Present Menstruation Increased secretion of mode! sweat and oil
