Question

What hormonal change occurs after fertilization that causes the endometrial lining to remain intact so that the fertilized egg can successfully implant in it? A. The pituitary gland secretes oxytocin and maintains the endometrial lining. B. The pituitary gland secretes follicle stimulating hormone, which acts on the follicles and stimulates them to produce progesterone. C. The hypothalamus secretes gonadotropin releasing hormone, which maintains the endometrial lining. D. The membrane surrounding the embryo secretes human chorionic gonadotropin, which prevents the corpus luteum from disintegrating. E. The developing embryo prevents the production of progesterone after the breakdown of the corpus luteum to maintain the endometrial lining.

Answer 1

Answer:

Progesterone. A female hormone usually secreted by the corpus luteum after ovulation during the second half of the menstrual cycle (luteal phase). It prepares the lining of the uterus (endometrium) for implantation of a fertilized egg and also allows for complete shedding of the endometrium at the time of menstruation
