Answer:
follicle-stimulating hormone (FSH) and estrogen.
Step-by-step explanation:
the follicle-stimulating hormone (FSH) is highly synthesized leading to the selection of a dominant follicle that produces the highest levels of estrogen.
In the menstrual cycle, the proliferative phase occurs after the menstrual phase and before the ovulatory phase. During this phase, the endometrium (the lining of the uterus) begins to thicken and prepare for potential implantation of a fertilized egg.
FSH, which is produced by the pituitary gland, plays a crucial role during the proliferative phase. It stimulates the growth and development of multiple ovarian follicles, each containing an immature egg. As the follicles grow, they produce increasing levels of estrogen.
Among the growing follicles, one follicle usually becomes dominant due to its higher sensitivity to FSH and its ability to produce the highest levels of estrogen. The dominant follicle continues to grow and mature, while the other follicles degenerate. The high levels of estrogen produced by the dominant follicle during the proliferative phase have several effects. They promote the thickening of the endometrium, increase blood flow to the uterus, and prepare the reproductive tract for potential fertilization and implantation.
Therefore with this information in mind clearly the correct answer is follicle-stimulating hormone (FSH) and estrogen.
