• Progesterone and Esterone levels stimulates pituarty to release FSH to start the proliferative phase

Question 3

Proliferative

Answer 3

• Progesterone promotes Thickening of the Endometrium
• If No implantation occurs and estrogen and progesterone levels are high FSH and LH production is stopped
• Corpeus Lutemum dengernates and decreases progesterone snd estro production
• Low levels of horomones then trigger shedding of endometrium and menstrual phase
