Hormonal Control in Menstrual Cycle

Which hormone is primarily responsible for stimulating the development of the ovarian follicles during the follicular phase of the menstrual cycle?

• Luteinising hormone (LH)

• Follicle-stimulating hormone (FSH)

• Progesterone

• Human chorionic gonadotropin (hCG)

During the luteal phase of the menstrual cycle, which hormone is secreted in higher amounts to maintain the endometrium?

• Oestrogen

• Progesterone

• Testosterone

• Prolactin

What is the main role of oestrogen during the follicular phase?

• Inhibiting follicle development

• Stimulating the thickening of the endometrial lining

• Triggering ovulation

• Maintaining pregnancy

Which hormone surges to trigger ovulation around the middle of the menstrual cycle?

• Progesterone

• Luteinising hormone (LH)

• Oestrogen

• FSH

What is the primary function of progesterone during pregnancy?

• Stimulating milk production

• Inducing labour

• Inhibiting FSH release

Which hormone is produced by the placenta to maintain the corpus luteum in early pregnancy?

• Oestrogen

• Human chorionic gonadotropin (hCG)

• FSH

• Prolactin

What type of feedback mechanism is involved when high levels of oestrogen stimulate a surge in LH?

• Negative feedback

• Positive feedback

• Neutral feedback

• No feedback

Which hormone inhibits the release of FSH and LH during the luteal phase?

• Oestrogen

• Progesterone

• hCG

• Testosterone

What happens to progesterone levels if pregnancy does not occur?

• They increase

• They remain constant

• They decrease

• They fluctuate randomly

Which hormone is responsible for the development of secondary sexual characteristics in females?
