In human female, menopause is a stage in which
1 oogenesis starts at puberty.
2 menstruation starts at puberty.
3 corpus luteum starts secreting progesterone for maintaining pregnancy.
4 menstruation stops at the age of 50 years and reproductive capacity is arrested.
Explanation:
(d) In human beings, menstrual cycles ceases around 50 years of age; that is termed as menopause.

Menstruation is triggered by a sudden decline in the amount of hormone secreted by corpus luteum. Identify the hormone.
1 Luteinizing hormone
2 Follicle stimulating hormone
3 Progesterone
4 Estrogen
Explanation:
(c) The corpus luteum secretes large amounts of progesterone which is essential for maintenance of the endometrium and the pregnancy but its decrease in secretion triggers the menstrual cycle.

Level of which hormones are at their highest during the luteal phase (second half of the cycle) of the menstrual cycle?
1 Follicular stimulating hormone
2 Estrogen
3 Progesterone
4 Luteinizing hormone
Explanation:
(b) The ovulation (ovulatory phase) is followed by the luteal phase (latter phase of the menstrual cycle) during which the remaining parts of the Graafian follicle transform as the corpus luteum, which produces progesterone. So progesterone is highest at luteal phase.

Which phase of menstrual cycle is also called proliferative phase?
1 Luteal
2 Ovulatory
3 Follicular
4 Menstruation
Explanation:
(c) The menstrual phase is followed by the follicular phase. During this phase, the primary follicles in the ovary grow to become a fully mature Graafian follicle and simultaneously the endometrium of uterus regenerates through proliferation.

Which phase of menstrual cycle is also called secretory phase?
1 Luteal
2 Ovulatory
3 Follicular
4 Menstruation
Explanation:
(a) Luteal phase is also called as the secretory phase of menstruation cycle. The luteal phase begins with the formation of the corpus luteum and ends in either pregnancy or luteolysis. The main hormone associated with this stage is progesterone, which is significantly higher during the luteal phase than other phases of the cycle.
