Answer 1

Explanation:

Hlw Mate...

The first occurrence of menstruation at the age of 12 in females is called menarche. Menarche is the beginning of the reproductive life of a girl. Menstruation stops when a woman reaches the age of 50 approx. At this age she loses her ability to bear child in her womb, i.e., she becomes infertile. This stage of permanent stoppage of menstruation is called the menopause. Thus, reproductive life of a woman starts at menarche and ends at menopause.

Answer:

Menarche is the beginning of menstrual cycle or menses in the females whereas Menopause is the ceasing of menstrual cycle in females.

Menarche occurs between 11-13 years of age whereas Menopause occurs at 45-55 years of age. Menarche occurs due to increase of hormones like LH and FSH whereas Menopause is due to decreased concentration of LH and FSH in the blood.
