Question

difference between mensuration and menarche​

Answer 1

Explanation:

Menarche is the onset of menstruation. The average age for menarche in the United States is now 12.8 years. Menarche is preceded by puberty-induced body changes that occur between ages 9 and 16 years. The age at which menarche occurs is affected by genetic and environmental factors.

Answer 2

Ovulation is when an egg is released from your ovaries to be fertilized. Menstruation, or what is commonly referred to as your period, is the bleeding that occurs after ovulation, if you don't get pregnant. During menstruation, blood, mucus and tissue flow out of the cervix and vagina each month.

Menarche is the starting stage, while menopause is the ending stage of the menstrual cycle in females. Menarche starts at the age of approximate 11-16 years, whereas menopause may occur between the age of 45 – 50 years.
