Solution

Sr. No. Menarche Menopause
1. Menarche is the first occurrence of menstruation in a human female during puberty. Menopause is the permanent cessation or disappearance of menstrual cycles in a woman.
2. It generally occurs at a young age, typically between 11 and 13 years. It usually occurs in older women, typically between the ages of 45 and 55 years.
3. It signifies the beginning of the reproductive phase and the ability to conceive. It signifies the end of the reproductive phase, as ovulation and menstruation stop permanently.
4. This process is triggered by the initial rise in female sex hormones like estrogen. This process is caused by the gradual decline and eventual stop of female sex hormone production.
