Question

Cessation of menstrual cycle in females is known as
A. Parturition
B. Sterility
C. Menopause
D. Lactation

Answer 1

Hint:It is known as the point in time when menstrual cycles end permanently due to the normal degradation of ovarian oocytes due to ageing.

Complete answer:
Menstruation is a monthly shedding of the lining of the uterus of a woman. Menstruation is also known as menses, cycle or period, or menstrual period. The sequence of events from one menstruation to the next is called the menstrual cycle.

The vigorous contracting of the uterus allows the foetus to be expelled out from the mother's body. This process of delivery of the foetus (childbirth) is called parturition. Lactation is the process of milk secretion. The mammary glands of the female undergo differentiation during pregnancy and the milk development process called lactation begins near the end of pregnancy. Sterility is the state of being unable to produce an offspring.

The first menstruation starts at puberty and is termed as menarche. Menstruation happens every month and continues on till menopause. Menstrual cycle in humans ceases at about 50 years of age. This cessation of the menstrual cycle is referred to as menopause. It occurs naturally as the ovaries age and produce less reproductive hormones.

Thus, the correct answer is option C i.e., Menopause

Note:The first day of the period is considered the beginning of the menstrual cycle. The average cycle length is 28 days; however, the duration of the cycle will range from 21 days to around 35 days. Menopause is the natural cessation or cessation of a woman's menstrual period, indicating the end of fertility.
