Cessation of the menstrual cycle in a woman is called
a. Lactation
b. Ovulation
c. Menopause
d. Parturition

Answer 1

Hint: During a woman's menstrual cycle, as women approach their forty or fifty years age, their ovaries gradually lose their sensitivity to FSH and LH. Menstrual periods become less frequent and. They don't produce viable eggs that can be released. These all events occur at Cessation of the menstrual cycle.

Complete answer:
Let’s, first of all, we study all the options one by one.
> Option A: Lactation-
It describes the secretion of milk from the mammary glands and how long it takes a mother to feed her child. This process occurs naturally in all-female mammals after pregnancy, even though they predate mammals. In humans, the process of breastfeeding is also known as breastfeeding or breastfeeding. New-borns often produce milk from their breast tissue, which is colloquially known as witch's milk.

> Option B: Ovulation-
It is defined as the release of an egg from a woman's ovaries. After the egg is released, it travels down the fallopian tube, where it can be fertilized by sperm.

> Option C: A Menopause-
In human women, the reproductive phase is thirty to thirty-two years. This begins with puberty and ends with menopause. Women's reproductive years are marked by the beginning and end of the menstrual cycle. The first menstrual cycle usually occurs around the age of twelve and is called menarche. The end of a woman's menstrual cycle at the end of the female genitals is called menopause.

> Option D: Parturition-
It is also known as labour (childbirth). It is a mechanism for signalling the start of labour the process of having a baby after the end of pregnancy. The developing child is born with the release of cortisol. During childbirth, the cervix expands and relaxes. Together with cortisol, oxytocin and estrogenic hormones are released to initiate milk production and labour. During labour, the uterus contracts to push the foetus towards the cervix and continues until the foetus descends through the birth canal. In this process, the head must come out first.

Hence, the correct answer is option (C).

Note: The side effects of menopause include excessive sweating (especially at night), hot flashes, headaches, pain in muscles, vaginal dryness, depression, hair loss, weight gain, and mood swings. Oestrogen is involved in calcium metabolism and without it, blood calcium levels decrease. To replenish the blood, calcium is lost from the bones, which can decrease bone density and lead to osteoporosis. Adding oestrogen in the form of hormone replacement therapy (HRT) can prevent bone loss, but it can have negative side effects.
