Follicular atresia means degeneration of follicles. Thus, if all follicles get degenerated at the age of 45-50 years, there will be no ovulation and hence no menstruation which leads to menopause.

Which of the following statements concerning menopause is correct?a)Me...
The correct statement concerning menopause is option C: The onset of menopause is primarily due to follicle atresia.
Explanation:
Menopause is a natural biological process that marks the end of a woman's reproductive years. It is characterized by the cessation of menstrual cycles and the decline in ovarian function. Several factors contribute to the onset of menopause, including the depletion of ovarian follicles.
1. Follicle Atresia:
During a woman's reproductive years, the ovaries contain a finite number of follicles, each housing an immature egg. These follicles are responsible for the monthly release of an egg during ovulation. As a woman ages, the number of follicles decreases. Eventually, the remaining follicles become less responsive to hormonal signals, leading to a decline in ovarian function. This process is known as follicle atresia.
2. Hormonal Changes:
As the follicles undergo atresia, there is a decrease in the production of estrogen and progesterone, the primary female sex hormones. This decline in hormone production can lead to various menopausal symptoms, such as hot flashes, night sweats, vaginal dryness, mood changes, and changes in sexual function.
3. FSH and LH:
FSH (follicle-stimulating hormone) and LH (luteinizing hormone) are two hormones produced by the pituitary gland that play a crucial role in the menstrual cycle. FSH stimulates the growth and maturation of ovarian follicles, while LH triggers ovulation. During menopause, there is a decrease in the production of FSH and LH by the pituitary gland. However, this decrease is not the primary cause of menopause but rather a consequence of the declining ovarian function.
In summary, menopause occurs primarily due to follicle atresia, which leads to a decline in ovarian function and a decrease in hormone production. While there is a decrease in FSH and LH levels during menopause, it is not the underlying cause but rather a result of the follicle depletion. Therefore, option C is the correct statement.
