In menopause, which of the following is seen: March 2013
**Core Concept**
Menopause is a physiological state characterized by the cessation of menstruation in women, typically occurring between 45-55 years of age. This condition is marked by a decline in estrogen levels, leading to various physiological changes.
**Why the Correct Answer is Right**
The decline in estrogen levels during menopause leads to a decrease in the production of inhibin, a protein that inhibits the production of follicle-stimulating hormone (FSH). As a result, FSH levels increase, causing an increase in the production of luteinizing hormone (LH). This increase in LH levels stimulates the growth and maturation of follicles in the ovaries, leading to an increase in estrogen levels.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not accurately describe the hormonal changes that occur during menopause.
**Option B:** This option is incorrect because it does not accurately describe the physiological changes that occur during menopause.
**Option C:** This option is incorrect because it does not accurately describe the hormonal changes that occur during menopause.
**Clinical Pearl / High-Yield Fact**
A key feature of menopause is the increase in LH levels, which can lead to hot flashes and other symptoms. Estrogen therapy can help alleviate these symptoms by reducing LH levels.
**Correct Answer: A. Increase in FSH and LH levels.**
