Which test is indicated for assessing ovarian function?

The test used to assess ovarian function is Estradiol. Estradiol is a form of estrogen, which is primarily produced by the ovaries. During the menstrual cycle, the levels of estradiol fluctuate and are closely related to the functioning of the ovaries. Measuring estradiol levels can provide valuable information about ovarian health, including follicular development and ovulation. High or low levels of estradiol can indicate various conditions affecting ovarian function, such as polycystic ovary syndrome (PCOS), menopause, or potential ovarian dysfunction.

Other tests, while important for assessing different endocrine functions, do not directly evaluate ovarian function. For instance, TSH (Thyroid Stimulating Hormone) measures thyroid function, which can influence reproductive health but does not directly assess the ovaries themselves. Similarly, cortisol is involved in the body's stress response and metabolism, and DHEA Sulfate is an androgen produced by the adrenal glands, neither of which specifically reflect ovarian activity or function. Therefore, estradiol is the most relevant test for assessing ovarian function.
