Which tests are commonly used to assess ovarian reserve?

• A. AMH level.
• B. Antral follicle count.
• C. All of the above.
• D. Day-3 FSH and estradiol.

Answer: (C)

Assessing ovarian reserve involves estimating how many eggs remain and how well the ovaries may respond to stimulation. Anti-Müllerian hormone (AMH) level reflects the size of the small follicle pool and is relatively stable across the cycle, making it a convenient single-marker test. Antral follicle count (AFC) on transvaginal ultrasound directly counts the recruitable follicles early in the cycle, giving a snapshot of remaining ovarian reserve. Day-3 FSH, often with day-3 estradiol, assesses pituitary signaling; higher levels can indicate reduced reserve because the body needs more FSH to stimulate fewer available follicles. Because each test provides different but complementary information, all of them are commonly used to assess ovarian reserve.
