If you are pregnant at an advanced age, please check these three hormones: AMH, FSH and E2 estradiol, to fully assess your ovarian “reserve”. AMH is found in the granulosa cells of all primordial and initial follicles. The higher the AMH level, the more abundant the ovary will be in the future, and the lower the level, the more limited the egg supply. Some experts suggest that AMH <2(ng/ml)→ indicates aging ovarian function and suggest early planning for pregnancy and childbirth. 2, FSH follicle stimulating hormone Blood test for FSH (follicle stimulating hormone) on day 3-5 of the menstrual cycle can be used as an indicator of egg stock in the ovaries. FSH<8(IU/L)→ shows normal egg stock. FSH>10(IU/L) → egg stock is declining. E2 Estradiol E2, also known as “Estradiol”, is a female hormone secreted by ovarian granulosa cells. AMH>2(ng/ml)→normal value. The role of E2 in stimulating endometrial proliferation can be used to assess ovarian function, and E2 concentration decreases at menopause. There is an absolute relationship between egg quality and age. In summary, if a woman over 30 years old is considering having a baby, she can first go to the hospital for a gynecological ultrasound to assess the condition of the uterus, ovaries and follicles, and to draw blood to measure AMH, FSH and E2 to assess the current and future ovarian function.
