Ovarian reserve testing is a vital tool in assessing a woman's fertility potential and planning for family building. As women age, their ovarian reserve naturally declines, impacting fertility and reproductive outcomes. This article explores the significance of ovarian reserve testing, the methods used, and its implications for reproductive planning.

As a woman grows older, her fertility declines. A woman has about 1-2 million eggs at birth, and this finite number does not increase later in her life. At puberty, this number drops to half a million. These eggs are gradually ovulated from this finite pool every month, and the remaining number of eggs gradually diminishes. This reduction commences after 30 years of age, and after 35 years, there is an accelerated loss of quantity and quality. A healthy woman in her 20s has a 1 in 4 chance of conceiving every month. But at 40, she has just a 5% chance of getting pregnant per cycle. The reduction in the number of healthy eggs released with age reduces and delays the chances of conception, increases risk of miscarriage and chromosomal abnormalities such as Down’s syndrome.
A woman’s fertility potential largely depends upon the number and quality of her remaining eggs – medically called ‘Ovarian reserve’.
By assessing ovarian reserve, healthcare providers can estimate her remaining reproductive time, assess prognosis and success rates of treatment provide tailored recommendations for a reproductive plan and fertility treatment. The fertility specialist will expedite treatment and conception in a woman with low ovarian reserve.
The 21st century has witnessed an increasing trend toward delayed marriage and childbearing. Couples who voluntarily postpone parenthood should be aware of the natural decline in fertility with female ageing. Couples must be apprised that the aging process cannot be slowed, halted or reversed. Assessment of ovarian reserve and greater awareness will assist them in making the right reproductive life plan.
Ovarian reserve testing has significant implications for reproductive planning and fertility treatment:
Ovarian reserve testing provides valuable insights into a woman's fertility potential, aiding in reproductive planning and treatment decision-making. By assessing ovarian reserve through methods such as AMH levels, FSH levels, AFC, and comprehensive testing panels, individuals can better understand their reproductive health and take proactive steps to achieve their family-building goals.

If you want to check your FSH and Estradiol, day 2-4 of your menstrual cycle will be the best time to take a test. If you want to check your AMH (Anti-Müllerian Hormone), you can take the test anytime. AFC (Antral Follicle Count) is an ultrasound that counts the resting follicles and is best taken in the follicular phase – the beginning of your menstrual cycle.
The ideal range varies according to what you are testing. For AMH, the ideal range is 1.0-4.0 ng/mL; for FSH, it is below 10 IU/L; and for AFC, it is 10-15 or higher. These ranges will decrease with age, meaning the higher the woman’s age, the smaller the required range, as a woman’s ovarian reserve decreases with age.
A woman’s ovarian reserve starts declining once she enters her 30s. Low egg count when you are 35 means the ovarian reserve is declining, and you should act fast if you want to still get pregnant. You can start by making small lifestyle changes, such as improving your diet and exercise regimen, and avoiding alcohol and smoking. Consult a fertility specialist and start taking the prescribed supplements. You can even consider freezing your eggs or using donor eggs in the future, when you plan to have a pregnancy.
Irregular or light periods, short periods, and difficulty in conceiving can indicate a low ovarian reserve. Some women may even experience early menopausal symptoms like hot flashes, night sweats, or vaginal dryness. An ovarian reserve test that checks various hormones and also looks at the resting follicles through an ultrasound can help confirm the actual reserve.
