What Is Low Ovarian Reserve?

Low ovarian reserve means the ovaries have fewer remaining eggs than expected for a woman’s age. It does not mean pregnancy is impossible, but it may reduce the chances of natural conception and shorten the reproductive window.

Women are born with a fixed number of eggs, and this number naturally declines over time. In some individuals, this decline occurs earlier or more rapidly than usual.

Ovarian reserve is commonly assessed using:

• Anti-Müllerian Hormone (AMH) levels

• Antral Follicle Count (AFC) on ultrasound

• Day 2–3 Follicle-Stimulating Hormone (FSH) levels

Lower AMH or AFC values may suggest diminished ovarian reserve. These tests estimate egg quantity, not egg quality, which is mainly influenced by age.

Some women have no symptoms. Others may experience difficulty conceiving or a reduced response to fertility treatments.

Early evaluation can help guide informed reproductive planning and timely medical support when needed.
