Dr. Max Gomez: Biological clock countdown

By Dr. Max Gomez

The quality of a woman’s eggs helps determine how likely fertilization is.  As a woman ages, the quality of her eggs generally deteriorates.  A new test helps women understand their own egg quality, and how to choose a course of fertility treatment.

New York, April 30 -- For many couples, the routine goes like this -- you fall in love, get married and have a family.  But with many people now getting married later in life, before you know it the biological clock is ticking louder and louder.

A woman's biological clock has to do with a lot more than just her age.  It's a combination of ability to ovulate and the quantity and quality of her eggs.  Egg quality helps determine whether an egg can be fertilized and whether a pregnancy will continue or fail.  A woman's egg quality generally deteriorates as she ages -- the classic biological clock running out of time.

Normally, the quality of a woman's eggs is evaluated indirectly through a variety of hormone tests.  Now, a test that measures egg quality more directly is getting some attention.  The test looks at an ovarian hormone called inhibin-b.  Ranges of inhibin-b can vary widely, from 45 to 200.  If a woman's inhibin-b level is lower than 45, it can signal a problem with the quality of her eggs.

This test can help a couple and their doctor decide which type of infertility treatment is best.  For more information on inhibin-b testing, the doctor in our story is Dr. Scott Roseff from the West Essex Center for Advanced Reproductive Endocrinology in West Orange, New Jersey.
