Ovarian decline. In the later reproductive years.
While most healthy older women who become pregnant have uneventful pregnancies and healthy babies, thousands more are unable to achieve pregnancy because of declining ovarian function. A decline in ovarian function is normal with increasing age. A woman's number of eggs steadily decreases from a peak at mid-gestation of 7 million to approximately 400,000 at puberty. Certain tests can reflect gradations in ovarian reserve status and predict a woman's potential fertility. The most important lab test is the day 3 follicle-stimulating hormone level. A constant source of frustration in fertility centers is that patients are referred to the specialty clinic too late, when diminished ovarian reserve is so marked that treatment success is severely limited. Earlier assessment of ovarian function would alter this unfortunate trend.
