Antral Follicle Count and Serum Follicle-Stimulating Hormone Levels to Assess Functional Ovarian Age

Catherine McDiarmid-Watt | Sunday, July 29, 2007 | 0 comments

OBJECTIVE: The objective of this study was 2-fold. The first was to estimate side-to-side variation in antral follicle counts. The second was to determine whether basal follicle-stimulating hormone levels on days 2, 3, and 4 of the same menstrual cycle are significantly different.

METHODS: Forty-one patients between the ages of 20 and 42 years undergoing monitoring for in vitro fertilization-embryo transfer were evaluated ultrasonographically for antral follicle number. The antral follicle counts were determined for each ovary by experienced ultrasonographers at the time of suppression check ultrasonography. In a separate study, 62 normal subjects (ages 20–25 and 40–45 years) underwent serial sequential serum follicle-stimulating hormone determinations on days 2–4 of the menstrual cycle, and these levels were compared.

RESULTS: There was no significant difference between right and left antral follicle counts (P = .30). Serial follicle-stimulating hormone values were not significantly different on days 2, 3, or 4 of the menstrual cycle (P = .22).

CONCLUSION: There is no significant difference between right-sided and left-sided antral follicle counts within the same individual. In turn, there is no significant difference in serial follicle-stimulating hormone levels on days 2, 3, or 4 of the menstrual cycle.

About Catherine: I am mom to three grown sons, two grandchildren and two rescue dogs. After years of raising my boys as a single mom, I remarried a wonderful man who had never had a child of his own. Unexpectedly, I found myself pregnant at 49!
Sadly we lost that precious baby at 8 weeks, and decided to try again. Five more losses, turned down for donor egg, foster care and adoption due to my age and losses - we have accepted that there will be no more babies in our house.
