Objective
To evaluate the correlation between chronological and biological age by comparing the normograms of AFC, AMH, and FSH.
Design
Retrospective study
Setting
Data were taken from patients who visited the Infertility Clinic at Dr. Cipto Mangunkusumo General Hospital Jakarta, Indonesia, between January 2008 and December 2010.
Patient(s)
Infertile women who visited the Infertility Clinic.
Intervention(s)
None.
Main Outcome Measure(s)
Normogram of AFC (n = 366), AMH (n = 1616) and FSH (n = 415).
Result(s)
The correlations among AFC, AMH, FSH, and age are statistically significant. Normograms of AFC and AMH with 3rd, 10th, 25th, 50th, 75th, 90th, and 97th percentiles showed a decrease in age where FSH increased. A cut-off value of AFC, AMH, and FSH for poor responders was plotted at the 50th percentile of each normogram. Serum AMH and AFC started to decline in women between 34 and 35 years old. We found a relatively lower slope increase of FSH in older patients compared to that of AFC and AMH. FSH was observed to be a later predictor of biological age than AMH and AFC.
Conclusion(s)
AMH predicted biological age earlier than FSH or AFC. Normograms can provide a reference guide for physicians to counsel infertile women. However, future validation with longitudinal data is still needed.
