Basal follicle stimulating hormone level correlated to age is a good prognostic criterion for the outcome of intracytoplasmic sperm microinjection.

Background: Age and increased FSH serum level in women are prognosis criteriae associated with decreased fertility.

Objective: The aim of this study was to investigate whether age-specific FSH concentration can be a predictor of the outcome of ovarian stimulation in women undergoing IVF.

Methods: A total of 676 women undergoing their first IVF cycle over a 3-year period were included in this retrospective cohort study.
