Female reproductive function after treatment of childhood acute lymphoblastic leukemia

Background The aim was to evaluate self‐reported reproductive characteristics and markers of ovarian function in a nationwide cohort of female survivors of childhood acute lymphoblastic leukemia (ALL), because prior investigations have produced conflicting data. Procedure Self‐reported reproductive characteristics were assessed by questionnaire among 357 adult 5‐year survivors, treated between 1964 and 2002, and 836 controls. Ovarian function was assessed by serum levels of anti‐Müllerian hormone (AMH), follicle‐stimulating hormone (FSH), and inhibin B and by antral follicle count (AFC).
