Purpose: Diminished reproductive function can be a major late effect of childhood cancer treatment. This study evaluates the changes, and occurrence of possible recovery, in gonadal function markers in children treated for cancer. Methods: Gonadal function markers were measured before (T0), directly after (T1), and 1 year after (T2) end of treatment of childhood cancer. Anti-Müllerian hormone (AMH) was measured in girls and inhibin B in boys and compared to reference populations. Repeated measures analysis of variance and t-tests were employed for data analysis. Results: Baseline gonadal function markers (T0) at diagnosis were available in 129 girls and 150 boys. Paired gonadal function markers were available in 49 girls and 54 boys for T0-T1, and in 27 girls and 32 boys for T1-T2. Gonadal function markers were significantly lower than the reference population at each time point (p < 0.001). Post-menarcheal girls showed a decrease in AMH between T0 and T1 (standard deviation scores [SDS] -0.72 to -1.32, p = 0.007), and in the boys cohort, a decrease in inhibin B (SDS -1.14 to -1.43, p = 0.045) was observed. Impaired gonadal function levels (<5th percentile) at T1 were observed in 15 of 27 (56%) girls and in 15 of 32 (47%) boys. However, gonadal function had recovered at T2 in seven girls and six boys. Conclusion: Our data suggest that gonadal function is already compromised at diagnosis and is further decreased by childhood cancer treatment. Nevertheless, about half of the children with gonadal impairment recovered over time. Evaluation of gonadal function markers before 1 year after end of treatment may therefore be unreliable.
