No peer-reviewed publication reporting this trial's results has been linked yet. This can indicate results are unpublished — a known publication-bias signal. We re-check periodically.
Summary
This observational study will compare spermatogenesis in male adult renal transplant recipients receiving valganciclovir versus untreated matched controls. Data will be collected from each participant for up to 52 weeks post transplant.
