Arm Label

Cohort A: Partcipants who Received Valganciclovir

Cohort B: Untreated Participants

Arm Description

Participants with donor positive (D+)/recipient negative (R-) cytomegalovirus (CMV) serology, who receive valganciclovir prophylaxis according to the local prescribing information, will be observed for spermatogenesis up to 52 weeks post-transplant.

Outcomes

Primary Outcome Measures

Change in Sperm Density From Baseline to the End of Treatment (EOT)
Sperm density was calculated based on the average of two semen samples. Change was calculated as the sperm density measured at post-baseline visit (EOT) minus (-) the sperm density measured at baseline for each participant. A negative change from baseline indicated a lower sperm density (worsening).

Secondary Outcome Measures

Change in Terminal Uridine Nick-End Labeling (TUNEL) Score From Baseline to EOT and End of Follow-up (FU)
Sperm DNA fragmentation change (chromatin damage) was evaluated based on TUNEL score.
