Study Endpoints
Primary Endpoints
Mean Assay Negativity Rate (ANR) for Ebola Virus During the Treatment Phase
Treatment Phase (assessed at days 4, 8, 11, 16, 20, 24, & 28)

Mean assay negativity rate (ANR) of semen samples collected during the treatment phase on days 4, 8, 11, 16, 20, 24, \& 28. Average of all time points for negative values were compiled for the collected assay values. Negativity rate per participant was calculated using all time points by calculating the number of negative results over total number of time points (7). The assay negativity rate was averaged over all participants to get the mean assay negativity rate.

Mean Assay Negativity Rate (ANR) for Ebola Virus During the Follow-up Phase
Follow-up phase (assessed on weeks 8, 12, 16, 20, & 24)

Mean assay negativity rate (ANR) of semen samples collected during the follow-up phase on weeks 8, 12, 16, 20, \& 24. Average of all time points for negative values were compiled for the collected assay values. Negativity rate per participant was calculated using all time points by calculating the number of negative results over total number of time points (5). The assay negativity rate was averaged over all participants to get the mean assay negativity rate.
