Description of intervention(s) / exposure
PREPARE Part A is a prospective, observational cohort study enrolling any individual who underwent retroperitoneal lymph node dissection (RPLND) at least six months prior for management of testicular cancer. After consent and confirmation of eligibility, eligible participants will complete a once-off series of health-related quality of life (HRQoL) questionnaires either online or on paper to inform the prevalence of retrograde ejaculation and impact (if any) of retrograde ejaculation on HRQoL. It is anticipated that completion of the questionnaires will take up to 20 minutes.

Participants will also be invited to participate in an optional, semi-structured interview, which will last up to 45 minutes. This will be coordinated at a time convenient to the participant at a later fate.

Statistical methods / analysis
Baseline demographic and clinical characteristics collected during screening in PREPARE will be presented in tabular format and analysed using descriptive statistics and Student t-tests, where comparisons between groups are required. A p value of <0.05 will define statistical significance.
The primary outcome will be summarised descriptively with the prevalence of retrograde ejaculation defined as the number of participants reporting retrograde ejaculation, of all men recruited to this study.
Secondary outcomes will also be summarised descriptively, including mean and median, where relevant. HRQoL measures will be summarised using means and 95% confidence intervals of the means of men experiencing (or not) retrograde ejaculation. An analysis of covariance will be fitted to determine impact of retrograde ejaculation on HRQoL and time from RPLND.
