This study aims to better understand the effects of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, virus that causes the coronavirus disease 2019 (COVID-19), on male fertility.

After being informed about the study and potential risks, all patients giving written informed consent will produce a sperm sample by masturbation. Patients will also complete a questionnaire relating to their state of health. Six month following the first sperm sample, patients will produce another sperm sample by masturbation. These sperm parameters will be compared with the ones from a sperm analysis performed less than 2 years before the SARS-CoV-2 infection.

Exclusion Criteria:

• Men aged under 18 and over 45.
• Men who cannot produce a sperm sample by antegrade ejaculation.
