简要总结
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.
详细描述
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.

入选标准
- •All men aged 18 to 45 having a sperm analysis done at the Fertilys fertility center in the last 2 years who have not contracted COVID-19, agreeing to participate in the study and having signed the consent form to participate in the study.
- •All men aged 18 to 45 having a sperm analysis done at the Fertilys fertility center in the last 2 years) who have contracted COVID-19 within the last 6 months, agreeing to participating in the study and having signed the consent form to participate in the study.
- •All men aged 18 to 45 years with a sperm concentration ≥ 15 million/mL, progressive motility ≥ 20% and a percentage of normal forms ≥ 2%.
排除标准
- •Men aged under 18 and over
- •Men who cannot produce a sperm sample by antegrade ejaculation.
- •Men whose sperm concentration is <15 million/mL, progressive motility <20% and a percentage of normal forms <2%, determined following the production of a "reference" sperm sample, carried out before March 2020, i.e. before the COVID-19 pandemic.
结局指标
主要结局
Viral RNA in seminal plasma
时间窗: Pre-infection, on the day of recruitment and six month later
The number of SARS-CoV-2 RNA copies and viral particles / mL of seminal plasma will be assessed
Changes in sperm parameters quality
时间窗: Pre-infection, on the day of recruitment and six month later
Sperm concentration and motility will be assessed using computer-assisted sperm analysis (CASA). Sperm vitality and morphology will be evaluated using eosine-nigrosine and Romanowsky staining techniques, respectively. DNA fragmentation and sperm chromatin decondensation will be measured using the Terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) and aniline blue assays, respectively. These sperm parameters will be compared before and after SARS-CoV-2 infection and between the different time frames.
