PURPOSE: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is transmitted primarily via respiratory droplets and enters host cells through angiotensin-converting enzyme 2 (ACE-2) receptors. ACE-2 receptors have been identified in many tissues including testes. The aim of the study has been to investigate the long-term effects of SARS-CoV-2 infection (COVID-19) and its relative treatment on male reproductive health. METHODS: Cross-sectional analysis has been performed on 49 recovered COVID-19 patients who had semen analysis prior to the COVID-19 pandemic. Those who had a recovery time lag of at least 3 months have been re-examined, and 29 eligible patients with no andrological problems have been enrolled in the study. Following a detailed physical examination and retrieval of medical history, the values of semen analysis and serum sex hormone parameters have been collected and compared before and after COVID-19 infection. The p value of <0.05 has been considered significant. RESULTS: The average age of the 29 patients has been 31.21 ± 5.48 (range: 18–41) years. Favipiravir has been co-administered with hydroxychloroquine in 17 patients, while the remaining 12 received favipiravir treatment without hydroxychloroquine. The average time between clinical recovery from COVID-19 and collection of semen has been 4.52 ± 1.36 (range: 3–8) months. Before and after COVID-19, serum follicle-stimulating hormone, luteinizing hormone, total testosterone, and prolactin levels, as well as all semen parameters, have been comparable. CONCLUSION: Our study demonstrated that COVID-19 and its treatment with favipiravir and hydroxychloroquine did not affect spermatogenesis and serum androgen levels in the long-term period. Further clinical studies with larger sample size are needed to confirm and support our findings.
