Abstract:
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a single-stranded RNA virus that causes many diseases such as respiratory diseases, cardiovascular diseases, and gastrointestinal diseases. Although it has been shown that the angiotensin-converting enzyme 2 receptor, which has a high affinity for the SARS-CoV-2 is mostly expressed in the lungs, it is also expressed especially in the cells of the testicular tissue. Although there are studies showing the effect of SARS-CoV-2 on spermatogenesis, the effects of COVID-19 on sperm count, motility, and morphology are still unclear. The aim of this study is to investigate changes in sperm quality in men who had recovered and never had COVID-19, therefore semen samples were analyzed from all individuals in the patient and control groups aged 20-50 years who agreed to participate in the study and voluntary in SBU Ministry of Health Adana City Training and Research Hospital. (Toros University Ethics Committee Decision Number: 1433, Date: April 15, 2021) (Adana Provincial Health Directorate Ethics Commission Decision dated May 27, 2021/5). Two groups were selected (100 men had and recovered from COVID-19, and 100 men never had COVID-19) spermiograms from both groups were analyzed in accordance with the World Health Organization standards. The sperm concentration of the COVID-19 negative group was significantly higher than those in the COVID-19 positive group. No statistically significant difference was detected between the groups for sperm motility and morphology. It was observed that men with COVID-19 had decreased sperm concentrations suggesting that COVID-19 may have a negative effect on male fertility. However, in the long term, more comprehensive studies with a large sample size are needed to understand better the changes in sperm concentration.
Insights
COVID-19 infection was linked to lower sperm concentration in recovered men compared to those who never had the virus. Further research is needed to understand long-term effects on male fertility.
Area of Science:
- Reproductive Medicine
- Virology
- Public Health
Background:
- Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) affects multiple organ systems.
- Angiotensin-converting enzyme 2 receptors, targeted by SARS-CoV-2, are present in testicular tissue.
- The impact of COVID-19 on male reproductive parameters like sperm count, motility, and morphology remains unclear.
Purpose of the Study:
- To investigate potential changes in sperm quality among men who recovered from COVID-19 compared to a control group without COVID-19.
- To assess the effects of COVID-19 on sperm concentration, motility, and morphology.
Main Methods:
- Semen samples were analyzed from two groups of men aged 20-50: 100 recovered from COVID-19 and 100 who never had COVID-19.
- Spermiograms were evaluated according to World Health Organization standards.
- Statistical analysis was performed to compare sperm parameters between the groups.
Main Results:
- Men who recovered from COVID-19 exhibited significantly lower sperm concentration compared to the COVID-19 negative control group.
- No statistically significant differences were found in sperm motility or morphology between the two groups.
- These findings suggest a potential negative impact of COVID-19 on male sperm concentration.
Conclusions:
- COVID-19 infection may negatively affect sperm concentration in men.
- Long-term, large-scale studies are necessary to fully elucidate the effects of COVID-19 on male fertility and sperm parameters.
