Infection with the SARS-CoV-2 virus may negatively impact semen quality, in keeping with a study on 30 males performed by researchers on the All India Institute of Medical Sciences.
The crew led by researchers at AIIMS Patna famous that COVID-19 can result in multiorgan injury by way of the angiotensin-converting enzyme-2 receptor (ACE2), plentiful in testicular tissue.
ACE2 acts because the receptor for the SARS-CoV-2 spike protein, by way of which the virus beneficial properties entry into the host cells.
However, little info is out there relating to the shedding of SARS-CoV-2 in semen — the thick, white fluid that accommodates sperm — and its impact on sperm formation and fertility potential.
The study, revealed in the Cureus Journal of Medical Science, investigated the presence of SARS-CoV-2 in the semen of COVID-19 males.
The researchers additionally analysed the impact of the illness on semen quality and sperm DNA fragmentation index, which displays the integrity of and the injury to the DNA, thereby detecting potential sperm injury.
Thirty COVID-19 male sufferers aged 19-45 registered to AIIMS Patna hospital participated in the study between October 2020 and April 2021.
“We performed a real-time reverse transcriptase check on all of the semen samples. Detailed semen evaluation, together with the sperm DNA fragmentation index, was completed at first sampling that’s throughout COVID-19,” the authors of the study stated.
“After 74 days of the primary sampling, we obtained the second sampling and repeated all of the exams,” they stated.
The study, together with researchers from AIIMS Managalagiri and AIIMS New Delhi, discovered that each one semen samples collected in the primary and second sampling examined with real-time reverse transcription-polymerase chain response (RT-PCR) had been detrimental for SARS-CoV-2.
In the primary sampling, semen quantity, vitality, complete motility, sperm focus, and complete sperm rely had been considerably decrease, the researchers stated.
In distinction, semen agglutination or formation of sperm heaps, head defect, DNA fragmentation index, liquefaction time, semen viscosity, and leukocytes or white blood cells, had been elevated.
Liquefaction time is a measure of the time it takes for the semen to show into liquid whereas viscosity is the thickness of the seminal fluid.
These outcomes had been reversed on the second sampling however to not the optimum degree, in keeping with the resaerchers.
The findings had been statistically vital suggesting “COVID-19 negatively impacts semen parameters, together with sperm DNA fragmentation index,” the authors famous.
“Although we couldn’t discover SARS-CoV-2 in the semen, the semen quality remained poor till the second sampling,” they stated.
The researchers famous that assisted reproductive know-how (ART) clinics and sperm banking services ought to take into account assessing the semen of COVID-19 contaminated males.
ART contains all fertility therapies in which both eggs or embryos are dealt with.
These clinics ought to exclude males with a constructive historical past of SARS-CoV-2 till their semen quality returns to regular, the researchers added.
