(CNN) –– The serious cases of covid-19 podrían affect the quality of the sperm of the males, which possibly impacts his fertility, following a new study published this year in the magazine Reproduction.
“This report is proportional to the primary evidence direct to the fact that the infection by covid-19 affects the quality of semen and the potential reproductive muscle,” the study concluded.
Prohibition of sins, experts who no participant and the investigation into the reaction immediately with skepticism about the conclusion of the information. Why should I try to generalize in excess of the results of the study.
«Debo hacer una fuerte nota de cautela in su interpretation of these dates. For example, authors claim that their data demonstrate that ‘covid-19 infection causes a significant deterrent to the male reproductive function’. But in reality only show must be an association “, warned Allan Pacey in an e-mail. Pacey is Professor of Andrology at the University of Sheffield in South Yorkshire, United Kingdom.
“Being sick of any virus, like the flu, can temporarily reduce the rate of spermatozoa (sometimes) during some weeks or months. It’s difficult to determine which part of the reductions observed in this specific covid-19 study will take place only in its presence, “said Dra. Channa Jayasena, also in an electronic mailbox. Jayasena started as a consultant in endocrinology and reproductive andrology at the Imperial College de Londres.
Además, «it is important to note that there is no evidence of covid-19 virus in the semen. There is also evidence that the virus can transmit semen through labor, ”said Alison Murdoch, director of the Newcastle Fertility Center and the International Center for Newcastle University in the United Kingdom.
A little study on fertility and covid-19
The investigation compared the edema of 105 fertile men without covid-19 met 84 fertile men diagnosed with the virus. In this sense, he analyzed his semen at intervals of 10 days during 60 days.
In comparison with healthy men without covid-19, the study found a significant increase in inflammation and oxidative stress in the sperm men with the virus. Its concentration, motility and form of spermatozoa have also been negatively affected by the virus.
The differences will increase with respect to the severity of the illness, the study found.
“These effects in spermatozoa are associated with a lower quality of spermatozoa and a reduced fertility potential. Although these effects tend to increase with time, they are significantly and abnormally higher altitudes in patients with covid-19. And the magnitude of these changes also relates to the pregnancy of the nurse “, said in a statement Behzad Hajizadeh Maleki, head of the investigator of the studio. Hajizadeh Maleki is a doctoral student at the Justus Liebig University of Giessen, Hesse, Germany.
También registers much higher levels of ACE2 enzymatic activity in men with covid-19, according to the investigation. The ACE2, the enzyme converter of angiotensin 2, is the protein that promotes the entry point for the new coronavirus to bind and infect an amplitude of human cells.
Sondeverbod, it is not surprising that covid-19 can affect the musculoskeletal system. It is said that the ACE2 receptors, the “same receptors that use the virus to access the pulmonary thighs, are also found in the testicles”, says Pacey, who is also the editor and chief of the Human Fertility Review.
A constant preoccupation
“Since the beginning of the covid-19 pandemic, there has been a compensable (theoretical) preoccupation with this coronavirus that could have a judicial impact on the fertility of men who become infected,” Pacey said.
Pacey has reviewed 14 published studies on the topic. It is therefore concluded that “any mediocre effect of coronavirus on male fertility is likely to be solely levy and temporal.”
In this sense, aggregate that the hallazgos of this studio, podrían deberse to other factors. For example, the use of drugs to treat the virus, which the authors also recognize in the study.
“For this reason, however, it is in this set of dates that its possible differences in the quality of sperm between men who have a fever (fever) and those who are well. “We know that a February fever can affect sperm production, independently of what causes it,” Pacey explained.
Sheena Lewis, Professor Emeritus at Queen’s University of Belfast in Ireland, shared similar thoughts on e-mail. “My preoccupation is that men with covid-19 teni a corporal weight more often and stand in a series of therapeutic treatments.
“We believe that obesity by itself reduces the quality of sperm. The treatments of covid-19 also pueden haber affected the quality of the sperm of these men. En lugar del covid-19 en sí », señaló Lewis.
“Because of this, studies are needed for more space. It’s antes that the testicles consider a specific organ of high risk of covid-19 », says Murdoch of Newcastle.
