The effects of Covid on fertility: what was discovered – RB
Last December a study coordinated by the Genk Institute for Fertility Technology, in Belgium, and published in the journal ‘ Fertiliy and Sterility ‘, investigated the presence of the virus in the spermatozoa of men tested positive and then cured. Here is what was discovered.
Could Covid affect fertility? The discovery
According to the study in question there would be no trace of the virus in the sperm of the healed men, but the motility and the sperm count could be compromised for at least 3 months. The research was conducted on 118 men between 18 and 70 years, infected during the first wave of the pandemic.
The results would have shown that, in the period immediately following the infection, the Rna of the virus was not present in the sperm of any of the study participants. Result confirmed at 53 days from infection. The motility and count of their spermatozoa, however, would have been significantly compromised in the short term, with the problem persisting for up to two months.
In detail, the motility average was reduced:
in 60% of men tested within 1 month; in 37% of men tested between 1 and 2 months; in 28% of men tested 2 months after the disease. As for the number of the spermatozoa , was reduced:
In the 37% of men tested within 1 month; in 29% of men tested between 1 and 2 months; in 6% of the sample examined over 2 months after infection. Overall, during the study period:
on 25, 4% of the men who contracted the virus were found to have few spermatozoa (oligozoospermia); the 44, 1% had a high percentage of poorly motile spermatozoa (asthenozoospermia); 67% had spermatozoa affected by some malformation (teratozoospermia). Only 24, 6% of participants had normal sperm parameters (from concentration to motility, up to morphology). More severe forms of infection were associated with a lower motility and morphology score, but having fever and other symptoms does not appear to affect sperm quality.
In summary, if it is true that there is no trace of the virus’ RNA in the sperm, the fact that the spermatozoa recorded a percentage point loss in motility and number suggests that the virus is able to overcome the blood-testicular barrier , a structure present in the seminiferous tubules, which hinders the passage of molecules between the basal and the adluminal compartment, a necessary condition for the normal functioning of the male genital system.
Does the vaccine cause infertility? The response of the ISS
About 6 months ago the Higher Institute of Health published a list of 12 fake news spread about the vaccine. One of these concerned precisely the hypothesis that the administration caused sterility or abortions. Nothing could be more false (among the ‘international’ hoaxes also that of the placebo to politicians instead of vaccines in Slovenia).
According to the ISS, in fact, to date there is no scientific evidence of a negative effect of vaccines on fertility , neither male nor female. Regarding the administration of the vaccine in pregnancy, the first observations, especially from the US data (where there are thousands of women immunized during gestation), did not reveal an increased risk of adverse effects for mothers and newborns.
For the Higher Institute of Health, in addition to the vaccine, not even the virus would cause sterility in people who contract it (here are the symptoms of the Omicron variant).
