The Pfizer-BioNTech COVID-19 Shots Harm Sperm

Source: COVID Chronicles
Isn’t it great that new harms keep popping up as research into the safety of the COVID-19 ‘vaccines’ uses data from the public rollout to compensate for what should have been assessed properly and thoroughly prior to or during clinical trials?
A peer-reviewed paper has just been accepted for publication in the journal Andrology. This journal has an impact factor of 3.842, which is quite good considering it has such a specialized focus. This falls into the category of what I like to call the ‘meat and potato’ journals; they publish good solid science. I like these kinds of journals because they tend to be influenced less by advertising dollars.
The paper that I am referring to can be found here.
I found this paper to be interesting. First, the authors are clearly ‘pro-narrative’; to a point where there is an awful lot of inappropriate rhetoric. Rhetoric has no place in an objective scientific article and this aspect of the paper should never have survived the review process. Regardless of the clear bias of the authors in favour of the COVID-19 inoculations, the results of their study are extremely concerning.
The authors rightfully criticized earlier studies that were being used to support the idea that COVID-19 inoculations have no negative impact on male fertility. All these previous studies had major flaws, including but not limited to:
- Testing only a single timepoint post-inoculation.
- Testing based on in vitro fertilization where there is a quality control step that eliminates low-quality sperm. One wouldn’t expect to find problems if only the best performing specimens are selected.
- Very small numbers of samples.
One of the things that I really liked about the current study is that it used serial samples from sperm donors. Specifically, samples were obtained prior to ‘vaccination’ and at multiple time points after the ‘vaccine’ regimen was completed. This means that each person served as their own internal control, which is ideal. The Pfizer-BioNTech product was used. The authors of the paper confirmed that none of the donors had been diagnosed with COVID-19. As such, any effects could be attributed to the vaccine, not the disease caused by SARS-CoV-2.
By approximately three months after becoming ‘fully vaccinated’ (i.e., defined as having received two doses), this is what the data demonstrated (confirmed to be significant by multiple different statistical tests):
- “sperm concentration was significantly lower”. Specifically, it was reduced by 15.4%. Put another way, the sperm concentration was reduced by 12 million/mL of ejaculate.
- Worse, there was a “[total motile count] percentage change reduction of 22.1%”. This translated into there being 31.2 million fewer motile spermatozoa per ejaculate.
Two rules of thumb when it comes to male fertility are:
- The more sperm, the greater the chance of one of them getting into the egg.
- Getting to and entering the egg requires the sperm to be mobile.
As such, the findings of this paper are quite concerning in the context of male fertility.
The data also demonstrated that these defects in semen appeared to be largely resolved by the mean long-term follow-up time of approximately six months. Interestingly, this led the authors to promote the shots because, although there is short-term damage to sperm, it looks like it resolves long-term, at which point a man would be ‘in the clear’.
Unfortunately, this study was performed when ‘fully vaxxed’ meant two shots. The authors assumed one would be finished getting jabbed at that point. Now, many countries have or soon will have re-defined fully ‘vaccinated’ to mean three shots. Further, four doses and beyond are being strongly encouraged.
So, how is a male going to recover from the so-called ‘transient’ damage to their sperm if they keep getting dosed before recovery can occur?
Worse, no studies have been done looking into the consequences on male fertility beyond two doses. What if it exacerbates the problem and/or extends the length of the problem?
Since sperm donors were used in this study, those from whom the semen was sourced would be considered particularly ‘robust studs’ among the male population. Their samples have to meet stringent quality control standards to become enrolled into a sperm donor program. This means there is the potential for greater harm to the semen of males among the general population whose fertility potential may not be as high.
