I’m An MD Suspended By Twitter For Tweeting A Link To A Scientific Article On COVID-19 Vaccine Lowering Sperm Counts

I’m An MD Suspended By Twitter For Tweeting A Link To A Scientific Article On COVID-19 Vaccine Lowering Sperm Counts

My suspension is yet another example of Twitter’s arbitrary, Lysenkoist breaches of informed public discourse on covid-19. The suspension must be reversed, and my account restored fully intact, immediately. Please take notice and intervene Elon Musk (@elonmusk).

I am a physician currently affiliated with the Brown University Center For Primary Care and Prevention, and was an Associate Professor of Medicine and Family Medicine at The Warren Alpert Medical School of Brown University from 1997 until June, 2021. My CV lists my many medical and scientific accomplishments.

Among other things, as a clinical trialist and epidemiologist, I designed and completed the largest randomized, controlled trial ever conducted in chronic kidney transplant recipients.  I have 115 scholarly, peer-reviewed publications focused on epidemiology and clinical trials. I have testified as an expert witness in lawsuits pertaining to the Covid-19 pandemic—specifically on vaccine and mask mandates—while researching and writing extensively on those subjects. I recently contributed to an amicus curiae brief to the United States Supreme Court for the covid-19 vaccine mandate case NFIB v. Dept. of Labor, OSHA, et al./Ohio v. Dept. of Labor, OSHA, et al. which was cited by the Washington Post .

Until this morning, I had a very active Twitter account with a large following through which I shared scientific information, as well as my personal views.

[Andrew Boston Twitter Banner As Of February 16, 2022]

 This morning (6/22/22) I awakened to learn that overnight Twitter had summarily and simultaneously locked, and then suspended my account for this “offending” tweet from Father’s Day, 6/19/22:

As of this writing, my Twitter account is suspended. I have received no response so far to my appeal.

The tweet in question contained data from a recent peer reviewed publication in the journal Andrology, with the eponymous title, “Covid-19 vaccination BNT162b2 temporarily impairs semen concentration and total motile count among semen donors”.

[Full article available at]

The Journal Andrology is highly respected and published through a joint effort of American and European scientific associations:

The study was a straightforward, serial analysis of young male Israeli semen donors evaluating the potential impact of Pfizer’s covid-19 mRNA vaccine on their sperm concentration (count), and related functional measures, 15-45 [Time 1],75-120 [T2], and over 150 days after [T3] vaccination.”

What did the investigators find?

Again, quoting their publication, verbatim, based upon what the authors defined, a priori, as the primary statistical analysis (i.e., “ [a] 1) generalized estimated equation model (GEE) was used for repeated measures analysis,” which is indeed the most appropriate method!):

 “sperm concentration was significantly lower due to decrease of -15.4% (confidence interval -25.5%–3.9%) compared to [Time zero/baseline] T0 (p=0.01). Moreover, [total motile count; how sperm moved] TMC percentage change reduction of 22.1% was significantly lower compared to T0 (confidence interval -35% – -6.6%, p=0.007) as well. Although concentration and TMC were reduced also on T3, these values did not reach statistical significance.”

If anything the text of my 6/19/22 tweet understated the evidence of a possible longer term, ~ 5-month follow-up decline, calling it a “rebound” when “concentration and TMC were reduced also on T3, [though] these values did not reach statistical significance.” In other words, the trend was toward a persistent decline, although it did not “reach statistical significance,” but may well have been evident, and “statistically significant,” merely by studying more subjects.

Finally, my offending tweet added the truthful observation that no data were presented on the effects of booster vaccinations, and asked whether boostering might cause another cycle of decline in the sperm counts and functional measures only studied in relation to the initial vaccination.

My suspension is yet another example of Twitter’s arbitrary, Lysenkoist breaches of informed public discourse on covid-19. The suspension must be reversed, and my account restored fully intact, immediately.

Please take notice and intervene Elon Musk (@elonmusk).

There’s nothing special about experts, but that would include disinformation experts.

I wouldn’t expect much from Twitter, considering how scientifically illiterate and just plain old-fashioned ignorant they are. The people running the content moderation areas are either dimwitted software engineers with zero training in biology (they think a woman can have a p*nis), or blind-as-a-bat attorneys with social perversion disorder who think that pedophilia is just another sexual orientation.

“Oh, it was a mistake.”

The information is getting out there… anyway.

What is called for is complete sperm count integrity. How do we know that these counts are accurate? Who is counting all this sperm? We need a complete audit with a paper trail. The administration’s two greatest sperm gatherers must be put in charge- Kamala Harris and Pete Buttigieg.

stevewhitemd | June 22, 2022 at 1:16 pm

This is why, as an academic physician-scientist myself, that I refuse to have a Twitter account. Never have, never will.

Inconvenient truths are against Twitter’s code of conduct, Mr. Bostom.

But thank you anyway for having the integrity to do so.

So twatter claims this guy is spreading “disinformation” which is the same as calling him a “liar” and impugning his professional reputation.

Isn’t that demonstrably false (in this case), and also damaging to his career?

Couldn’t he sue them for defamation and/or slander?

    GWB in reply to Paul. | June 22, 2022 at 4:31 pm

    That was my response before even reading the post. “So, are you suing for defamation?”
    This needs to happen every time Twitter claims you’re spreading disinformation. And demand BIG $$$$$$. Hurt them.

It would seem that Twitter is not a reliable nor venerable forum from which to share anything of value, consequence, or even truth.

Where’s Musk?

Why has the entire Left bought into protecting Covid Fake Vax or die trying?

    M Poppins in reply to Skip. | June 23, 2022 at 8:20 am

    The answer should be obvious. The “pandemic” was stage 1 of setting up a worldwide leftist dictatorship using obligatory “health passports” that include all one’s data. The easier to track every movement, and to cancel/delete dissidents.

They’re more afraid of facts than they are of deliberate lies.

Uncle Samuel | June 22, 2022 at 3:35 pm

My questions would be
– Is the vaccine induced reduction in sperm count permanent?
– Is the reduction fairly common or consistent across the male population?
– Are there other times and causes, such as a temporary illness, throughout life when a male’s sperm count is reduced temporarily – or is it always permanent or on a downward slope?

    Am Greatness is wrong, for a simple reason: ABIM cannot revoke a medical license, because they don’t issue medical licenses. The states do.

    ABIM certifies individuals who have completed required training and passed a board exam (full disclosure: I am ABIM certified in internal medicine and in pulmonary diseases). ABIM could, I suppose, revoke my certifications, but my medical license is with the state of Illinois and ABIM can’t touch that.

    I wish there was a way to contact the author of the AmGreatness piece (Debra Heine), but the website doesn’t offer that option, nor a way to comment.

The censors at Twitter are so smart that they can’t find their own asses using BOTH hands.

We have gone from putting men on the moon to judging people on 240 character posts.

B”H” I studied that issue (among others) as a 1st year MEng student in the mid 90s in my CEE597 Risk Analysis class at Cornell in the context of xenoestrogens US gov EPA risk models not capturing endocrine disruptors. [Note to Prof. Josephson you can check w Prof. Stedinger Prof. emeritus ]

See also 2017: .il fertility meta-study 1973-2011: Sperm concentration in West dropped by 50%+
“Sperm concentration of men in Western countries has dropped by more than 50 percent in less than 40 years and there is no evidence that the decline is leveling off, a team of international researchers warned, based on a new and comprehensive study.

“Given the importance of sperm counts for male fertility and human health, this study is an urgent wake-up call for researchers and health authorities around the world to investigate the causes of the sharp ongoing drop in sperm count, with the goal of prevention,” said Dr. Hagai Levine.

Levine, head of the Environmental Health Track at the Hebrew University-Hadassah Braun School of Public Health and Community Medicine in Jerusalem, led the study along with Dr. Shanna H. Swan, professor in New York’s Icahn School’s Department of Environmental Medicine and Public Health, assisted by researchers from Brazil, Denmark, Israel, Spain and the United States.

The findings have important public health implications. Sperm count is the best measure for male fertility, and the data shows that the proportion of the male population with sperm counts below the threshold for subfertility or infertility is increasing. In addition, recent studies have shown that reduced sperm count is also related to increased diseases and mortality among men, so the the ongoing “alarming” decline points to serious risks to male fertility and health, the researchers said.

The study also indicates that the rate of decline among Western men is not decreasing; in fact, the rate of increase was “steep and significant,” even when analysis was limited to those samples collected between 1996 and 2011. Concentration of sperm and sperm count are two parameters used to determine the quality of sperm in men.”

    Heck—the findings have serious geopolitical ramifications as well. If you cannot populate a country, you can’t defend it either.

    For that matter, if you can’t fertilize, you don’t have to worry about terminating a pregnancy. Which raises the question of abortion demographics, doesn’t it?

    There’s a movie about this: Children Of Men (which is not about what it sounds like it would be about). It’s about a dystopian world in which there has been a sudden cessation of pregnancies, no reason obvious.

    It’s pretty depressing, so if you’re prone to that, don’t watch it.

Have to ask: was Warren Alpert in any way related to Herb?
Because that would be kinda cool.

What would you expect?
Well, maybe Elon will wind up calling the shots one day.
But if you wish to speak the plain, obvious whole truth…
Forget Twitter.

What would he expect, going around and speaking the unbiased truth and citing real science?
On Twitter?

I realize this is kind of a subtle point but Elon hasn’t actually bought Twitter yet. Asking him to fix this is pretty pointless until he does.

I can’t help but wonder if you got on the COVID bandwagon in the beginning. So many people…including doctors…caved to the hoax initially, discarding their own good judgment. Have you been fighting the insane diktats from the get-go or did you go along for the early ride? If you did, you ceded your own autonomy and contributed to your own banning.

And our country’s destruction.

    M Poppins in reply to creeper. | June 23, 2022 at 8:23 am

    I’m not a doctor or anything like it – but I was outspoken against the hoax from the first minute of the first day.

Hmmm….is this yet another way globalists seek to reduce the population?
