I'm just trying to understand this and hope my question makes sense. Could the increase in sperm count and motility somehow be an indicator of an autoimmune response? Thank you for your informative videos!

Immune response in immune privileged tissues is not a plausible explanation IMHO.

More plausible explanation of the sperm count decrease is effect of body temperature increase on sperm quality and quantity. It is well documented that common side effect of any vaccination, including C19, is fever. And it is well documented that fever or any temperature increase has an adverse effect on sperm count and motility.

How long do the effects of fever last, though?

Length of fever depends on each individual, because there is no identical immune system and consequently only unique immune responses to antigens. Therefore, it is better to stay focused on sperm instead of fever. Sperm are extremely sensitive to testicular overheating. Even short-term increase above optimal scrotal temperature decreases sperm quality and quantity over month or so (https://www.givelegacy.com/resources/fever-sperm-quality-and-fertility/)

I was asking about the effects of, not the length of, the fever.

Here is what was found in Pfizer's own documents (point 5)

ASA affects sperm motility, not count. Therefore, fever explanation is still plausible.

My question- This is a study done early in the vaccine rollout. In June 2021, the Covid vaccine was only available for the previous 3 months to those who were elderly, immunocompromised and with pre-existing conditions. Who were and what age were these studies done on? Next question- June 2021 is over 1 year ago, what about recent studies? There will be a greater, more diverse pool to choose from at this point (August 2022).

The second study was a few months ago.

This exact issue (antibodies against sperm) is being discussed in this session on Jonathan Jay Coueys latest podcast stream at approximately 2h 25 minutes https://www.twitch.tv/videos/1574419199

Reading in the title 'later rebound increase' it would have been nice to know what the original level was and and if the 'increased to 30 million/ml' was back to normal level or... if it was still way off the mark. However, just after googling normal/average sperm levels, isn't the 30 mil still a poor level? BTW the Gonzalez study link did not work.

Interesting & informative as always Dr.McM! Thanks.

Next serious study needs to be to check, if the sperms DNA has been affected/altered?
