1.) There really is no credible information on lyme being passed by sexual transmission. We can rarely find it in the blood or bodily fluids with the best technology that exists on earth, so to think there is enough of it in the semen to cause infection doesnt really make sense, and even if it does happen, is likely to be very improbable.
not wishing to argue - but i'm not sure this is fair representation of what is known so far dcd - but there is some nuance involved
while its true that borrelia burgdorferi ( the spirochete that causes Lyme disease) are rarely found in the blood in any numbers, borrelia burgdorferi spirochetes are found in both the male ejaculate and in the female vaginal secretions pretty easily. I think there are a few studies on that.
quote from the 1st citation on MR's page on this
"Control subjects who were asymptomatic and seronegative for Bb had no detectable spirochetes in genital secretions by PCR analysis. In contrast, spirochetes were observed in cultures of genital secretions from 11 of 13 subjects diagnosed with Lyme disease, and motile spirochetes were detected in genital culture concentrates from 12 of 13 Lyme disease patients using light and darkfield microscopy."
there are also some limited scientific studies on sexual transmission in humans - and while not entirely conclusive either way - the weight of evidence appears to be more towards sexual transmission than against. for example if in female lyme patients, spirochetes can get from tissues into the vaginal fluid - then why could spirochetes not move the other way - from male ejaculate into vaginal fluid and into vaginal tissues and thereby infect the patient?
Dr MR has a page that does a reasonable job of presenting what we know in a fairly unbiased way
https://www.treatlyme.net/guide/can-lyme-be-sexually-transmitted-yes
the actual rate of transmission is unknown - largely because the studies simply have not been done - except for the small scale one mentioned in MR's page.
this is mainly for reasons of cost and lack of profit - but lack of evidence, because no one has found a way to profit from it yet, is not evidence of lack of transmission.
he also takes the view that transmission does not equal illness - and its more dependent on the health of the recipients immune system.
that's where i would focus
