Regarding the sperm, I do not think (and I am happy to be corrected by a medical professional here) that just because people with Klinefelter syndrome produce no sperm they produce no fluid. I think they can still ejaculate; it’s just a low or zero count.I don't know whether he's got it or not LAM, just thought it was interesting that another serial killer did.
From the reading, Klinefelter ranges from mild forms to severe so I'm not sure the baggies contents would mean a great deal.
In theory if Edwards was told this, it may be why he was so obsessed with his sperm that he kept it in baggies.
However, one thing that strikes me is that Klinefelter syndrome is usually accompanied by weaker muscles. Is that something that Edwards seemed to have? He looked like a pretty fit bloke in his younger years, although obviously I am only going on pictures and could be completely wrong on that.
Totally appreciate that you are just putting information out there; I’m just continuing the various trains of thought. I think it’s interesting as a possibility.
