I spent the five happiest years of my life in a morgue. As a forensic scientist in the Cleveland coroner’s office I analyzed gunshot residue on hands and clothing, hairs, fibers, paint, glass, DNA, blood and many other forms of trace evidence, as well as crime scenes. Now I'm a certified latent print examiner and CSI for a police department in Florida. I also write a series of forensic suspense novels, turning the day job into fiction. My books have been translated into six languages.
The coroner's or medical examiners office, or find a college with an anthropology major and ask one of the professors.
After I spent 10 years as a secretary, bored out of my mind. I always liked mysteries and I liked science, but I never really thought about putting them together until long after my first round at college.
I don't really watch any except the ones on the ID channel, and those are mostly about the investigation. But when they do mention forensic evidence, they're accurate.
I actually don't know how a DNA analyst tells human from animal DNA, but I don't think it's very difficult. We have an easy field test called Hexagon OBTI that can tell animal from human blood in a matter of minutes.

i don't know. It would be worth a try.
Because human bodies are in constant flux. Cells slough off, fluids wash out other fluids, but a stain on a piece of cloth doesn't change.
Unless he actually ejaculated in his underwear, I don't see why there would be sperm in underwear he simply wore. But maybe that's one of those questions about men I'd just rather not know! I'm also not sure that semen would go back into solution when re-wetted like sugar or salt. So it might be possible, for all I know, but you'd probably have to ask a serologist or DNA technician. I'm sorry I can't be more help.
