Seminal plasma hypersensitivity (SPH) is probably not a term you may have heard of before, but 20,000 to 40,000 women are affected by it in the US alone. It is effectively an allergy that causes all of the usual allergic side effects like hives, swelling, and potentially death. The trigger is specific proteins in semen.
That’s right; SPH is basically an allergy to semen.
In case you’re interested in an actual case of it, there is an article currently on ABC called: “Woman is Allergic to her Husband’s Sperm.”
What is fascinating to me is that the more I study sex and sexual issues, the more interesting things I find out and the more I think I’ve got a good handle on the entirety of the subject, the more I find that there is always more to learn.
