A Pennsylvania couple discovered on their wedding night that the new bride was actually allergic to her new husband's sperm. They had been a couple for two years, but as the bride said, "before we were always very careful and used protection - this time we didn't". She felt sharp pains that would go on for weeks, then after numerous medical tests, they found out that the wife suffers from seminal plasma hypersensitivity, where her own body attacks the sperm and makes it inactive, while causing her pain as well.
