What's SPH, an allergy that made Lithuanian woman infertile?
In a rare medical case, a 29-year-old woman from Lithuania was found to be allergic to her husband’s semen, an unusual condition. Tests confirmed that she had Seminal Plasma Hypersensitivity (SPH), a rare allergy where a woman’s body perceives sperm proteins as harmful and attacks them. SPH triggers severe reactions similar to those caused by peanuts or animal dander.
