Semen Allergies Are More Common Than Thought, Affecting Men Too

Semen allergies, specifically seminal plasma hypersensitivity (SPH), are more common than previously thought, affecting women and possibly men, with symptoms ranging from mild to severe. The allergy is caused by proteins in seminal plasma, mainly PSA, and can be diagnosed through history and testing. Treatments include antihistamines, desensitization, and IVF with washed sperm, but awareness remains low due to stigma and misdiagnosis.
