Zusammenfassung:Seminal plasma hypersensitivity (SPH) presents with localized vaginal and/or systemic allergic symptoms on exposure to protein components of seminal plasma. Although the true incidence is unclear, it is a likely underdiagnosed but an important cause of vulvovaginitis and dyspareunia that affects women across the entire globe. Systemic SPH is likely elicited by an IgE-mediated reaction to seminal plasma proteins other than spermatozoa. Localized reactions are likely mediated by a non-IgE immunologic mechanism. The diagnosis of both conditions is made clinically. Clinical presentation typically involves local vaginal discomfort and/or systemic symptoms including urticaria, angioedema, wheezing, dyspnea, gastrointestinal symptoms, or frank anaphylaxis. In roughly half of cases of localized SPH, reactions occur after first-time intercourse. Use of a condom prevents reactions, which aids confirming a diagnosis. In addition to a detailed history, skin prick and/or serologic testing may assist in making the diagnosis. Both local and systemic SPH are managed by the use of barrier contraception or intravaginal graded desensitization. Although SPH has not been shown to directly cause infertility, it may make conception challenging due to the discomfort or systemic symptoms caused by unprotected vaginal intercourse. Data indicate that women with localized reactions have variable fertility outcomes, although the majority are able to have resolution of symptoms after desensitization and have normal term pregnancies. This review provides a step-by-step approach for evaluating and treating women with localized or systemic SPH.
