Abstract

Anaphylactic sensitivity to her husband's seminal fluid occurred in a 46-year-old woman six weeks after a hysterectomy. Her husband was azoospermic as a result of an elective vasectomy. A pooled sample of his seminal fluid was used for skin and laboratory tests. Fractionating (Sephadex G 100) chromatography was also performed on his seminal fluid. The patient showed positive intracutaneous skin tests to his unfractionated seminal plasma and a Sephadex G100 fraction designated No. 3. This fraction was also passively transferable to a nonallergic volunteer and it stimulated histamine release from the patient's leukocytes. The dose-response effects of this fraction compared with unfractionated seminal plasma in these assays showed greater bioactivity. After informed consent was obtained, the patient was immunized to fraction 3 in a classic desensitization protocol. Two weeks after the final dose of immunotherapy, intercourse was performed without condoms in a medical facility and under the supervision of a physician. No adverse symptoms were experienced by the patient on this occasion. Regular and frequent sexual activity is required to maintain her tolerant state.
