For seminal plasma‐allergic patients to achieve pregnancy, immunotherapy or artificial insemination is recommended. However, these modalities require complicated procedures. We recently treated a patient with human seminal plasma anaphylaxis who was successfully desensitized after intravaginal rush desensitization and became spontaneously pregnant. She had a healthy full‐term infant. With immunoblotting, we identified multiple allergens in her husband's seminal plasma, with molecular masses such as 100, 75, 65, 50, 40, 38, 33, 20, and 18 kDa, and the pattern of immunoblotting did not change after desensitization. We found not only specific antibodies to the seminal plasma of the patient's partner, but also common antibodies to both the partner's and the control specimen. Our results suggest that intravaginal desensitization might be an effective and convenient initial approach for patients who want to achieve pregnancy, and also confirm the presence of both the specific and shared common allergens in the seminal plasmas of the patient's partner and the control subject.
