Immunology and male infertility.
This article has attempted to review evidence that suggests that immune factors may be operative in a small but significant number of infertile men. Although our current understanding of the possible processes by which autosensitization to previously sequestered reproductive antigens occurs is incomplete, there are laboratory assays presently available that give an indication, but do not prove, that immune factors may be contributing to the infertile state. Continued research is needed to develop new assays and more purified sperm antigens, which might enhance our knowledge of the underlying immunoreproductive changes. Until these are available, the following procedures should be considered when investigating a patient with infertility of suspected immune origin. The patient's history should be taken, and a physical examination should be performed. A complete blood count, urinalysis, and complete semen analysis and culture should be taken. Next, in vivo cervical tests (Sims-Huhner) are performed, followed by sperm antibody assessment (serum, semen) and perhaps in vitro cervical mucus sperm assays (especially the crossed hostility test). After the tests have been completed, the following possibe treatments exist: 1. Treatment of underlying infections 2. Correction of obstructions 3. Corticosteroid (or testosterone?) therapy 4. Washed sperm insemination 5. First portion of fresh ejaculate insemination 6. Artificial insemination with homologous donor 7. Adoption.
