Sperm Allergy

Did you know that you can actually develop antibodies that will kill your own sperm? This can be experienced most commonly after a vasectomy, testicular torsion, infection, or trauma.

Do not worry for this is a solution with your sperm allergy! The possible solution is artificial insemination or assisted reproductive technologies (ART). About 20 to 40 percent of men impregnate their partner with this treatment. Immunosuppressive drugs such as cortisone and prednisone are sometimes used, but many doctors don't recommend them. Just talk to your doctor and get the best advice.
