Corticosteroids for anti sperm antibodies
When these barriers of protection are breached, then the immune system can form antibodies against its own sperm. Some of these antisperm antibodies ASAs just float around in the bloodstream, while others can attach to the sperm itself. Usually ASAs are not clinically significant, and most men with them have no fertility problems. However, in a minority of men, these antibodies can cause problems with conceiving a child. In men who test positive for ASAs, there is currently no way to predict whether the antibodies are going to definitely cause fertility problems, other than their impact on standard semen parameters see below.
