sperm antibodies

sperm antibodies

Any of a group of antibodies produced against four distinct components of spermatozoa (sperm cells). While sperm antibodies are linked to infertility, they do not cause a particular disease; they may be found in the circulation (either free or as immune complexes), in semen and/or attached to the sperm surface.
