SEMEN ANALYSIS AND ANTISPERM ANTIBODY

Evaluation of the fertilizing potential of sperm is an important proce dure in in vitro fertilization and embryo transfer (IVF-ET) clinic, in order to avoid performing invalid conventional IVF-ET or unnecessary intracytoplasmic sperm injection (ICSI). However, none of the standard semen parameters are reliable indices in predicting IVF outcome. The test examining sperm-zona interaction is the best present method, thou gh the short supply of the human zona component should be solved. IVF- ET treatment is useful for pregnancy in women having sperm immobilizin g antibodies because it avoids exposing sperms to antibodies that bloc k fertilization. ICSI should be used in immunologically infertile men diagnosed by specific method to demonstrate the in vivo exposure of sp erms to antisperm autoantibodies that block fertilization.
