Seminal plasma anti-sperm antibodies and IVF: the effect of semen sample collection into 50% serum

A retrospective analysis was carried out which studied IVF results for couples in whom the male partner had anti-sperm antibodies in seminal plasma, as judged by a positive MAR test. Of the 59 couples studied over a total of 113 cycles, 30 had IVF semen samples collected into sterile, dry pots. Thirty-eight of the couples had samples collected in to medium containing 50% serum, and nine couples underwent separate treatment cycles with samples collected both dry and into 50% serum. The results demonstrate that the addition of serum to sample collection pots significantly improves the 0ocyte fertilization rate and is followed by a greater chance of conception for these couples.
