PG - 685-93 AB - BACKGROUND: To try to explain the infertility of chromosomal translocation carrier patients, we compared the expression of two markers of apoptosis in the sperm of patients and of fertile donors, and we studied the meiotic segregation in the ejaculated sperm of these translocation carriers. METHODS: Twenty semen samples of translocation carriers, [reciprocal (n=14) and Robertsonian translocations (n=6)], were compared with the semen samples of donors (n=20). Different tests were applied: annexin V binding assay; terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labelling (TUNEL); and fluorescence in situ hybridization (FISH). RESULTS: The annexin V binding assay in sperm of patients with chromosomal translocation (n=17) showed a significantly increased proportion of sperm with externalized phosphatidylserine (PS) than in the control group (n=20, P
