Semen analysis and seminal plasma biochemistry in two brothers with familial reciprocal translocation 46,XY,t(8;9)(p10;p10) transmitted by the father

Here we report familial balanced translocation 46,XY,t(8;9) (p10;p10) inher ited by two brothers from the father. The first subject, 33 years old, was examined after 3 years of childless marriage. Semen analysis showed severe oligozoospermia, hypomotility and teratozoospermia. His brother, 29 years o ld, volunteered to join this study. He had not yet tried to start a family. Semen analysis showed dyspermia, but the condition was much less serious t han his brother's, In both subjects, the secretory function of the epididym is and the genital tract accessory glands did not seem to be affected by th is particular translocation, This case report highlights the importance of cytogenetic analysis in dealing with infertile patients suffering from seve re dyspermia apparently sine causa, This is particularly the case when cert ain Assisted Reproductive Technology (ART) programs are recommended, where natural selection of the sperm no longer takes place (e.g. ICSI), The possi ble risk of an increase in fetal chromosomal abnormalities would suggest ge netic counselling in all such situations.
