Summary

A reciprocal translocation t(5;Y) (p15.3;q11) is detected in an azoospermic male. The meiotic chromosomes, after Q.M. staining, indicate that the two parts of the Y join together, at the pachytene stage, in the sex vesicule, but not at the diakinesis.

Résumé

Une translocation réciproque équilibrée t(5;Y) (p15.3;q11) est observée chez un patient azoospermique. Les chromosomes méiotiques, apreès coloration par la moutarde de quinacrine, montrent que les deux segments de l'Y se rejoignent au stade pachytène, dans la vésicule sexuelle, alors qu'ils sont séparés lors de la diacinèse.
