Meiotic progression was disturbed in the 47, XYY patient. Representative images show (a) Leptotene, (b) Zygotene and (c) Pachytene spermatocytes immunostained for SYCP3 (Red), MLH1 (Green) and CREST (Blue). d An increase in leptotene and zygotene, and decrease in pachytene spermatocytes were observed in the 47, XYY patient. N, The number of cells analysed; *** P <0.001, chi-square test
