Synaptonemal complexes (SCs) of male fertility impairment were analysed in two patients. In case one, his testicular histology was normal and there were 20% abnormal pachytene spermatoeytes, showing unsynaptic and broken SCs. It resulted in spermatogensis with unbalanced chromosomes and pregnancy wastages. In case two, he had no sperms basically. G-banded chromosome analysis of lymphocytes showed normal chromosomal karyotype, but triple fragment, lateral element swelling and fragment breakages of SCs were observed in his spermatocytes. The mechanisms of infertility,impairment of fertility for the observed men were discussed in this paper.
