[Ultrastructural aspects of the spermatozoon abnormalities on infertile men in Senegal].

Oligo-astheno-teratozoospermia being frequently observed (44,1%) in male subjects among hypofertiles couples of the sample population, we studied it at the ultrastuctural level. Our investigations have shown that, in addition to morphological and functional abnormalities, spermatic cells in said persons also presented serious ultrasructural disorders which would cause sterility. However in the absence of specific codified treatment for the majority of abnormalities found in sperms and given the high cost of the utrastructural analysis, we propose to limit our study to precise cases of male sterility through routine sample evaluations.
