Isolated teratozoospermia: a cause of male sterility in the era of ICSI?
Francavilla S, Cordeschi G, Pelliccione F, Bocchio M, Francavilla F. Francavilla S, et al. Front Biosci. 2007 Jan 1;12:69-88. doi: 10.2741/2049. Front Biosci. 2007. PMID: 17127284 Review.
Acephalic spermatozoa result from a head-neck defect due to a failure of migration of the tail anlagen and related centriole to the caudal pole of spermatids. An abnormal sperm centrosome function may explain the defective embryo cleavage after ICSI wi …
