This volume is the proceedings of International Symposium on Male Sterility for Motility Disorders in Paris, January 30-31, 1998. Internationally recognized faculty present the latest findings on male sterility for motility disorders including the etiology of immotile sperm; therapeutic possibilities for motility disorders; ICSI option for immotile sperm; testicular sperm: physiological and pathological aspects and sperm retrieval; conceptus quality in ICSI w testicular sperm and ethical problems of ART.
