## Abstract Calcium was identified by a pyroantimonateβosmium fixation technique in ram spermatozoa undergoing a spontaneous acrosome reaction induced by incubation of diluted semen at 39Β°C. Intracellular calcium was only detected in diluted spermatozoa and increased in amount and distribution over
## Abstract When hamster spermatozoa were preincubated for 1β2 hr in Ca^2+^βcontaining medium and then exposed to lysolecithin (LC), large proportions of the spermatozoa underwent acrosome reactions within 15 min. These acrosomeβreacted spermatozoa were capable of fertilizing eggs. The earliest vis
## Abstract The acrosome of the mature spermatozoon functions as a regulated secretory vesicle which performs several critical functions in mammalian fertilization. Acrosome assembly occurs throughout spermiogenesis and continues during posttesticular sperm maturation in the epididymis, resulting i
