## Abstract Motile spermatozoa with lifted or absent acrosomal caps (“reacted acrosomes”) were observed by phase contrast microscopy exclusively in the oviduct of the rabbit reproductive tract during the first 16 hours __post coitum__ (p.c.). They were first identified at six hours p.c. in flushing

✦ Synopsis
Abstract
Acrosomal proteinase was found to be present in a highly organized distribution within the acrosomes of rabbit spermatozoa by cytochemistry. This distribution consists of at least six linear loops of evenly spaced proteinase granules, which run diagonally across the flat side of the sperm head in a criss‐crossing pattern with the two most anterior loops surrounding the region of the acrosome reaction. This is the first description of an organized distribution of enzymes within a lysosome‐like organelle.

## Abstract In spermatozoa, voltage‐dependent calcium channels (VDCC) have been involved in different cellular functions like acrosome reaction (AR) and sperm motility. Multiple types of VDCC are present and their relative contribution is still a matter of debate. Based mostly on pharmacological st
The aim of this study was to investigate the effect of an internal calcium ATPase inhibitor, TBQ, on human sperm capacitation and the acrosome reaction during incubation in a calcium-depleted media. Sperm were isolated into and incubated for up to 6 hr in media depleted of Ca 2+ and two Ca 2+ -conta
