## Abstract Epididymal spermatozoa were maintained at 4Β°C during and after release from the epididymis to assess the effect of membrane fluidity on acquisition by the sperm of the ability to bind to zonae pellucidae of mouse eggs. The hypothesis to be tested was: If membrane fluidity is necessary f

## Abstract Sperm penetration of zonae and fertilization of mouse eggs in vitro was studied as a function of sperm concentration over the range 10^3^β10^6^ cells/ml. Maximal fertilization was obtained at 10^5^ sperm/ml with markedly reduced levels seen at lower concentrations. Eggs inseminated at l
## Abstract Washed ejaculated boar sperm and sperm from the cauda epididymis bind to the zona pellucida of fixed porcine eggs in large numbers. Sperm incubated in the presence of dextran sulfate (8 K daltons or 500 K daltons) or fucoidan and then washed no longer bind to eggs. Other acid carbohydra
