Abstract

A protein factor, spermatheca fraction fi fty, isolated from the spermatheca/ovotestis gland of a marine mollusc Telescopium telescopium by 50% ammonium sulphate precipitation was capable of inducing a capacitation and acrosome reaction of washed goat cauda epididymal spermatozoa in vitro. The effect of this isolated bio-active compound on goat sperm cells was comparable to heparin and concanavalinA. The number of acrosome reacted spermatozoa treated with heparin, concanavalinA and spermatheca fraction fifty increased steadily and signifi cantly (P<0.001) over the extended period of incubation. Observation concluded that spermatheca fraction fifty could be used for the evaluation of sperm plasmamembrane integrity and/or acrosomal integrity in vitro.
