acrosinn.
/ˈakrəsɪn/, U.S. /ˈækrəs(ə)n/ Biochemistry.
An enzyme found in the acrosomes of mammalian spermatozoa, which is thought to facilitate penetration of the ovum at fertilization by digesting its outer glycoprotein coat.

1970 L. J. D. Zaneveld et al. in FEBS Lett. 11 345 The acrosome of the mammalian spermatozoon is a cap over the anterior end of the sperm head containing digestive enzymes... One of these enzymes..has been assigned the name acrosin.
1998 New Scientist 28 Mar. 15/1 Before a sperm cell is able to fertilise an egg, it must chew through the egg's casing with the help of an enzyme called acrosin.
2009 Biotech Week (Nexis) 16 Dec. 838 In the boar reproductive system, acrosin inhibitors are found in seminal plasma and on spermatozoa.
