Ejaculated mammalian sperm must complete a final maturation, termed capacitation, before they can undergo acrosomal exocytosis and fertilize an egg. In human sperm, loss of sperm sterol is an obligatory, early event in capacitation. How sterol loss l

Ejaculated mammalian sperm must mature (capacitate) before they can undergo acrosomal exocytosis and fertilize an egg. Loss of sperm sterols is an early step in capacitation. Because sphingomyelin slows cholesterol efflux from other cells, the role o

Human sperm incubated in vitro gradually become capable of acrosome-reacting in response to the agonist, progesterone (P4). Loss of unesterified cholesterol is an obligatory step in the development of acrosomal responsiveness. These experiments teste

When incubated in vitro, human sperm gradually become capable of acrosome-reacting in response to the agonist progesterone. Loss of unesterified cholesterol is required for sperm to become responsive to progesterone, but how cholesterol regulates acr

Human sperm become responsive to inducers of the acrosome reaction when they are washed free of seminal plasma and incubated in an appropriate medium. Previous work has shown that cholesterol-enriched medium prevents sperm from becoming responsive to

Human sperm become responsive to inducers of the acrosome reaction if they are washed free of seminal plasma and incubated in an appropriate medium. We tested the hypothesis that sperm must lose cholesterol during incubation in order to become respon

Total acrosin activity and acrosomal status were determined before and after cryopreserving human spermatozoa. Three different cryopreservation protocols were used. Both acrosin activity and the incidence of intact acrosomes decreased during cryopres
