The Oxytocin Receptor in Spermatozoa May Originate From Both Spermatogenesis and Epididymal Maturation, and Regulates Capacitation

open access: yesAndrology, Volume 14, Issue 3, Page 747-765, March 2026.
Abstract Background The oxytocin receptor (OR) is a G‐protein‐coupled receptor recently identified in human spermatozoa, whose origin and role in sperm physiology remain unknown. Objectives In this study, using the pig as a model, we examine the presence of the OR in ejaculated spermatozoa through immunofluorescence and immunoblotting, and investigate ...

Prevention of fertilization by exposure of hamster eggs to soluble acrosin [PDF]

open access: yes, 1977
Incubation of hamster eggs with trypsin or chymotrypsin, but not with a series of glycosidases or lipases, prevents capacitated spermatozoa from binding to the zona pellucida so that fertilization is prevented (Hartmann & Gwatkin, 1971; Gwatkin ...
