Evaluation of arachidonic acid supplementation in the extender on the integrity of the acrosome membrane in post-freezing goat semen

Abstract

A possible explanation for the lower values after the addition of 50μM arachidonic acid would be its excessive concentration, considering that arachidonic acid, through the action of cyclooxygenase, is converted into prostaglandin E2, inducing the influx of Ca2+ through the membrane. sperm, leading to membrane fusion. It is concluded that the addition of 0.5μM and 5μM of arachidonic acid to the extender maintained the integrity of the acrosome membrane in post-cryopreservation goat semen, being beneficial for the process of sperm capacitation and fertilization, suggesting further research aiming at a greater accuracy of the concentrations of arachidonic acid as an antioxidant.
