Cannabinoids, the main active components of marijuana, have been shown to exert different adverse effects on male reproduction both in vertebrates and invertebrates. The main effects of endocannabinoids, a particular group of endogenously produced cannabinoids, in sperm are the inhibition of motility, capacitation and acrosome reaction, all fundamental processes necessary for oocyte penetration, whose alteration leads to the inhibition of sperm fertilizing ability. These inhibitory effects are mediated by the direct action of endocannabinoids on sperm through the activation of the cannabinoid receptor subtype 1 that has been shown to be expressed in mature sperm. In many different cell types it has been demonstrated that endocannabinoids negatively influence mitochondrial activity. In the present paper it will be briefly reviewed the role of endocannabinoids, on sperm motility, capacitation and acrosome reaction with particular attention on the possible interference of endocannabinoids with sperm mitochondrial activity.

Abstract

Cannabinoids, the main active components of marijuana, have been shown to exert different adverse effects on male reproduction both in vertebrates and invertebrates. The main effects of endocannabinoids, a particular group of endogenously produced cannabinoids, in sperm are the inhibition of motility, capacitation and acrosome reaction, all fundamental processes necessary for oocyte penetration, whose alteration leads to the inhibition of sperm fertilizing ability. These inhibitory effects are mediated by the direct action of endocannabinoids on sperm through the activation of the cannabinoid receptor subtype 1 that has been shown to be expressed in mature sperm. In many different cell types it has been demonstrated that endocannabinoids negatively influence mitochondrial activity. In the present paper it will be briefly reviewed the role of endocannabinoids, on sperm motility, capacitation and acrosome reaction with particular attention on the possible interference of endocannabinoids with sperm mitochondrial activity.
