Endocannabinoids and Human Sperm Cells
N-acylethanolamides (NAEs) are naturally occurring signaling lipids consisting of amides and esters of long-chain polyunsaturated fatty acids. Usually they are present in a very small amounts in many mammalian tissues and cells, including human reproductive tracts and fluids. Recently, the presence of N-arachidonoylethanolamide (anandamide, AEA), the most characterised member of endocannabinoid...
متن کاملEndocannabinoids, sperm functions and energy metabolism.
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...
متن کاملEndocannabinoids as Markers of Sperm Quality: Hot Spots

The latest potential hazard in our modern lifestyle is the use of plant-derived cannabinoids present in hashis...
متن کاملEndocannabinoids, blood pressure and the human heart.
The effects of exogenous and endogenous cannabinoids on the cardiovascular system have been the focus of extensive research. The direct and indirect effects of cannabinoids on heart and blood vessels depend upon experimental conditions, animal species, and, in humans, clinical background. Cannabinoids decrease blood pressure in hypertensive rodents primarily because of decrease cardiac contract...
متن کاملHuman sperm cells swimming in micro-channels
The migratory abilities of motile human spermatozoa in vivo are essential for natural fertility, but it remains a mystery what properties distinguish the tens of cells which find an egg from the millions of cells ejaculated. To reach the site of fertilization, sperm must traverse narrow and convoluted channels, filled with viscous fluids. To elucidate individual and group behaviors that may occ...
