Sperm morphology was studied in hybrid mice of genotype (C57BL X C3H)F1 following treatment with specific cannabinoids. Mice were treated for 5 consecutive days with the specific cannabinoid; 35 days after the last treatment, epididymal sperm were scored in the light microscope and assessed in the scanning electron microscope. The animals treated with delta9-tetrahydrocannabinol (delta9-THC) and cannabinol (CBN) had a statistically higher incidence of abnormal sperm than the controls. The incidence of abnormal sperm in the animals treated with cannabidiol (CBD) was not statistically different from the control value. The relative toxicity of the cannabinoids in these studies was delta9-THC greater than CBN greater than CBD. Normal sperm have a smooth kidney-shaped head with a prominent hook; abnormal sperm have shapes which include heads without hooks, banana-shaped heads, amorphous heads and folded heads.
Many people often confuse CBD with THC (tetrahydrocannabinol), the component in cannabis plants responsible for psychoactive effects. This leads many to hold the belief that CBD can cause the same mind-altering effects. However, this is not the case.
The Effects on Your Sperm Count: Smoking Cannabis vs. Taking CBD
But is it the same for those who take CBD and other cannabinoids?
CBD is one of the 110 cannabinoids that are found in cannabis and hemp plants. It was first discovered in 1940 by Dr Dams and his research team at the University of Illinois.
