Krishnan A, Agwu JC, Kallappa C, et al. Development of central precocious puberty following cannabinoid use for paediatric epilepsy: causal or coincidence? BMJ Case Reports CP 2021;14:e239678.
Abstract
Research suggests a role for cannabidiol oil in managing certain forms of paediatric onset epilepsy. However, studies on the impact of cannabis on the hypothalamo-pituitary-gonadal (HPG) axis have conflicting results. Delta-9-tetrahydrocannabinol (Δ9-THC) acutely inhibits gonadotropin-releasing hormone in the hypothalamus, reducing testosterone levels by 65% in rhesus monkeys. Additionally, there have been reports of pubertal arrest and delayed puberty in male cannabis users. In contrast, other studies have reported higher testosterone levels following long-term cannabis use.
A 2-year-old boy presented with testicular enlargement, increased
penile length and growth of coarse pubic hair developing over 6 months. His
mother procured cannabidiol oil online, which he started taking 7 months
earlier for severe epilepsy refractory to medical management. Subsequent
investigations confirmed central precocious puberty. While it is unclear
whether the precocious puberty is a direct consequence of HPG axis activation
by Δ9-THC, this case demonstrates a temporal association between cannabis use
and development of precocious puberty.
