ACTA ENDOCRINOLOGICA (BUC)

The discovery of the cannabinoid receptors CB1 and CB2 in 1990 and 1993, respectively, as well as of the two main endocannabinoids, anandamide in 1992 and 2-arachidonylglycerol in 1995, was an important step in identifying the strongest homeostatic system in the human body, namely the endocannabinoid system. Ever since, research has highlighted the crucial part played by this system in all the reproduction stages: folliculogenesis, spermatogenesis, oogenesis, fecundation, transport of the egg through the fallopian tubes, blastocyte implantation and pregnancy progression, as well as its implications in the physiopathology of the reproductive system: in endometriosis, ectopic pregnancy, miscarriage, preeclampsia, endometrial cancer, polycystic ovary syndrome, ovarian cancer. A special attention must be paid to the phytocannabinoids, natural components originating especially from the Cannabis plant inflorescences, whose medical effects are wellestablished nowadays with also acting on the receptors of the endocannabinoid system. The most recent research mainly focuses on the reproductive dysfunctions and disorders of the reproductive tissues, respectively, through its action upon the endocannabinoid system. Medical cannabis is nowadays legalized in more and more countries all over the world. At the same time, recreational cannabis remains one of the most consumed drugs (in Romania the most consumed one by young adults). Therefore, it is mandatory for specialists in obstetrics and gynecology, endocrinology, public health, hygiene or for general practitioners, to permanently update their information on this subject.
