Opioids and cannabinoids influence mobility of spermatozoids
Date:6/20/2008

This release is available in Spanish.

A PhD thesis from the University of the Basque Country has concluded that there are opioid and cannabinoid receptors in human sperm and that these influence the mobility of spermatozoid. The research by Mr Ekaitz Agirregoitia opens the door to more effective treatment of fertility problems.

Freshly released spermatozoids cannot achieve fertilisation, they must undergo some changes for this to occur. Amongst other, such changes take place due to receptors situated in the plasmatic membrane (the layer covering the cells) and opioid and cannabinoid receptors are two of these. On coming into contact with these, physiological reactions are generated in the body which are similar to, for example, sedation, analgesia and low blood pressure. Moreover, according to the research undertaken to date, both substances have an influence on the process of fertilisation. It is known that the consumption of external opiates (heroin, methadone) reduces the mobility of spermatozoids and that external cannabinoids (hachis) causes changes in the reproductive process. Also, the body itself generates internal opioids and cannabinoids, secreted to enable us withstand pain or stress situations, and it is also known that this phenomenon affects the reproduction process.

Despite all this being previously known, there has been no thorough study of the opioid and cannabinoid receptors in the human sperm such as this one, carried out by Mr Ekaitz Agirregoitia Marcos for his PhD thesis, defended at the Faculty of Medicine and Odontology of the University of the Basque Country (UPV/EHU) and entitled in Basque, Opioide-hartzaileak eta kannabinoide-hartzaileak giza espermatozoideetan espresatzen dira eta haien mugikortasunean eragiten dute (Opioid receptors and cannabinoid receptors are expressed in human spermatozoids a
