Astonishing results of cannabis in men with fertility problems

The astonishing result came as a big surprise to scientists measuring the sperm counts of more than 600 men from couples attending a fertility clinic. They expected cannabis to have a detrimental effect on sperm count and fertility.

US lead researcher Dr Jorge Chavarro, from the Harvard T.H. Chan School of Public Health in Boston, said: These unexpected findings highlight how little we know about the reproductive health effects of m*******a, and in fact of the health effects of m*******a in general. ‘Our results need to be interpreted with caution and they highlight the need to further study the health effects of m*******a use.’

Dr Feiby Nassan, another member of the Harvard team, said: ‘An equally plausible interpretation is that our findings could reflect the fact that men with higher testosterone levels are more likely to engage in risk-seeking behaviours, including smoking m*******a.’ This view was echoed by leading British expert Allan Pacey, Professor of Andrology at the University of Sheffield. He said: ‘As the authors point out, men with higher sperm concentrations are likely to have more testosterone in their bodies and thus may be more likely to smoke m*******a because simply they are willing to take more risks. ‘In conclusion, I am not convinced that this paper moves us any further forward in this debate. ‘Moreover, nor does it give support to any apparent fertility benefits of smoking m*******a. ‘In my opinion, this should be avoided at all costs in any couples trying to start a family.’
