Onion juice: helps boost rats' testosterone, has pro-sexual effect
If Iranian animal studies are anything to go by, fresh onion juice increases testosterone concentrations in the blood. Jordanian researchers have confirmed their Iranian colleagues' findings and have gone a step further. They discovered that onion juice also has pro-sexual effects. In rats that is.
Study
The researchers made fresh onion juice every day using a juicer, and gave their lab animals 0.5 [AC0.5], 1 [AC1] or 2 ml [AC2] of the juice orally for 20 consecutive days. A control group received no onion juice [C].
The juice boosted the animals testosterone concentration. The optimal dose was 1 ml per day. The human equivalent of this dose would be about 0.64 ml per kg bodyweight per day.
A daily dose of 10 mg paroxetine for 20 days reduced the animals' testosterone level, but a daily 1 ml onion juice prevented this.
Results
The rats that had been given onion juice were also quicker to mount the females, which would suggest that their libido had increased.
So the good old onion Latin name Allium cepa really is a testosterone booster, the Jordanians conclude. Allium cepa may even help against impotence.
Conclusion
"The observed improvements in copulatory behavior resulting from administration of Allium cepa juice could be mostly attributed to increased serum testosterone levels in male rats. Nevertheless, future investigations that include clinical trials are warranted to substantiate these effects of onion juice in humans."
