Pomegranate juice has been shown to favour androgen activity in numerous studies and also prevent estrogenic activity in others.
An article by Türk et al. (2008)1 examined the effects of pomegranate consumption on sperm quality and testosterone levels. Four groups of rats were given varying concentrations of pomegranate juice mixed with distilled water. There was a clear trend; the higher the concentrated solutions, the more improved the sperm quality and motility was. The testosterone levels were, on average, 27% higher in the highest concentration group compared to the no-concentration group.
Another study by Adams et al. (2010)2 found that the compounds contained within pomegranate juice inhibited the conversion of testosterone into estrogen.
Mutary et al. (2020)3 studied the effects that pomegranate juice had on sexual behaviour, fertility and protective measures against aluminium exposure to male mice. Pomegranate juice showed huge increases in sperm motility and improved sexual behaviour alone. When combined with the destructive exposure of aluminium, pomegranate juice prevents testosterone levels from dropping as severely as without.
A study by Boroujeni et al. (2017) found that testosterone and sperm quality were significantly improved through pomegranate.
