IN SHORT: Posts on social media suggest that onions, eaten raw or drunk as a juice, are a potent aphrodisiac. But there is very little evidence to back up these claims.
“It helps increase libido and also strengthens the reproductive organs. Onions also increase the testosterone levels in the body and can help in increasing the sexual stamina,” a 27 April 2023 post reads.
Testosterone is a sex hormone that has a number of functions in the body, including the development of the penis and testes, sperm production, the size of muscles, the voice deepening during puberty, and the growth of facial and pubic hair.
The hormone is found in both men and women.
But can it be boosted by eating this rather smelly snack?
Little scientific evidence to back the claim
A small number of scientific studies have investigated the effect of onion juice on the production of testosterone in men as well as the “copulatory behaviour” and sperm production of male rats. But none found conclusive results to suggest eating or drinking raw onion as an aphrodisiac.
He told Africa Check that there was no scientific research that had proven that onion juice increased testosterone levels in the body or boosted sexual potency in men.
“No, there is no empirical evidence to support that,” he said.
