In vivo effects of Aspalathus linearis (rooibos) on male rat reproductive functions Opuwari CS1, Monsees TK. Department of Medical Biosciences, University of the Western Cape, Bellville, South Africa Aspalathus linearis (rooibos tea) may improve sperm function owing to its antioxidant properties. To test this hypothesis, male rats were given 2% or 5% rooibos tea for [...]
