Effect of Malvaviscus conzattii flower extract on male fertility

Chronic administration of Malvaviscus conzattii (MCV) flower extract at a dose level of 800 mg/kg b.w. for 30 consecutive days in male rats significantly reduced sperm counts and motility together with histological changes in testes. Mating with these treated animals three weeks following the drug schedule proved to be consistently infertile.
