Population growth in the last century has raised important social and economic questions. Thus, current methods of fertility control have been under debate for a long period. Birth rates are essentially dependent on several environmental and social factors but women, who are great users of contraceptives, play a major role. Regulation of male fertility has been widely studied in recent years with the aim of developing a new male contraceptive for further inclusion of men’s choice in family planning. Based on the ancient people techniques to control the birth rates, natural products appeared as a promising source for the development of a male contraceptive. Over the years, many plants and their main constituents have been studied in the search for their antifertility properties. Interestingly, some antispermatogenic effects have been reported. Herein, we will discuss the antispermatogenic properties of some natural products. We propose to discuss specific targets and sites of action of the selected natural products. Despite the advances in this field in the last years, the molecular mechanisms by which natural products can control fertility, need to be disclosed to develop an effective, reversible and safe male contraceptive and avoid undesired toxicity in other organs. To date, no natural-based male contraceptive is available in the commercial market, mostly due to the difficulty in reversing the effects of these products in male fertility.
