The male birth control pill – A new approach to family planning and population control

Abstract

With the increase in the world's population, contraception is crucial in population control strategies. Majority of contraceptives produced today are targeted at women; many of whom experience side effects, leading to the discontinuation of these contraceptives after a year of use. As the use of condoms and vasectomies has been subjected to scrutiny, it is necessary for the development of male birth control (BC). Attempts to achieve this include hormonal and non-hormonal contraception. Hormonal contraception prevents the production of the sperm in the testes; but this mode of BC has been found to be ineffective while also causing behavioural changes in men. In contrast, non-hormonal male contraception focuses on rendering the sperm immotile to prevent fertilization post-copulation. Soluble adenylate cyclase is an area of research that has shown promise in this field. Furthermore, two inhibitors, TDI-10299 and TDI-11861, have been developed and tested, with the latter, showing greater potency and longer activity, in mice models. Overall, by developing non-hormonal male contraceptives, men will have more control over their reproductive health. Nonetheless, before such contraceptives can be made widely available, it is important that further research takes place to ensure the safety and effectiveness of these methods.
