News: update on male contraception
It is time to offer men new, reliable, safe, effective and reversible options for delaying and spacing their children, so that they can share more of the responsibility for contraception with their partners. Indeed, striking changes in men’s attitudes show their increasing willingness to share contraceptive responsibility with their partner and avoid unintended fatherhood1,2.
Unmet needs in family planning remain a significant challenge worldwide. As a result, women continue to bear the burden of more than 85 million unplanned pregnancies and 48 million abortions each year3. Novel male contraceptives could play a meaningful role in averting unintended pregnancies especially in settings where novel methods can attract new contraceptive users4
Even though male reproductive health and contraception are essential to meet the needs of millions of men and their partners, research in this field is supported by a limited number of non- profit and public organizations. The pharmaceutical industry has focused on other investment priorities, and must be reminded that men are ready to share the responsibility of contraception and assume control of their fertility2. This shift is critically important when nearly half of all pregnancies world-wide are unintended.
Since the first Congress on Male Contraception organized by the International Consortium for Male Contraception (ICMC) in 2016, contraceptive methods for men are increasingly in demand with the need for new non-barrier methods becoming ever more evident. Since the Weimar Manifesto in 1997 and the First Paris Manifesto presented by the faculty panel on May 4, 2016 (now published in seven languages and available on the ICMC website5,6), renewed investment and focus is imperative.
Since 2016, progress has been made with
Moreover, the U.S. National Institutes of Health has issued new competitive applications to fund research and development of male contraceptives. Partnership and collaboration between government, industry, academia and non-profit organizations is essential to drive progress.
In 2018, the pharmaceutical industry should join hands with public and non-profit organizations to support global research on male hormonal and non-hormonal contraceptives. Hormonal methods likely will be ready for general use first; these may pave the way for non-hormonal methods and their acceptance by men, probably with the encouragement of their partners. The return on investment could be high, as surveys suggest that as many as 50% of men are ready to take a male contraceptive that is easy to use and is reversible, such as pills, implants or gels10. Utilization could be even higher if new methods were to bring additional health benefits both to men and to women, such as avoiding the side effects experienced by women with current hormonal methods.
It is now time for governments, health agencies and global policy makers to support research in male contraception as a high priority and to foster partnerships with the pharmaceutical industry, academic centers, and private philanthropic organizations to accelerate its development and introduction globally. Media also must highlight the needs of men and women and their interest in reproductive health and male contraception. Progress being made by global research centers should be accessible to the medical community, pharmaceutical partners and to the public when the latest state of the art in this field is presented. Since 2016, ICMC membership has grown and now represents 44 different countries. Furthermore, workshops organized by the ICMC and by other professional organizations at international meetings in andrology, gynecology and reproductive endocrinology have increased outreach to the medical community through presenting the latest scientific progress.
We call for action! It is “Time for Male Contraception” to benefit the health of both men and women, and the well-being of their families, communities and of our planet Earth.
