Access to family planning – the ability to choose whether to have children, when and how many – has an impact on a multitude of issues, including poverty, education and maternal mortality. When women can space out their children, they are less likely to die in childbirth, and their families have more opportunities to make a living and send their children to school. But there are currently 225 million women without access to reliable family planning services, most of them in developing countries.

As part of our “Experts to Watch” series, we highlight nine people – from veterans to youth leaders – who are working to help bring family planning services to the women who need them, using research, policy and interventions to advance the sexual and reproductive health and rights (SRHR) of women and girls worldwide.

Robin Gorna

Robin Gorna is a co-lead of the She Decides movement that launched after President Donald Trump’s reinstatement of the Global Gag Rule, which blocks U.S. funding to any foreign organization that offers abortion services or advice. Her advocacy work focuses on SRHR, particularly in regard to women, children and adolescents. Previously, she was head of the Partnership for Maternal, Newborn & Child Health, and before that she established the Global AIDS Policy Team for the U.K. government’s Department for International Development. She then served as that department’s senior health and AIDS adviser in Southern Africa. She is on Twitter @RobinGorna.

A veteran public health physician with about 30 years of experience, she was previously head of the reproductive health program in the Federal Ministry of Health, where she focused on safe motherhood; family planning, including contraceptive logistic management; adolescent reproductive health; and gender issues.

Jessica Kakesa

Dr. Jessica Kakesa is a reproductive health coordinator at the International Rescue Committee focusing on the Democratic Republic of the Congo. Having witnessed first-hand the suffering of displaced women and children, as well as losing members of her own family due to health reasons she says stemmed from not being allowed to choose a family planning method, she now works to expand free access to comprehensive family planning across the eastern region of DRC, parts of which suffer from the highest rates of maternal mortality in the country. After several free clinics were set up in Tanganyika Province last year, 400 new clients were reached in June alone.
