TOPIC:
Create New Technologies for Contraception

Grand Challenges Explorations Round 4
September 2009

Roadblock:

In recent decades, there have been tremendous improvements in the reproductive health of men and women in the developing world. Nonetheless, many do not have access to health supplies and services that enable planning the number and timing of pregnancies, safe delivery of children, and management and treatment of sexually transmitted infections. It is estimated that 200 million women in developing countries have an unmet need for effective contraception even while family planning is one of the most cost effective ways to reduce maternal, infant and child mortality.

Sub-Saharan Africa and South Asia have the highest maternal and infant mortality and lowest use of contraception. Early marriage and childbearing before age 18 is also a serious public health problem in many countries, leading to increased maternal and newborn death and disability. Women, and even young girls, often have little choice in decisions related to sexual activity and any overt contraception is often unaccepted.


Barriers to Uptake:

Many in the developing world do not use contraception because current methods do not meet their needs. For those whose income is less than $2 per day, cost is an especially important issue. Intermenstrual bleeding, a side effect that can occur with hormonal contraceptives, is not acceptable in certain cultural contexts. Skilled health care workers are often unavailable in resource poor settings so self administration or options that allow for non-medical staff -- such as community health volunteers -- can increase access to new methods. Additional barriers for women arise from differing contraceptive needs depending on stage of life and childbearing desire, the need for a covert contraceptive and the need to easily reverse effects of the contraceptive. For men, the current modern forms of contraceptive are the condom and vasectomy, which are not accepted in many contexts. Overall, increasing contraceptive uptake will not only require increased supply in the developing world but a larger range of choices for women and men so that their specific needs can be met in an appropriate, safe, culturally sensitive and cost-effective manner.


What We Are Looking For:

The goal of this topic is to solicit novel and innovative approaches to preventing unintended pregnancy. We seek proposals that are "off the beaten track," daring in premise, and clearly different from the approaches currently being developed or employed. Technologies or approaches should enhance uptake, acceptability and provide for sustained use; enable or provide for low-cost solutions; promote effective delivery and administration of new solutions; and ensure or enhance safety.


Highly desirable attributes include:

• Methods that prevent unintended pregnancy in addition to acquisition of HIV and other sexually transmitted infections;

• Self-administration methods or methods that do not require medical workers to administer;

• Discreet use methods for women; 

• New concepts that translate into lower cost, affordability and ease of logistics in the management of contraceptive procurement and distribution;

• Simple adaptation of existing technologies with characteristics important to meeting unmet needs;

• Technologies that can be translated quickly into approved products;

• Contraceptive methods that inherently include other health or personal benefits that would increase their uptake and desirability.


A few of the many specific examples to be considered include:

• A novel method that works after ovulation;

• Novel methods that interfere with sperm delivery or function in the male or in the female genital tract or both;

• Novel non-hormonal contraceptive (as an alternative option to hormonal formulations);

• New concepts in barrier methods that are culturally acceptable;

• Barrier methods that are desirable to men; male contraceptives that are desirable to men;

• New, untried concepts for a safe, practical and reliable contraceptive using immunological methods; 

• New delivery mechanisms for short and long acting methods.


We will not consider funding for:

• Solutions that are not applicable to the developing world setting; 

•  Exclusively non-technological, social intervention;

• Technologies or solutions that are already mature in development.
