Population Council Research that makes a difference

Projects

Development and Physiology of Leydig Cells (more)
Testosterone production by Leydig cells in the testis is the critical factor ensuring adequate sperm production and male fertility. Council researchers are identifying components that affect testosterone secretion and may offer new avenues for contraception and male hormone therapy.
(1/1998 - ongoing)
United States

Dual Health Benefits: Nestorone
Council scientists at the Center for Biomedical Research are developing safer and more effective long-acting contraceptives that have dual health benefits, using molecules with selective binding to hormone receptors, such as Nestorone®, a derivative of progesterone.
(1/2010 - ongoing)
France, United States

Dual Health Benefits: Ulipristal (more)
Council scientists at the Center for Biomedical Research are developing safer and more effective long-acting contraceptives that have dual health benefits, using molecules with selective binding to hormone receptors, such as ulipristal, a novel progesterone receptor modulator.
(1/2010 - ongoing)
United States

Emergency Contraceptive Potential of Products Under Development (more)
Many contraceptive products may have utility as emergency contraceptive methods; the Council is evaluating the potential of selected candidate products.
(1/2005 - ongoing)
United States

Female Hormone Therapy (more)
Research at the Center for Biomedical Research is part of the Council's ongoing efforts to evaluate the long-term safety of the progesterone receptor modulator CDB-2914 for hormone therapy.
(1/2001 - ongoing)
United States

MENT® (more)
Council researchers are working to develop methods of contraception for men that contain MENT®, a synthetic steroid that resembles testosterone
(1/2005 - ongoing)
Chile, Dominican Republic, Germany, United Kingdom, United States

Nestorone® (more)
Many of the products under development at the Council employ Nestorone, a versatile synthetic progestin similar to the natural hormone progesterone
(1/2005 - ongoing)
United States

Physiology of Sertoli Cells (more)
The goal of Council research on Sertoli cells is the development of safe, reversible male contraceptives.
(1/1995 - ongoing)
United States

Probing Studies in Male Contraception (more)
Council researchers are undertaking research that may lead to novel contraceptive methods for men.
(1/1995 - ongoing)
United States

Subdermal Implants for Men (more)
Studies have found that men are interested in taking more responsibility for family planning; an implant for men is the Council's lead product in male contraception.
(1/2005 - ongoing)
Chile, Dominican Republic, Germany, United Kingdom, United States

Transdermal Delivery Systems for Men (more)
Council research has demonstrated that MENT permeates the skin significantly better than two other androgens and is safe for further development as a hormone therapy method for men.
(1/2005 - ongoing)
Chile, United States

Transdermal Delivery Systems for Women: Contraceptive Gel (more)
Council scientists are developing a contraceptive gel that is absorbed through the skin.
(1/2005 - ongoing)
United States

Transdermal Delivery Systems for Women: Spray-on Contraceptive (more)
Council researchers are developing a transdermal spray-on contraceptive that makes use of the synthetic progestin Nestorone.
(1/2007 - ongoing)
Australia, United States

Assessing the Acceptability of the Progesterone Vaginal Ring in Sub-Saharan Africa (more)
To expand contraceptive options for women in sub-Saharan Africa we are evaluating the acceptability of the progesterone vaginal ring, a user-controlled contraceptive method for lactating women, and exploring strategies for how to introduce the new technology.
(10/2011 - 9/2014)
Kenya, Nigeria, Senegal

Facilitating Regulatory Approval of Multipurpose Prevention Technologies for Reproductive Health (more)
The Population Council is playing a central role in the US Agency for International Development’s effort to clarify and inform regulatory pathways for multipurpose prevention technologies.
(10/2010 - 9/2012)
United States

One-year Combination Vaginal Ring, Phase 3 Study (more)
The NES/EE vaginal ring is a user-controlled method that can be reused for one year.
(9/2005 - 6/2009)
Americas, Australia, Europe, United States

One-year Combination Vaginal Ring, Phase 2 Study (more)
The NES/EE vaginal ring is a user-controlled method that can be reused for one year.
(9/2005 - 11/2008)
Chile, Dominican Republic, Sweden, United States

CDB-2914 Intrauterine Delivery System (more)
Council biomedical researchers are developing an intrauterine contraceptive delivery system that releases a novel progesterone receptor modulator.
(1/2005 - 1/2007)
United States

Progesterone Ring for Lactating Women (more)
Council researchers developed a vaginal ring for lactating women that extends the contraceptive effectiveness of lactation.
(1/1985 - 1/2000)
