NES/T Male Contraceptive Gel Clinical Trial - For Couples
At The Lundquist Institute at Harbor-UCLA, we are testing a possible new method for male contraception. The medication is a transparent gel (applied daily to the skin of the man's shoulders) that is designed to temporarily stop the production of sperm.

The medication contains the hormones Nestorone® and Testosterone. These hormones suppress the production of sperm to prevent the possibility of fathering a child. Nestorone has been tested and shown to be safe and effective at blocking the production of the male hormones needed to make sperm. The testosterone in the gel works by replacing the testosterone that is normally produced by the body. 

The study gel is being developed by The Population Council, a non-profit dedicated to reproductive health, in collaboration with the National Institute of Health’s Eunice Kennedy Shriver National Institute of Child Health and Human Development

There will be no cost to you and your partner for the study medication, study doctor’s time, or procedures related to this study. Compensation for your time is provided.
Trial Overview
This trial is designed for male and female couples to participate in together. The trial is 18-24 months in length and requires monthly visits for the male partner. These visits will be done on weekday mornings at our clinic on the Harbor-UCLA Medical Center Campus in Torrance, CA. Most visits last 1 hour. The female partner will have some in-clinic visits, although most visits can be done remotely.
The trial is divided into 4 stages:
Couples will meet with the research team at our clinic at the Harbor-UCLA Medical Center to review the study protocol. Male participants receive a physical exam, medical history, urine, blood, and semen analysis. Female participants provide a medical history and take a pregnancy test. Once all the results are in, couples will be notified whether or not they have qualified for the study. Those who are eligible can then choose to enroll in the trial. 
During the suppression stage of the trial, the male partner will start using the study medication, but the couple will continue to use another birth control method of their choice. Men will apply the NES/T Gel once a day and will come in for monthly appointments to have their sperm count checked. When the male's sperm count is low enough (less than 1 million/mL), couples will be able to move to the next stage of the trial. The suppression stage typically lasts about 3-4 months.
Once the male's sperm count has suppressed to a low enough level, couples will be able to move to the efficacy stage. During this 12 month period, couples will stop using any birth control method or medications other than the NES/T gel. The male partner will continue to come to the clinic for monthly visits, and the female partner will need to come in once every 3 months during this stage. The research team will continue to monitor the male's sperm count to ensure it is staying at the appropriate level throughout this stage of the trial. 
During the Recovery Stage, the male partner will stop using the NES/T Gel and the couple will resume another birth control method of their choice. The male partner will continue to have monthly appointments until his sperm count returns to a normal level. This typically takes 3-4 months. Once the male's sperm count has return to a normal level couples can exit the trial.
