The study is 14 months long with weekly to monthly visits. The subjects will be placed on the estrogen patch for the duration of the study. They will also be given weekly injections of testosterone or placebo for 6 months. During the testosterone treatment phase the women will be separated into 5 groups. The groups include a dose of testosterone that is very low, low, medium, high and placebo. A placebo looks and feels similar to testosterone; however it does not have testosterone in it. We use this to test if the subject is having a response to the testosterone itself or the thought of receiving testosterone. Neither the subject nor the investigators will know the dose until the end of the study.
