Assisted Reproductive Technology (ART) includes in vitro fertilization-embryo transfer (IVF-ET), gamete intrafallopian transfer (GIFT), zygote intrafallopian transfer (ZIFT), and frozen embryo transfer (FET). These techniques also apply to oocyte donation and gestational carriers. Approximately 99 percent of ART cycles performed are IVF-ET. IVF-ET has helped many couples conceive successfully. ART may be recommended when other treatments (such as intrauterine insemination) have not been successful or when there is severe male factor infertility, severe endometriosis or tubal obstruction. Fertility therapy generates a wide range of emotions. Waiting, uncertainty, and the demands of treatment can lead to feelings of frustration, confusion, and resentment. We believe that the more you know about the tests and treatments, the less anxiety and concern you will feel about your condition. If you are going through this process with a partner, please review this information together. Most centers utilize a multi-disciplinary professional team. During your treatment cycle, many team members, in addition to your individual physician, will participate in your care. Advanced infertility procedures require time and energy, as well as an emotional and financial commitment. The entire staff should make every effort to provide you with personal and compassionate care in order to make this difficult time as comfortable and manageable as possible.
