NCT00195559 ↗ Study Evaluating Combination of Levonorgestrel and Ethinyl Estradiol in Pre-Menstrual Dysphoric Disorder Completed Wyeth is now a wholly owned subsidiary of Pfizer Phase 3 2005-09-01 The purpose of this study is to determine whether Levonorgestrel/Ethinyl Estradiol (LNG/EE) is effective in treating the symptoms of severe Premenstrual Dysphoric Disorder.
NCT00204451 ↗ Human Ovarian Follicular Dynamics and Emergency Contraception Completed Canadian Institutes of Health Research (CIHR) Phase 4 2005-07-01 The researchers hypothesize that emergency contraception (EC) will initiate the changes associated with atresia or ovulatory failure at all stages of follicular development and that the image attributes associated with atresia will be similar regardless of the diameter of the dominant follicle when ovarian suppression is initiated. Second, changes associated with atresia may be observed, but ovulation of the dominant follicle is unimpeded.
NCT00204451 ↗ Human Ovarian Follicular Dynamics and Emergency Contraception Completed University of Saskatchewan Phase 4 2005-07-01 The researchers hypothesize that emergency contraception (EC) will initiate the changes associated with atresia or ovulatory failure at all stages of follicular development and that the image attributes associated with atresia will be similar regardless of the diameter of the dominant follicle when ovarian suppression is initiated. Second, changes associated with atresia may be observed, but ovulation of the dominant follicle is unimpeded.
