BackgroundThe requirement for luteal phase support (LPS) in stimulated IVF cycles is well established, however drug choice, and route of administration and duration of use are not. This report evaluates patients’ preference and satisfaction by using either vaginal or intramuscular (IM) progesterone (P) supplementation for luteal phase support after in vitro fertilization and embryo transfer (IVF-ET).MethodsIt is a prospective cohort study done in a reproductive and infertility unit in a tertiary care hospital from March 2013 through February 2015 for four hundred and nine patients undergoing IVF-ET. Patients were allowed to choose either vaginal or IM P for LPS. Patient preference and satisfaction, as well as differences in clinical pregnancy rates between the two groups were assessed at one or two time points throughout the study.ResultsThere were no statistically significant differences in the patients’ characteristics and clinical outcomes between the two groups. There were 88 pregnancies (38.8%) among patients treated with vaginal p and 62 pregnancies (34%) among IM P patients. Average satisfaction score at the pregnancy test and ultrasound (U/S) visits was similar between both groups.ConclusionsPatients’ satisfaction and pregnancy rates were similar between vaginal and IM P supplementation.
