We sought to examine current use of, and indications for, progesterone supplementation in the luteal phase of non-in vitro fertilization (non-IVF) infertility treatments among Obstetrician Gynaecologists (OB/GYN) compared to Reproductive Endocrinology and Infertility (REI) Subspecialists. Using a web-based survey, the practices of U.S. REI and OB/GYN physicians practicing infertility from 2014–2016 were assessed. The main outcome measures were frequency of use and indications for progesterone supplementation for luteal-phase support in non-IVF infertility treatments. Comparisons between physicians groups by indication and treatment type were performed using Chi-square and Fisher’s exact tests. Sixty-four REIs and 49 OB/GYNs completed the survey. One hundred per cent of REI and 73.5% of OB/GYN respondents prescribed progesterone for luteal-phase support as part of non-IVF infertility treatment. The majority of all respondents utilized progesterone supplementation for one or more indications in clomiphene citrate and letrozole treatment cycles. Treatment type was the primary decisional factor reported by REIs (56%) for prescription of luteal-phase progesterone support. Serum progesterone level was reported as the leading decisional factor for luteal-phase supplementation (66.7%) by OB/GYNs. Luteal-phase progesterone supplementation in non-IVF treatments appears common for both physician groups in the United States in spite of lack of evidence supporting its effectiveness.
