An updated survey on the use of progesterone for luteal phase support in stimulated IVF cycles
Dear friends and colleagues,
Two years ago, we initiated the first survey among worldwide IVF units on luteal phase supplementation in stimulated IVF cycles. The results received gave us all some perspective on the way we translate evidence-based medicine into clinical practice. This first survey covered respondents from 84 IVF centers in 35 countries, representing 51,155 cycles per year.
Findings showed that vaginal progesterone alone was used for luteal phase supplementation in 64% of cycles. In another 16% of cycles, vaginal progesterone was used in combination with either intramuscular (15%) or oral progesterone (1%). As a single agent, intramuscular progesterone was used in 13% of cycles, oral progesterone in another 2%, and hCG was still used in 5% of cycles. Progesterone was administered until 10–12 weeks of gestation in 67% of cycles; in 22% of cycles, it was discontinued when fetal heart pulsations were detected, and in 12%, it was administered until the patient received a positive pregnancy test.
As this survey was performed 2 years ago, we wish to know if worldwide clinical practices have changed since then. Please assist us by completing the survey below. Your responses will benefit the international IVF community.
As survey administrators, we thank you for your support of this initiative.
