OBJECTIVE: To report progesterone (P4) use and activity restrictions after embryo transfer (ET).DESIGN: A questionnaire was mailed to 412 SART clinics.MATERIALS AND METHODS: The survey was completed by 152 REIs (37%). It included demographics (gender, age, clinic size, years in practice), progesterone (timing, route, duration) and rest protocols after ET (immediately, at home, resumption of intercourse).TableProgesterone and rest policies in US IVF programsWHEN IS PROGESTERONE STARTED?Within 24 hours of retrieval13890Greater than 24 hours after retrieval1610WHAT IS THE ROUTE OF PROGESTERONE ADMINISTRATION?IM only8454.5IM and Vaginal5032.4Vaginal only2012.9WHEN IS PROGESTERONE STOPPED?7weeks/with FCA26178-12 weeks11977IMMEDIATE REST AFTER TRANSFER30 min or less106691 hour3422OTHER RESTRICTIONS AFTER TRANSFER?None17111 day of rest69452 or more days of rest6844 Open table in a new tab CONCLUSIONS: Certain practice patterns prevail in U.S. IVF clinics regarding P4 use and rest after ET. The majority of REIs initiates IM P4 within 24 hours of retrieval and continue P4 supplementation to 10 weeks of pregnancy. Almost three fourths of REIs require 30 minutes to one hour of immediate rest after ET and 24 to 48 hours of decreased activity at home. While research studies have not determined the best methods for P4 use and rest protocols there is a general consensus among REIs in the US.
