Information provided by (Responsible Party):
Ruth Bunker Lathi, Stanford University
  Purpose
We are examining whether pregnancy rates differ based on day of embryo transfer in patients who replace all available embryos after an In vitro Fertilization (IVF) cycle. Patients must be undergoing IVF treatment at Stanford University and patients will not receive compensation for their participation (no medical costs covered or patient payment for participation).

Condition Intervention
Infertility Procedure: Day 3 embryo transfer Procedure: Day 2 embryo transfer

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Embryo Transfer on Day 2 vs. Day 3 After Oocyte Retrieval in Patients Who Plan to Replace All Embryos After an In Vitro Fertilization Cycle

Further study details as provided by Ruth Bunker Lathi, Stanford University:

Primary Outcome Measures:
  • Pregnancy rates [ Time Frame: 1 year ]

Secondary Outcome Measures:
  • Live birth rates [ Time Frame: 1 year ]
  • Multiple gestation rates [ Time Frame: 1 year ]

Enrollment: 242
Study Start Date: January 2007
Study Completion Date: March 2009
Primary Completion Date: March 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Day 2 embryo transfer
Embryos are transferred 2 days after fertilization.
Procedure: Day 2 embryo transfer
Embryos are transferred 1 day prior to standard of care
Active Comparator: Day 3 embryo transfer
Standard of care for women undergoing IVF with a limited number of embryos is to transfer all embryos on Day 3 after fertilization
Procedure: Day 3 embryo transfer
Standard of care

Detailed Description:
The decision on the number of embryos to transfer after an IVF cycle is based on the number of available embryos, the quality of the embryos, the patient's age, and the goal of limiting multiple gestations. Stanford Fertility Center and most IVF centers examine the embryos on the third day after oocyte (egg) retrieval to select for the best quality embryos to transfer, and depending on quality, the remaining embryos are frozen to be used in the future. Patients with a limited number of embryos, those that plan to replace all available embryos after an IVF cycle, do not need to wait until the third day after oocyte retrieval to select embryos, and may replace the embryos on the second day after the oocyte retrieval. We are examining whether pregnancy rates differ among these patients based on the day of embryo transfer (Day 2 vs. Day3). Patients must be undergoing IVF treatment at Stanford University and patients will not receive compensation for their participation (no medical costs covered or patient payment for participation).
