Primary Outcome Measures:
  • Clinical Pregnancy rate [ Time Frame: 6-8 weeks after oocyte retrieval ]
  • Live birth rate [ Time Frame: After 37 weeks of gestational age ]

Secondary Outcome Measures:
  • Implantation rate [ Time Frame: 4 weeks after embryo transfer ]

Enrollment: 200
Study Start Date: July 2008
Study Completion Date: August 2010
Primary Completion Date: May 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Day 5 embryo transfer group
Embryo will transfer at blastocyst stage (day 5 after ovum pick up)
Procedure: Day 5 embryo transfer group
Embryo will transfer at blastocyst stage (day 5 after ovum pick up)

Detailed Description:

A total of 200 infertile women with at least two previous IVF failures will enroll in this prospective randomized clinical trial study and will randomly be divided into two groups. Random permuted blocks with a block size of 4 will be used to ensure randomization and complete allocation concealment.

The study protocol will be assessed by an independent institutional review board and Royan ethics committee.

Ovarian stimulation protocol will include the use of a GnRH agonist (Superfact; Aventis Pharma Deutshlan, Frankfurt, Germany) administered in the long (down-regulation) protocol and the subsequent addition of FSH (Gonal F, Sereno, Switzerland). Embryos will be initially cultured in G1.V5 medium) Vitrolife-Sweden)TM on day 1 and 2, being transferred from this medium to G2.V5 ) Vitrolife-Sweden)TM on day 3. Embryos will be transferred on day 5, depending on the degree of expansion of the blastocyst.

Main outcome measures will be implantation, clinical pregnancy and live birth rates.
