Numerous published trials now document that the embryo transfer (ET) procedure has a huge impact on pregnancy and delivery rates after IVF (In Vitro Fertilization). To compare the ease of use (defined as the rate of successful atraumatic insertion) of different types of embryo transfer (ET) catheters. This prospective randomized unblinded controlled clinical trial is performed to determine if there is any difference in ease of use among 2 different catheters : Cook k-soft-5000, Cook K-JETS-551910-S. Inclusion criteria: patients \< / = 38 years of age, body mass index (BMI) between 18 and 28, at least one frozen-thawed blastocyst transferred. Exclusion criteria: ICSI (Intracytoplasmic Sperm Injection)-TESE (Testicular Sperm Extraction) IVF cycles. A number of 352 consecutive women undergoing embryo transfer will be selected for this prospective, randomized controlled trial. Two protocols for endometrial preparation will be used before frozen/thawed blastocyst transfer: the modified spontaneous protocol and the oral/transdermal preparation protocol. ET will be done with patient in lithotomy position, under ultrasound guidance. No anesthesia will be used for the procedure. 176 patients will be enrolled in this trial and randomized to enter one of the two catheter group.
