Comparison of Two Embryo Transfer Catheters in Patients Undergoing in Vitro Fertilization and Embryo Transfer
In-vitro fertilization (IVF) treatment involves development of multiple follicles following ovarian stimulation, oocyte retrieval and embryo transfer (ET). ET is the final and most crucial step of IVF treatment.
The ET catheter has to pass through the endocervical canal to go into the uterine cavity through the internal os. The endocervical canal may be filled up with mucus or blood. Embryos trapped in the mucus or blood after the passage of the endocervical canal may not be able to implant into the endometrium. Guardia™ Pro Protective ET catheter is designed to allow the safe passage of embryos through cervical mucus and blood as its outer sheath protects the embryo through entry and then opens in petals to further advance the inner catheter and gently place the embryo.
The hypothesis of this study is that the pregnancy rate is significantly higher after ET using protective ET catheters.
