A randomized controlled trial of prophylactic antibiotics (co-amoxiclav) prior to embryo transfer

A randomized controlled trial of prophylactic antibiotics (co-amoxiclav) prior to embryo transfer.

BACKGROUND Bacterial contamination of the transfer catheter during embryo transfer is associated with poor clinical outcomes. Antibiotics at the time of embryo transfer may improve outcomes. We evaluated the effect of co-amoxiclav on the rates of bacterial contamination of transfer catheters and clinical pregnancy. METHODS On the day of oocyte collection, 350 patients were randomized, with se...

Antibiotics prior to embryo transfer in ART.

BACKGROUND Embryo transfer (ET) involves the placement of one or more embryos into the uterine cavity, usually by passing a catheter through the cervical os. ET is the final step in an assisted reproductive technology (ART) cycle, where a woman has undergone controlled ovarian stimulation, egg retrieval and in vitro fertilisation of her eggs. Despite the transfer of high quality embryos, many E...

Effect of Progesterone Supplementation on Natural Frozen-Thawed Embryo Transfer Cycles: A Randomized Controlled Trial

Embryo Transfer with Controlled Injection Speed to Increase Pregnancy Rates: A Randomized Controlled Trial.

BACKGROUND/AIMS Catheter injection speed affects depth and placement of the embryo into the uterine cavity and is shown to be highly variable in, and between, subjects in a manually performed embryo transfer. In an effort to standardize the injection speed during embryo transfer, we developed an automated transfer pump: the pump-regulated embryo transfer (PRET) device. In this randomized contro...

Evaluation of Nifedipine Administration on Embryo Transfer Success Rate: a Randomized Clinical Trial

Background and Objective: In- vitro fertilization (IVF) is one of the approved treatment options for infertility. Despite many progresses in this field, its success rate is about 20 -25%. Utilization of drugs which suppress or decrease uterine smooth muscle contraction before embryo transfer, theoretically can improve fertility by increasing implantation rate. This study was designed to evaluat...
