The Effect of Vaginal Speculum Type and Retention Time on Pregnancy Outcomes During The Embryo Transfer Process

Condition(s) studied

Investigational drug(s) / intervention(s)

Retention time of speculum: According to the randomization, the speculum can be extracted : 1. just after the transfer catheter is withdrawn 2. 60 seconds after the transfer catheter is withdrawn 3. 420 second (7 minutes) after the catheter is withdrawn

Study summary

Investigators aim to investigate possible affects of a speculum material and retention strategy on IVF pregnancy results. The study is planned as a prospective, randomized control trial. All of the clinical managements, including the embryo transfers, will be performed by the same gynecologist for homogeneity of the study. Only the cases with good implantation potentials are going to be included. Therefore, transfers with cleavage embryos and blastocysts rather than good and top quality will be excluded. All patients included to final statistical analysis will receive the same luteal support.

Eligibility

Primary outcome measure(s)

• Pregnacy rates — Beta-HCG test will be taken on the 12th day of the embryo transfer
