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

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

Zinc Supplementation during Pregnancy: A Randomized Controlled Trial

Zinc deficiency during pregnancy has been related to adverse pregnancy outcomes. However, the results of zinc-supplementation trials have not been consistent in improvement of pregnancies outcomes. This study was undertaken to investigate whether zinc supplementation was associated with pregnancy complications in Iranian women during the last 2 trimesters. It also assessed the anthropometric me...

Effect of foot reflexology on headache due to nitroglycerin injection: A randomized controlled clinical trial

Introduction: Infusion of nitroglycerin often causes side effects including headache in patients. Therefore, various methods are used for patients’ relief of headache. Foot reflexology can reduce patients’ pain and suffering. The aim of this study was to examine the effect of foot reflexology on the severity of headache caused by the infusion of nitroglycerin.  Methods: In this randomized tri...

In unselected patients, elective single embryo transfer prevents all multiples, but results in significantly lower pregnancy rates compared with double embryo transfer: a randomized controlled trial.

BACKGROUND Elective single embryo transfer (eSET) in a selected group of patients (i.e. young patients with at least one good quality embryo) reduces the number of multiple pregnancies in an IVF programme. However, the reduced overall multiple pregnancy rate (PR) is still unacceptably high. Therefore, a randomized controlled trial (RCT) was conducted comparing eSET and double embryo transfer (D...
