BackgroundThe use of ultrasound to guide placement of the embryo during in vitro fertilisation (IVF) is important, but there are times where a good image cannot be obtained. Having a trained sonographer perform the ultrasound may therefore improve the success of embryo transfer.AimTo determine whether the routine use of a sonographer to guide embryo ...

A simplified method of timing frozen embryo transfers
American Journal of Obstetrics and Gynecology, 1995Our purpose was to compare a simple artificial hormone replacement regimen with two other protocols incorporating pituitary down-regulation with gonadotropin-releasing hormone agonist for frozen embryo transfers.We performed a retrospective analysis of pregnancy outcomes after 366 frozen embryo transfers timed by one of three hormone replacement ...

Frozen embryo transfer: the present practice and beyond
jbcpp, 2013Abstract Background: With the success of oocyte donation in vitro fertilization (IVF) in postmenopausal women, the importance of endometrial preparation became obvious. This appears also very crucial for achieving pregnancy after frozen embryo transfer (FET) after failed fresh IVF cycles and ...

Ideal frozen embryo transfer regime
Current Opinion in Obstetrics & GynecologyPurpose of review This review aims to compare evidence on four criteria (embryo implantation, obstetric outcomes, patient convenience, and IVF-unit efficiency) by analyzing published research on different endometrial preparation methods for frozen embryo transfer (FET). Recent findings

Cycle regimens for frozen-thawed embryo transfer
2002Pregnancy rates following frozen-thawed embryo transfer (FET) treatment have always been found to be lower than following embryo transfer using fresh embryos. Nevertheless, FET increases the (cumulative) pregnancy rate, reduces cost, is relatively simple to undertake and can be accomplished in a shorter time period compared to repeated 'fresh' cycles ...

Cervical transfer of deep frozen cattle embryos
Theriogenology, 1981Cattle blastocysts were collected from 29 donors 7-8 days after estrus and frozen and stored in liquid nitrogen up to several months. Two procedures were used for freezing and thawing: -- procedure A: slow cooling to -60 degrees C (0.3 degrees C/min to -60 degrees C) and slow thawing (12 degrees C/min); -- procedure B: slow cooling to -30 degrees C (0 ...

Progesterone supplementation in the frozen embryo transfer cycle
Current Opinion in Obstetrics & Gynecology, 2015Currently, different modalities with regard to endometrial preparation for frozen-thawed embryo transfer (FTET) are used, the natural and artificial cycles being the most common approaches. This review is aimed to update the current knowledge about progesterone supplementation in both types of protocols.Natural cycle-frozen-thawed embryo transfer (NC ...

Frozen Embryo Transfer Preparation
2019The increased use of embryo freezing has placed greater emphasis on techniques and protocols regarding frozen-thawed embryo transfer (FET). While no one method has emerged as the superior choice, the various strategies in use each have their own benefits as well as drawbacks.

Frozen Zygote Intrafallopian Transfer
Obstetrical & Gynecological Survey, 1994To assess whether frozen ET to the fallopian tube is a possible alternative for cryopreserved embryos.Fifty-four patients (mean age 35 years) participated, in which their embryos were cryopreserved in 1.5 M propanediol at the pronuclear or two-cell stage. Each patient then underwent a steroid replacement cycle consisting of oral micronized 17 beta-E2 2
