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 FET in subsequent natural ...

Ideal frozen embryo transfer regime
Current Opinion in Obstetrics & GynecologyPurpose of reviewThis 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 findingsWhile the artificial-FET cycle provides advantages in scheduling and ...

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 ...

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 ...

Hormone replacement versus natural frozen embryo transfer for euploid embryos
Archives of Gynecology and Obstetrics, 2019The goal of this study is to investigate hormone replacement (HR) versus natural frozen embryo transfer outcomes for euploid embryos.This is a retrospective cohort study at an academic medical center of patients undergoing in vitro fertilization with 24-chromosome day 5/6 preimplantation genetic testing for aneuploidies (PGT-A), from 2014 to 2018 using

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

[Study of the best embryo transfer strategy in frozen-thawed embryo transfer cycle].
Zhonghua yi xue za zhi, 2009To study the relationship of the number and quality of embryos transferred with clinical pregnancy rate and multiple pregnancy rate in frozen-thawed embryo transfer (FET) cycle.Retrospective analysis of the clinical data of 995 FET cycles. Patients were stratified as age < 35 or > or = 35, Both groups' clinical pregnancy rate and multiple pregnancy ...

Fresh Versus Frozen Embryo Transfer
2019The fresh embryo transfer has traditionally performed in vitro fertilization (IVF) since 1978. The first pregnancy following the transfer of a frozen-thawed human embryo was reported in 1983. Since then, the clinical value of embryo cryopreservation has steadily increased over the decades. Improvements in vitrification now make frozen embryo transfer a

[Impact on outcome of frozen-thawed embryo transfer by reducing numbers of transferred embryos].
Zhonghua fu chan ke za zhi, 2011To study the impact on pregnant outcome of reducing the number of embryos transferred from three to two in women at age less than 35 who received frozen-thawed embryo transfer (FET).The analysis was performed on 90 FET cycles (77 infertile couples, less than 35 years old) with slow-freezing/rapid-thawing method, including 48 cycles with two embryos ...
