Frozen versus fresh embryo transfer in women with low prognosis for in vitro fertilisation treatment: pragmatic, multicentre, randomised controlled trial

British medical journal
Objective To test the hypothesis that a freeze-all strategy would increase the chance of live birth compared with fresh embryo transfer in women with low prognosis for in vitro fertilisation (IVF) treatment.

Combined treatment of prednisone and hydroxychloroquine may improve outcomes of frozen embryo transfer in antinuclear antibody-positive patients undergoing IVF/ICSI treatment

Lupus, 2021
Background The influence of anti-nuclear antibody (ANA) on induced ovulation was controversial, and the effect of prednisone plus hydroxychloroquine (HCQ) treatment on frozen embryo transfer outcomes of in-vitro fertilization (IVF) and intracytoplasmic ...

Frozen Embryo Transfer Preparation

2019
The 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.

Cycle regimens for frozen-thawed embryo transfer

2002
Pregnancy 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 ...

The role of timing in frozen embryo transfer

Fertility and Sterility, 2022
The process of implantation is characterized by a complex cross-talk between the endometrium and the blastocyst, with the endometrium only being receptive to implantation during a transient window of implantation of approximately 2-3 days during the midsecretory phase.

Fresh versus Frozen embryo transfer

2022
IVF (In Vitro Fertilization) treatment has been the hope of many women to achieve pregnancies and carrying home children for many years. ART (Assisted Reproduction Technology) has developed and produced a lot of ways and technical methods, through technology and genetics that have huge success impact in infertility.

Low progesterone levels on the day before natural cycle frozen embryo transfer are negatively associated with live birth rates.

Human Reproduction, 2020
STUDY QUESTION Are progesterone (P) levels on the day before natural cycle frozen embryo transfer (NC-FET) associated with live birth rate (LBR)? SUMMARY ANSWER Regular ovulatory women undergoing NC-FET with serum P levels 10 ng/ml.

The ART of frozen embryo transfer: back to nature!

Gynecological Endocrinology, 2020
The implementation of cryopreservation-techniques in the IVF laboratory and the improved survival rates of oocytes, cleavage and blastocyst stage embryos have led to a significant increase in the number of frozen-thawed embryo transfer cycles (FET). FETs

Higher probability of live-birth in high, but not normal, responders after first frozen-embryo transfer in a freeze-only cycle strategy compared to fresh-embryo transfer: a meta-analysis

Human Reproduction, 2019
STUDY QUESTION Does the outcome of the comparison of live birth rates between the first frozen embryo transfer (ET) (in a freeze-only cycles strategy, i.e.
