A comparison of frozen-thawed embryo transfer protocols in 2920 single-blastocyst transfers

Archives of Gynecology and Obstetrics, 2022
To assess the effect of frozen-thawed embryo transfer (FET) protocol on live-birth rate (LBR) and clinical pregnancy rate (CPR), in single-vitrified-blastocyst transfer MATERIALS AND METHODS: Retrospective cohort study with FET of a single-blastocyst embryos (n = 2920 cycles) thawed 2013-2018.

Birth of a triplet after transfer of four frozen-thawed embryos

Fertility and Sterility, 1989
This is apparently the first triplet pregnancy after four freeze-thawed embryos that terminated in a birth of three healthy infants, with relatively good birth weights and uneventful follow-up.

Transfers of frozen—thawed human embryos in cycles stimulated by HMG

Human Reproduction, 1990
A total of 130 transfers of frozen-thawed (F-T) human embryos was carried out after moderate ovarian stimulation with human menopausal gonadotrophin (HMG). Embryos were replaced 3 days after the spontaneous luteinizing hormone (LH) surge or 4 days if ovulation was induced by human chorionic gonadotrophin (HCG).

The future of frozen-thawed embryo transfer in hormone replacement therapy cycles

Current Opinion in Obstetrics & Gynecology, 2023
Purpose of review This review focuses on the efficacy of letrozole stimulated frozen-thawed embryo transfer (FET) compared to hormone replacement therapy (HRT) FET in women with polycystic ovarian syndrome (PCOS) and/or oligo-anovulation. Further, obstetric and perinatal risks in HRT FET are summarized.

Clinical Study of Transport Fresh Embryo Frozen-thawed Embryo Transfer

Journal of Mammalian Ova Research, 2005
ABSTRACT We evaluated the clinical efficacy of the transport fresh embryo frozen-thawed embryo transfer method, whereby fresh embryos are transported from the satellite center for cryopreservation at the main ART center. In the Transport group (T group), surplus embryos from the satellite center were transported to the main ART center for frozen-thawed

Transfer of fresh and frozen-thawed rabbit embryos to produce live young

Experientia, 1985
Live rabbits for immunological experiments were produced by transfer of fresh or frozen-thawed embryos. The transfer of 505 fresh embryos and 55 frozen-thawed embryos resulted in 141 young born alive, 81 of which lived between several months and several years. The control group consisted of 55 litters from natural matings.

[Impact on outcome of frozen-thawed embryo transfer by reducing numbers of transferred embryos].

Zhonghua fu chan ke za zhi, 2012
To 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 ...
