Monozygotic triplet pregnancy following egg donation and transfer of single frozen-thawed embryo.

Dichorionic triplets following frozen-thawed poor-stage embryo transfer: a report of two cases and a review

BACKGROUND We describe two cases of dichorionic triplet pregnancy after a frozen-thawed poor-stage embryo transfer. A 39-year-old and a 41-year-old woman underwent ART treatment. The first patient underwent intracytoplasmic sperm injection (ICSI) at 34 years of age, and two frozen-thawed poor-stage embryos were transferred at 39 years of age with assisted hatching, resulting in a trichorionic t...

P-187: Poor Endometrium and Repeated IVF Failure: Is That Any Place for Modified Natural Cycle Frozen-Thawed Embryo Transfer?

Background: The objective of this study was to compare the pregnancy rate of Frozen-thawed Embryo Transfer (FET) on natural versus hormone replacement therapy (HRT) cycle endometrium, in patients with repeated IVF failure (RIF). Materials and Methods: In this observational study, the pregnancy rate after FET on natural endometrium in patients with RIF and previously poor endometrium (<7mm) on H...

Pregnancy rates of frozen embryos recovered during winter and summer in Sistani cows

During spring, summer and winter seasons, Sistani donor cows, with normal reproductive status, were superovulated and embryos were recovered non-surgically on day 7. Grade A blastocyst embryos were either transferred fresh (spring) or frozen (summer and winter). Recovered embryos during summer and winter were exposed to glycerol and frozen using conventional method. During spring season, recipi...

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

I-29: Luteal Phase Support in Frozen-Thawed Embryo Transfer Cycle

Cumulative pregnancy rate has been significantly increased since frozen-thawed embryo transfer was applied in ART cycles. This method has become an essential part of IVF/ICSI treatment. Luteal phase support has been proven to be associated with higher rate of live birth rate. Human chorionic gonadotropin (HCG), and progestrone have been successfully used for luteal phase support in ovarian stim...
