Minimally Invasive Embryo Transfer and Embryo Vitrification at the Optimal Embryo Stage in Rabbit Model

The Comparison Between the Pregnancy Outcome after Easy Embryo Transfer and Difficult Embryo Transfer

Background: The role of embryo transfer (ET) in the success of in vitro fertilization/intra cytoplasmic sperm injection treatment is not well understood. In the present study we classified ET technique as difficult and easy types according to certain strict criteria, and compared the pregnancy outcome of the two ET types. Methods: This study was performed retrospectively on 295 infertile patien...

The neglected morula/compact stage embryo transfer.

BACKGROUND This retrospective study analysed the outcomes of 339 embryo transfers on either day 3 (n = 97) or day 4 (n = 242), and proposed a grading system for morula/compact embryos. METHODS The morula/compact embryo grading was based on: (i) the proportion of blastomeres undergoing the compaction process; (ii) the morphology of the compacted multicellular mass; (iii) the embryo quality on ...

Comparison between Conventional Blind Embryo Transfer and Embryo Transfer Based on Previously Measured Uterine Length

The cleavage stage embryo.

A precise embryo quality evaluation is of paramount importance to sustain a successful in vitro fertilization (IVF) program. In most IVF clinics around the world, this quality assessment relies mainly on the morphological evaluation of cleavage stage embryos. Embryologists should be able to correlate the features observed at the optical microscope with the implantation potential of each particu...
