Use of ultrasound guidance during embryo transfer.
Dear Sir, Coroleu et al. recently reported that the use of ultrasound guidance during embryo transfer improves pregnancy rates after IVF (Coroleu et al., 2000). In their randomized clinical trial, the pregnancy rate was 50% after ultrasound guided transfer, versus 33% after transfer using the clinical touch. Although we want to stress the importance of randomized trials to document improvements...
متن کاملI-11: The Use of Oxygen Consumption for Oocyte and Embryo Selection
Assisted human reproduction is characterized by a high variability in results regarding pregnancy and birth rates. In fact, in a cohort of fertilized oocytes from the same stimulation cycle, the development rate varies drastically, even though produced at the same time and under similar conditions. This variability results in large differences in implantation potential of human embryos develope...
متن کاملUse of the Chick Embryo Model in Uveal Melanoma.
Animal models play a crucial role in basic and translational oncology research. Conventional rodent experiments, however, face ethical, practical and technical issues that limit their use. The chick embryo represents an accessible and economical in vivo model, which has long been used in developmental biology and for the study of angiogenesis. It is also a recognised xenograft model, and becaus...
متن کاملThe use of morphokinetics as a predictor of embryo implantation.
BACKGROUND Time-lapse observation presents an opportunity for optimizing embryo selection based on morphological grading as well as providing novel kinetic parameters, which may further improve accurate selection of viable embryos. The objective of this retrospective study was to identify the morphokinetic parameters specific to embryos that were capable of implanting. In order to compare a lar...
متن کاملHysteroscopic Subendometrial Embryo Delivery (SEED), Mechanical Embryo Implantation
Background A major hurdle to improved in vitro fertilization (IVF) success rate is defective endometrial receptivity and implantation. Various techniques have been advocated to increase implantation while reducing side effects. Currently, embryo transfer (ET) is performed blindly without direct visualization. As such, we sought to develop a technique utilizing a flexible minihysteroscope with a...
