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...

Background: Embryo cryopreservation is an important part of assisted reproductive technologies to increase cumulative pregnancy rate in clients. However, clinical settings, embryos can be subjected repeated cryopreservation-warming cycles due certain circumstances. There are limited data on the effect such may have success embryo transfer procedures. In this study, we investigated cleavage-stag...

OBJECTIVE To compare the effectiveness of elective single embryo transfer versus double embryo transfer on the outcomes of live birth, multiple live birth, miscarriage, preterm birth, term singleton birth, and low birth weight after fresh embryo transfer, and on the outcomes of cumulative live birth and multiple live birth after fresh and frozen embryo transfers. DESIGN One stage meta-analysi...

Traditionally, IVF success rates have been reported in terms of live birth per fresh cycle or embryo transfer. With the increasing use of embryo freezing and thawing it is essential that we report not only outcomes following fresh but also those after frozen embryo transfer as a complete measure of success of an IVF treatment. Most people agree that an individual's chance of having a baby follo...

BACKGROUND Single embryo transfer (SET) after IVF/ICSI has been shown to result in an acceptable pregnancy rate in selected subjects. In our unit, SET is routinely carried out among women under the age of 36 in the first or second treatment cycle when a top-quality embryo is available. In order to define further the selection criteria for SET, we have analysed the outcome of elective SET (eSET)...

Background: One of the main problems in ART is low pregnancy rates. The factors involved in successful pregnancy include; 1. mother related factors such as the status of endometrial receptivity and hormonal status of the mother. 2. embryo related factors such as; number of transferred embryo, embryo scores including: number and size of the blastomeres, and their fragmentation. The aim of the pr...

BACKGROUND Although elective single embryo transfer (eSET) minimizes the multiple birth rate after in vitro fertilization (IVF)/intra cytoplasmic sperm injection (ICSI), there remain concerns in many countries that it is less effective and more expensive than conventional double embryo transfer (DET). METHODS We compared the clinical outcome achieved in the years 1995-1999, in which eSET was ...

Embryo quality is a key determinant of the success IVF. Although focus has been on selecting best embryo for transfer, classification low-grade blastocysts (LGB) in existing scoring systems received less attention. This worrisome; freezing allows optimal use all created embryos, thus maximizing cumulative live birth rate, which arguably most important outcome infertile couples. A PubMed search ...

BACKGROUND It is known that experience of a previous crash is related to incidence of future crashes in a cohort of New Zealand cyclists. This paper investigated if the strength of such association differed by crash involvement propensity and by the need for medical care in the previous crash. METHODS The Taupo Bicycle Study involved 2590 adult cyclists recruited in 2006 and followed over a m...

introduction: the aim of this study was to evaluate the effect of sperm protamine deficiency on fertilization and embryo development post icsi. material and methods: semen samples from 27 patients candidate for icsi were assessed for semen parameters. sperm processing was carried out using pure sperm and percentage of protamine deficient sperm was assessed by chromomycin a3 post processing. cor...
