Background: Endometriosis is the most common condition underlying infertility in women. To increase the rate of pregnancy in women with endometriosis, embryo selection is performed during in vitro fertilization. This study aims to prove the effectiveness of embryo selection on the rate of pregnancy in a hospital in Jakarta. Methods: This is a cross sectional clinical epidemiology study, perform...

Besides the established selection criteria based on embryo morphology and blastomere number, new parameters for embryo viability are needed to improve the clinical outcome of IVF and more particular of elective single-embryo transfer. Genome-wide gene expression in cumulus cells was studied, since these cells surround the oocyte inside the follicle and therefore possibly reflect oocyte developm...

Although natural selection does not guarantee that organisms will increase in complexity as they evolve, it is apparent that the complexity of certain lineages, such as our own, has increased during evolution. Although we have an intuitive appreciation of biological complexity--often thinking in terms of morphological or behavioral complexity, or the variety of cell types in an organism--the te...

All birds studied thus far are able to store spermatozoa within their oviducts for periods that can vary from several days to weeks, depending upon the species. Turkeys have a relatively long storage period compared with chickens, an observation that leads to the suggestion that sperm residing within the oviduct may interact with sperm entering the oviduct from later inseminations. Multiple sou...

Sex selection for non-medical reasons is a major controversy in around the world. Here in this paper, we presented the ethical arguments about sex selection for non-medical reasons and discuss about them in Islamic context. Significant arguments about sex selection relate to sexism and sex discrimination, sex disproportion, human dignity, playing God, psychological pressure on unselected childr...

BACKGROUND The reduction of multiple pregnancies by using elective single embryo transfers (eSET) requires critical and careful selection of the embryo for transfer. The current study was undertaken to assess whether early cleavage could be used as a marker of embryo competence in eSET procedures. METHODS The study included analysis of 178 eSET procedures. All embryos were checked for early c...

background: many studies reported that follicle size has an essential role in developmental potential of oocytes. also, the brilliant cresyl blue (bcb) test is one of the most important criteria in selection of more competent oocytes. objective: selection of developmentally competent bovine oocytes. materials and methods: a total of 1730 bovine cumulus oocyte complexes (cocs) were recovered fro...

In vitro fertilization has been available for over 3 decades. Its use is becoming more widespread worldwide, and in the developed world, up to 5% of children have been born following IVF. It is estimated that over 5 million children have been conceived in vitro. In addition to giving hope to infertile couples to have their own family, in vitro fertilization has also introduced risks as well. Th...

Embryo evaluation and selection is fundamental in clinical IVF. Time-lapse follow-up of embryo development comprises undisturbed culture and the application of the visual information to support embryo evaluation. A meta-analysis of randomized controlled trials was carried out to study whether time-lapse monitoring with the prospective use of a morphokinetic algorithm for selection of embryos im...
