IVF was the first of the ART techniques to be developed. The first birth was in 1978 in England. The procedure was pioneered by a Gynecologist and a Ph.D. (Drs. Steptoe and Edwards). Next came GIFT,...

In Vitro Fertilization Genetic Algorithm (IVF/GA) is a recently created algorithm that combine the concepts of Genetic Algorithm and In Vitro Fertilization. The IVF/GA has the aim to improve the performance of Genetic Algorithm with the addition of IVF-Inspired mechanisms that better exploit the information of individuals. The Multimensional Knapsack Problem (MKP) is a complex combinatorial pro...

Background: Although in vitro fertilization (IVF) has been found to bypass the inhibitory effect of high levels of antisperm antibodies on sperm motility, fertilization rates are reduced in approximately 40% of the attempts. In this study, we investigated the relationship between antisperm antibodies measured by the direct mixed agglutination reaction (MAR) and the fertilization rate in inferti...

introduction: semen parameters and specially sperm morphology is used for the assessment of semen sample and for the prediction of the fertilization. however there is semen samples with normal sperm morphology but with hidden sperm chromatin anomalies. since sperm morphology and chromatin anomalies reduce the fertilization rat independently, the purpose of this study is to consider the relation...

The aim of the study was to compare the parthenogenetic activation and in vitro fertilization (IVF) of in vitro matured caprine oocytes. A total of 881 cumulus-oocyte complexes (COC’s) were collected from 243 ovaries. Oocytes were matured in TCM-199 medium containing eCG (20 IU/ml), hCG (20 IUμg/ml), oestradiol-17β (1 μg/ml), BSA embryo tested (3 mg/ml) supplemented with 10% fetal bovine serum ...

Background Oxidative stress induced by cyclophosphamide (CP), as a chemotherapeutic agent, causes vulnerability of sperm and declining the fertility capacity. Then in this study the effect of crocin (saffron extract) on amelioration of these side effects was investigated. MaterialsAndMethods In this study 24 mice were divided in three groups (n=8). Control group received normal saline (0.2 ml/d...

Assisted reproductive technologies have generated a worldwide "reproductive revolution."' Latin America is no exception.2 Access to reproductive technology, and in vitro fertilization (IVF) in particular, can substantially benefit people's well-being. IVF is an assisted reproductive technology that involves fertilizing female eggs with sperm outside of a woman's body in a laboratory. In IVF, th...

The aim of this study was to investigate whether the sperm chromatin structure assay (SCSA) results after swim-up are related to fertilization rates, embryo quality and pregnancy rates following in vitro fertilization (IVF). A total of 223 couples undergoing IVF in our hospital from October 2008 to September 2009 were included in this study. Data on the IVF process and sperm chromatin structure...
