Success rates with in vitro fertilization (IVF) continue to improve as we gain insight into optimal culture conditions for gametes and embryos. New procedures such as in vitro egg maturation, preimplantation genetic testing, single embryo transfer, and oocyte freezing hold the promise of reducing the cost, inconvenience, and risks of IVF, as well as preserving future fertility. We provide an ov...

BACKGROUND The development of the mouse zygote following fertilization in vitro in a KSOM-type medium containing either L-glutamine or glycyl-L-glutamine has been examined, and compared with the development of mouse zygotes produced by natural fertilization. METHODS Mouse IVF, embryo culture and embryo transfer. RESULTS Fertilization rates, development to the blastocyst stage, implantation ...

introduction: the aim of this study was to determine the effects of maternal age in fertilization rate of intracytoplasmic sperm injection comparison with ivf. material and methods: in this prospective clinical trial study, 200 couples with male subinfertility that referred to infertility clinic were enrolled. couples were selected on the basis of semen parameters and divided randomly into two ...

We present a Bayesian network model for predicting the outcome of in-vitro fertilization (IVF). The problem is characterized by a peculiar missingness process, and we propose a simple but effective averaging approach which improves parameter estimates compared to the traditional MAP estimation. The model can provide relevant insights to IVF experts.

One hundred thirty-five infertile patients were enrolled to investigate the efficacy of phloroglucinol-induced inhibition of the endometrial fundocervical wave and its effect on in vitro fertilization (IVF). We found that phloroglucinol significantly inhibited (P<0.05) peristaltic fundocervical wave, suggesting a feasible way of application of phloroglucinol to suppress endometrial waves during...

The aim of this prospective study was to evaluate whether couples with total fertilization failure in a previous in-vitro fertilization (IVF) attempt should be offered an additional IVF treatment with elevated insemination concentration or should be treated with intracytoplasmic sperm injection (ICSI). In 23 cycles 228 sibling metaphase II (MII) oocytes were randomly divided: 143 and 85 oocytes...

Background The aim of this study was to compare prenatal outcome of intra cytoplasmic sperm injection (ICSI) pregnancies with pregnancies obtained through in vitro fertilization (IVF). MaterialsAndMethods Retrospectively 532 pregnancies of ART cycles were assessed during 1999-2000. The main outcome measured including abortions, ectopic pregnancies, prematurity, low birth weight, cesarean sectio...

BACKGROUND Lifestyle factors including cigarette smoking, alcohol consumption and nutritional habits impact on health, wellness, and the risk of chronic diseases. In the areas of in-vitro fertilization (IVF) and pregnancy, lifestyle factors influence oocyte production, fertilization rates, pregnancy and pregnancy loss, while chronic, low-grade oxidative stress may underlie poor outcomes for som...

This is the first report implementing combined density gradient centrifugation/Zeta (DGC/Zeta) sperm selection procedure for a couple with eleven previous intra cytoplasmic sperm injection/ in vitro fertilization (ICSI/IVF) failure cycles. Semen analysis was carried out according to World Health Organization criteria. Protamine deficiency, DNA fragmentation and morphology were assessed by chrom...

Background Research on potential perinatal risk factors for asthma, has recently attracted considerable attention. Asthma could be associated with In vitro fertilization (IVF) via epigenetic modification of DNA by IVF drugs/hormones or via a genetic link of asthma with parental subfertility. Nevertheless, evidence of an asthma/IVF correlation is scarce and inconclusive. We therefore opted to ex...
