To assess if the waist:hip ratio (WHR) is associated with the pregnancy rate (PR) in in-vitro fertilization (IVF) and embryo transfer, waist and hip girths, in addition to height, weight, body mass index (BMI), indications for IVF, PR and other related variables, were measured in 220 women undergoing IVF-embryo transfer. Three variables were significantly negatively associated with PR; high age...

Background Selecting the best embryo for transfer, with the highest chance of achieving a vital pregnancy, is a major goal in current in vitro fertilization (IVF) technology. The high rate of embryonic developmental arrest during IVF treatment is one of the limitations in achieving this goal. Chromosomal abnormalities are possibly linked with chromosomal arrest and selection against abnormal fe...

OBJECTIVE Regret after tubal ligation continues to be a problem. After tubal ligation, couples have the option of tubal surgery or in vitro fertilization (IVF). STUDY DESIGN Using decision analysis techniques, we compared cost-effectiveness of tubal reanastomosis by tubal type vs tubal surgery or in vitro fertilization (IVF) for 3 separate age groups of women: <35 years of age, 35 to 40 years...

Despite the development of in vitro fertilization (IVF) more than 30 years ago, the cost of treatment remains high. Furthermore, over the years, more sophisticated technologies and expensive medications have been introduced, making IVF increasingly inaccessible despite the increasing need. Globally, the option to undergo IVF is only available to a privileged few. In recent years, there has been...

background: effect of different doses of cysteamine on rate of in vitro maturation (ivm ) , in vitro fertilization (ivf ) and glutathione (gsh ) level was studied. metaphase ii (mii) spindle area was analyzed for quantification of shape and size of oocytes.   methods: female mice were primed with 5 iu of pregnant mare’s stimulating gonadotrophin . germinal vesicle (gv ) oocytes were retrieved 4...

Mammalian fertilization comprises sperm migration through the female reproductive tract, biochemical and morphological changes to sperm, and sperm-egg interaction in the oviduct. Recent gene knockout approaches in mice have revealed that many factors previously considered important for fertilization are largely dispensable, or if they are essential, they have an unexpected function. These resul...

objective: retinoids are recognized as important regulators of cell differention and tissue function. previous studies, performed both in vivo and in vitro, indicate that retinoids influence several reproductive events. in this study, we investigated the effect of all-trans retinoic acid (t-ra) on maturation and fertilization rate of immature oocytes (germinal vesicle). materials and methods: g...

Background: This study was carried out to assess the effects of MnTBAP, a cell permeable antioxidant, on motility, membrane integrity, capacitation status and in vitro fertilization ability of frozen-thawed ram semen. Materials and Methods: Fresh semen ejaculates were collected with artificial vagina from five rams, mixed and divided into five equal fractions, and diluted (1:20 v/v) with commer...

This essay seeks to address a puzzling element of the current political and legal struggles over abortion in the United States: if, as pro-life activists insist, embryos are morally equivalent to living persons, then why do these activists not oppose in vitro fertilization (IVF) as aggressively as they oppose abortion? IVF accounts for a significant number of destroyed embryos. Constitutionally...
