background: our study compares the efficacy of the combined contraceptive vaginal ring to oral contraceptive pills (ocps) for hypothalamic-pituitary-ovarian (hpo) axis suppression in egg donor in vitro fertilization (ivf) cycles. methods: our retrospective cohort study includes patients from the center for assisted reproduction (care) in bedford, texas undergoing ivf cycles as egg donors from j...

Background One the main aspects of an in vitro fertilization (IVF) cycle is to avoid any possible systemic damage to women undergoing to a controlled ovarian hyperstimulation (COH). The aim of this work is to evaluate renal and hepatic function blood tests in patients undergoing controlled ovarian hyperstimulation during IVF cycles. MaterialsAndMethods All patients received a long stimulation p...

In women undergoing in vitro fertilization (IVF) who have an implantation failure (IF) after repeated embryo transfer, an association with the presence of acquired thrombophilia has been demonstrated, and a thromboprophylaxis seems to be efficacious in improving implantation rate. More recently a role inherited trombophilia has been recognised to have a role in recurrent otherwhise unexplained ...

In vitro fertilisation (IVF) has become a useful breeding tool in most of the developed world. In this paper the success of bovine IVF and the birth of live calves under typical South African conditions is reported. Oocytes for IVF were collected from the ovaries of 6 slaughtered Bovelder beef cows. On average, 36.2 oocytes per donor were retrieved. From these oocytes, 43 blastocysts were produ...

To examine the effect of melatonin on in vitro fertilization and embryonic development, mouse embryos after insemination in vitro were cultured in a physiological medium with or without melatonin. Melatonin increased the fertilization rate significantly at a concentration between 10(-6) and 10(-4) M (27.6 vs. 43.9 or 40.4%, P < 0.01). Furthermore, a significant increase in the rate of embryos r...

AIM The aim of the study was to examine the efficiency of psycho-education of candidates for the IVF in stress, anxiety and depression decreasing, and the impact of the psycho educative techniques on the successfulness of the treatment. METHOD A random sample of 64 candidates for IVF treatment is divided in two groups: control group without psycho-education (32 candidates) and intervention gr...

BACKGROUND Sono-automatic volume calculation (SonoAVC) automatically identifies and measures the dimensions of hypoechogenic areas within datasets acquired using three-dimensional ultrasound. The objective of this study was to evaluate the predictive value of automated antral follicle counts according to their relative sizes in women undergoing assisted reproduction treatment (ART). METHODS A...

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...

BACKGROUND Reversal of tubal ligation is requested by some women for various reasons. The present study aims to determine the rate of pregnancy after tubal ligation reversal. CASE In these case series, we reported fifteen women who requested tuboplasty after tubal ligation. In these cases reversal of tubal ligation was done in 15 women. Pregnancy occurred in 4 women (26.6%). Two term pregnanc...
