Association between Thrombophilia and Repeated Assisted Reproductive Technology Failures.
PURPOSE This study was performed to investigate the incidence of thrombophilic gene mutations in repeated assisted reproductive technology (ART) failures. METHODS The prevalence of mutated genes in the patients with a history of three or more previous ART failures was compared with the patients with a history of successful pregnancy following ARTs. The study group included 70 patients, 34 wit...
متن کاملImplantation failures: success of assisted hatching with quarter-laser zona thinning.
Implantation failure after IVF is one of the factors associated with a reduced chance of pregnancy for some patients. Assisted hatching methodologies are designed to facilitate the embryo's escape from the zona pellucida, and this strategy has been suggested as a means of improving pregnancy rates in patients with previous implantation failure. The aim of this prospective and randomized study w...
متن کاملOutcomes of vitrified-warmed cleavage-stage embryo hatching after in vitro laser-assisted zona pellucida thinning in patients.
The aim of the present study was to determine whether the size of the zona pellucida (ZP) thinning area by laser-assisted hatching affected the potential development of vitrified-warmed embryos. A total of 196 vitrified-warmed cleavage-stage embryos (from 49 patients, four sister embryos per patient) were used in the study, i.e., four sister embryos from each patient were randomly assigned to f...
متن کاملLaser-assisted zona pellucida thinning prior to routine ICSI.
BACKGROUND In MII oocytes showing difficult oolemma breakage, ICSI can cause an increase in the degeneration rate. This may be overcome by laser-assisted ICSI using a 5-10 micro m opening in the zona pellucida for injection. However, such a small opening might impair the hatching process, especially if assisted hatching is applied in addition. In order to prevent this, the present study used ro...
متن کاملOver-challenging Mothers: Motherhood after Assisted Reproductive Technology
Background & aim: The experience of having a child is a new experience that can be challenging for mothers. However, this experience can be different for mothers who are subjected to assisted reproduction techniques, compared to mothers with normal fertility experience. The assisted reproductive techniques influence the attitudes and expectations of mothers towards the...
