A comparison between quarter, partial and total laser assisted hatching in selected infertility patients.
BACKGROUND The object of this study was to evaluate the efficacy of laser assisted hatching (LAH) of embryos on implantation and pregnancy rates of a selected group of infertility patients. METHODS A total of 322 cycles using LAH was undertaken in our Centre between June 1998 and September 1999. Patients were offered LAH if they fell in either one or more of the following categories: (i) Pati...
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 کاملEffects of partial or complete laser-assisted hatching on the hatching of mouse blastocysts and their cell numbers
BACKGROUND It is still debatable whether a full-thickness assisted hatching (AH) is better than the partial zona thinning. In this research, we used a mouse model to study the effect of partial and complete laser-AH on the rate of completely hatched blastocyst and their cell numbers. METHODS In experiment 1, mouse morulae had 0, 1, 2 or 3 full-thickness openings of 10 microns created in the z...
متن کاملThe Outcomes of Intracytoplasmic Sperm Injection and Laser Assisted Hatching in Women Undergoing In Vitro Fertilization Are Affected by The Cause of Infertility
Background We sought to determine the association between factors that affected clinical pregnancy and live birth rates in patients who underwent in vitro fertilization (IVF) and received intracytoplasmic sperm injection (ICSI) and/or laser assisted hatching (LAH), or neither. MaterialsAndMethods In this retrospective cohort study, the records of women who underwent IVF with or without ICSI and...
