Effects 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...

Effects of different hatcher temperatures on hatching traits of broiler embryos during the last five days of incubation
This study deals with the effects of different hatcher temperatures on hatching traits in modern commercial broiler eggs during the last five days of incubation. The hatching eggs were obtained from a 52wk old (Ross 308) flock. All eggs were distributed randomly into one incubator and incubated for 17 d using uniform conditions (37.6 ± 0.5 °C and 58% relative humidity). At the start of 18 days ...
متن کاملLaser-assisted hatching of embryos in women of advanced age after in vitro fertilization: a preliminary report.
BACKGROUND For infertile women aged over 37 years, failure of the zona pellucida to rupture is believed to be associated with a decreased implantation rate in in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). It has been suggested that assisted hatching of embryos will increase the pregnancy rate with IVF by means of mechanically facilitating the hatching process. METHO...
متن کاملThe effects of laser assisted hatching on pregnancy rates
BACKGROUND For infertile women aged over 35 years, failure of the ZP (zona pellucida) to rupture is believed to be associated with a decreased implantation rate in in vitro fertilization (IVF) or intra cytoplasmic sperm injection (ICSI). OBJECTIVE In this research, laser assisted hatching (LAH) was offered to patients with advanced maternal age to evaluate a possible benefit. MATERIALS AND ...
