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...
سابقه و هدف: امروزه برای افزایش میزان باروری در آزمایشگاههای ivf از تکنیکهای مختلفی از جمله روش a.h برای کمک به خارج شدن جنین از زونا پلاسیدا استفاده میکنند. با توجه به گزارشات متناقض دربارهی تاثیر روش a.h بر میزان باروری در سالهای اخیر، این مطالعه به منظور تعیین ارتباط a.h مکانیکی روی میزان باروری بر روی بیماران نابارور تحت درمان به روش ivf در مرکز ناباروری اصفهان در سال 1378 انجام شد. مو...
The effect of continuous low-power He-Ne laser on the hatching rate and life span of Artemia urmiana
Artemia, as live food, is of vital importance in aquaculture. In this study, we have studied the helium-neon (He-Ne) laser beam with 10 mw on the hatching and life span of Artemia cysts. He-Ne laser irradiation was performed with a 10 mw power at 3, 4 and 5 h irradiation periods. Cysts were hatched by standard method. Hatching percentage after 4 h of irradiation was more than other treatments a...
Assisted Hatching (AH) is a technique performed after In Vitro Fertilization (IVF) and involves the artificial thinning or opening of the Zona Pellucida (ZP) prior to Embryo Transfer (ET) as an attempt to improve the probability of embryo implantation. AH can be performed by embryologists via mechanical, chemical, or laser-assisted means. A few studies suggest that a larger size of ZP opening/t...
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 ...
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...
