An improved mechanical technique for assisted hatching.

BACKGROUND Varied clinical outcomes of assisted hatching (AH) have been reported. We attempt to investigate whether the size of the zona opening created by AH is adequate for blastocyst hatching, and, if not, set up a new method to improve it. METHODS A new AH technique, long zona dissection (LZD), was established, and experiments were performed to compare the effects of different sizes of zo...

Assisted Hatching for In Vitro Fertilization-Embryo Transfer: An Update

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...

Relevance of Assisted Hatching with Blastocyst Stage Transfer

When a blastocyst expands with the growth of the blastocoel, it stretches and thins the zona pellucida (ZP), ultimately rupturing the ZP allowing the embryo to hatch free ready for implantation. In the event this does not occur, then an otherwise potentially viable embryo may not implant. Assisted hatching (AH) has been developed to overcome this, but has been applied mostly to day-2/3 embryos ...

The 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 ...
