| 词条 | Assisted zona hatching |
| 释义 |
Assisted zona hatching (AZH) is a procedure of assisted reproductive technology in which a small hole is made in the zona pellucida, using a micromanipulator, thereby facilitating for zona hatching to occur.[1][1] Zona hatching is where the blastocyst gets rid of the surrounding zona pellucida to be able to implant in the uterus. EfficacyA systematic review and meta-analysis came to the result that assisted zona hatching is related to increased rates of clinical pregnancy and multiple pregnancy in women with previous repeated failure or frozen-thawed embryos.[2] However, it is unlikely to increase clinical pregnancy rates when performed in fresh embryos transferred to unselected women, to those without poor prognosis or to women of advanced maternal age.[2] Also, overall, there no evidence of a significant difference in live birth rate following assisted hatching compared with no assisted hatching.[3] References1. ^1 IVF-infertility.com {{Assisted reproductive technology}}{{DEFAULTSORT:Assisted Zona Hatching}}{{Human-repro-stub}}2. ^1 {{Cite journal | last1 = Martins | first1 = W.
