“…The artificial gap or slit should allow the most molecules from the endometrium to cross the ZP, as well as increase the communication and earlier contact between embryo and endometrium. This procedure may result in increased PRs in IVF (16).…”

“…To date, most researchers suggest that selective AH may have benefits to embryo implantation (Cohen et al 1992). However, it is still controversial whether the cryopreservation procedure will change the structure of zona pellucida and AH is necessary to improve the implantation ability of frozen-thawed embryos (Veiga et al 2004). Some researchers suggested that cryopreservation will induce zona change, so AH can increase the implantation of frozen-thawed embryos (Check et al 1996, Tao & Tamis 1997, Gabrielsen et al 2004, Balaban et al 2006, Ge et al 2008, while other researchers have opposing views (Edirisinghe et al 1999, Primi et al 2004, Ng et al 2005, 2008, Sifer et al 2006.…”

The cryopreservation of human embryos is thought to induce alteration in the glycoprotein matrix and lead to zona change. However, this assumption has been full of controversies till now. The objective of this study was to evaluate the effect of cryopreservation on zona pellucida of human embryos. Fresh (nZ106, from 40 patients) and frozen-thawed embryos (nZ123, from 40 patients) were obtained from consenting patients who received conventional IVF and ICSI treatment. The birefringence of zona pellucida in human fresh and frozen-thawed embryos was imaged and quantitatively analyzed using polarized light microscopy before embryo transfer. There was no significant difference in retardance and thickness of the zona pellucida multilaminar structure between the two groups. Pregnancy and implantation rates of transferred fresh and frozen-thawed embryos were also compared. No significant difference was found in the rates of clinical pregnancy (47.5 vs 37.5%) and implantation (24.5 vs 23.2%) between the two groups. This study suggests that there is no significant change in the zona pellucida birefringence of human embryos before and after cryopreservation.
