Article Synopsis
- Previous studies mainly focused on Zona Pellucida (ZP) thickness and embryo characteristics but did not explore the impact of ZP thinning, ooplasm volume shrinkage, and perivitelline space (PVS) increase on embryo implantation and pregnancy.
- A retrospective study involving 281 patients analyzed these parameters in embryos with varying outcomes and found significant differences between those that implanted successfully and those that did not.
- The results indicated that implanted embryos exhibited a greater percentage of ZP thinning, a larger reduction in ooplasm volume, and an increase in PVS volume compared to non-implanted embryos, suggesting these factors could aid in embryo selection.
A parallel group superiority prospective randomised controlled trial was devised to compare the culture characteristics of human pre-implantation stage embryos during uninterrupted culture in a time lapse incubator (TLI) versus the conventional model of interrupted culture in a standard incubator (SI) under low oxygen tension using a single step medium. 221 patients aged 35-and-under, 124 patients aged between 36 and 39 and 86 patients aged 40-and-over years were randomised and cultured either in a SI or in a TLI. Patients in the three age groups were distributed between the TLI and SI in a 1:1 ratio.

The study included 1954 Palestinian women records which were reviewed and analyzed statistically from 2000-2005. Those women attended In vitro fertilization center in Gaza complaining from infertility and abortion.
