A Study of Clinical Parameters Influencing Human Zona Pellucida Thickness / 대한산부인과학회잡지

ABSTRACT

The purpose of present study was to assess which parameters influence human oocyte zona pellucida(ZP). Zone pellucida thickness was evaluated in 124 oocytes of 16 cycles IVF-ET with intracytoplasmic sperm injection(ICSI) between July 1995 and October 1995 at the department of obstetrics and Gynecology, Yonsei university, Wonju Christian Hospital. The zone pullucida thickness was 17.7+/-2.0micronm(mean+/-SD) for 107 metaphase II oocy- tes. The zona pullucida thickness was singinficantly different according to maximum estr- adiol(E2) value ; The mean thickness of Zona pellucida was thinner below 2000 pg/ml of E2 value than that above 2001 pg/ml of E2 value(p0.05).
