A prospective randomized controlled study of the effect of short coincubation of gametes during insemination on zona pellucida thickness
|
Key words: ZONA PELLUCIDA, THICKNESS, SHORT EXPOSURE
ABSTRACT
A prospective, randomized study was conducted to evaluate the thickness of zona pellucida (ZP) after brief or standard exposure of human oocytes to spermatozoa, and to determine the correlation between ZP thickness, fertilization rate and embryo quality. The mean ZP thickness 48 h after insemination was found to be significantly less in fertilized oocytes than in non-fertilized oocytes in all treated groups (13.72 + o...

Unlocking Mystery of Fertilization; Sperm Gets Into Egg Like Virus Enters Cell
The Washington Post
