Differential Osmotic Behavior of Mammalian Oocytes before and after Maturation: A Quantitative Analysis Using Goat Oocytes as a Model

This study shows that immature and mature goat oocytes respond differently to hyperosmotic stress; when exposed to a 1.5 M propanediol solution, immature oocytes manifest a higher osmotic stress than do mature oocytes. This is the consequence of both higher water permeability (133.9 ± 15.2 vs 82.4 ±...
