Effects of bovine ovarian storage conditions and vitrification on isolated preantral follicle viability

Abstract

The decreasing rate of successful pregnancies, both naturally and through assisted conception, has led to innovations in the way eggs, sperm, and embryos are stored. Despite these advances, the use of assisted reproductive techniques to preserve endangered or rare species remains unexplored. Since the location where samples are collected and facilities are often far apart, we aim to address part of this challenge by comparing different methods to store and handle ovarian tissue before freezing. This may pave the way for further research in preserving endangered species, despite the challenges posed by the distance between sample collection sites and suitable facilities.
