Официальное название
An Observational Study to Evaluate the Expression Profiles of Oocyte-potency-related Genes in Cumulus Cells of Women Treated With Human Recombinant FSH (Hr-FSH)and Triggered With GnRH Agonist in an Oocyte Donation Program
Обзор
This is a randomized observational study. The main aim is to determine potential oocyte competence predictive mRNA expression profiles in the cumulus cells isolated form individual oocytes. In 2 patient cohorts: 1)GnRH Antagonist \& hr-FSH with GnRH Agonist trigger, 2) Progesterone \& hr-FSH with GnRH Agonist trigger.
Вмешательства
- Другое AURORA-Donor
Explorative study of cumulus cells gene expression in relation to the oocyte competence for good quality blastocyst formation and predictive for clinical pregnancy.
