Comparative StudyPregnancy rates in donor oocyte cycles compared to similar autologous in vitro fertilization cycles: an analysis of 26,457 fresh cycles from the Society for Assisted Reproductive Technology.
To use a large US IVF database and compare pregnancy outcomes in fresh donor oocyte versus autologous IVF cycles in women age 20-30 years. ⋯ Recent US data suggest that the hormonal environment resulting from autologous ovarian stimulation lowers IVF success rates. Further research is needed to determine when to avoid fresh embryo transfer in autologous patients.

Dual trigger with gonadotropin-releasing hormone agonist and standard dose human chorionic gonadotropin to improve oocyte maturity rates.
To evaluate the percentage (%) of mature oocytes retrieved in patients with a previous history of >25% immature oocytes retrieved who were triggered with gonadotropin-releasing hormone agonist (GnRH-a) and human chorionic gonadotropin (hCG) to induce oocyte maturation. ⋯ In patients with a low percentage of mature oocytes retrieved who are triggered with a combination of GnRH-a and hCG, the % of mature oocytes retrieved improved. in vitro fertilization outcomes, however, remain poor, suggesting an underlying oocyte dysfunction.
