Fertiga teams up with Fertilab Barcelona in AURORA-Donor study

Suppressing the pituitary gland is essential during ovarian stimulation. Traditionally done via daily GnRH-antagonist injections, this study compared that approach to an alternative: using oral progesterone (Medroxyprogesterone). The key takeaways from the AURORA-Donor study so far:

  1. Both protocols are equally effective in egg maturation, fertilization, blastocyst development, and genetic quality (euploidy).
  2. No significant difference in hormonal levels or stimulation duration, but the progesterone protocol is:
  • 💰 40x more cost-efficient
  • 💊 More patient-friendly (oral vs. daily injections)
  • 🧑‍⚕️ Easier for clinics to manage.

The next step? Exploring gene expression in cumulus cells to better predict outcomes like live birth – stay tuned for more from the AURORA-Donor study!
