Natural cycle oocyte donation
Stimulated cycle oocyte donation. Long protocol down-regulation with a GnRH agonist, starting on the midluteal phase of the previous cycle with leuprolide acetate (0.2mg/day). Once evidence of downregulation is documented, leuprolide will be halved to 0.1 mg daily. COH with be carried on with gonadotropins (150UI/day of rFSH and 75 UI/day of HP-hMG). The dose can be adjusted according to ovarian response as judged by ultrasound and by serum oestradiol (E 2 ) concentrations.
