CAPA-IVM Versus STANDARD IVM

Immature oocytes were plated into a 4-well dish (Nunc, Denmark) at 10 COCs/well using CAPA medium (Medicult IVM medium; Origio, Denmark supplemented with 1 mIU/mL rFSH, 5 ng/mL insulin, 10 nM estradiol, 10 mg/mL human serum albumin \[SAGE, Denmark\] and 25 nM CNP under oil for 24 h at 37°C, 6% carbon dioxide in air). After 24 hours, COCs were washed and transferred into IVM medium (Origio, Denmark) containing 5 ng/mL insulin, 10 nM estradiol, 100 ng/mL human recombinant amphiregulin and 100 mIU/mL rFSH, and incubated under oil for 30 h at 37°C, 6% carbon dioxide in air.

Immature oocytes are plated into a 4-well dish at 10 COCs/well using IVM medium supplemented with 75 mIU/mL recombinant FSH (Merck, Switzerland), 100 mIU/mL hCG (MSD, USA), 0.01 mg/mL growth hormone (Merck, Switzerland) and 10 mg/mL human serum albumin (SAGE, Denmark). COCs were incubated for 30 hours at 37°C, 6% carbon dioxide in air.
