Purpose : To validate an expedited method for the removal of erythrocytes when preparing IVF granulosa-luteal cells for culture.
Methods : Granulosa cells were enriched for culturing from follicular aspirates by density gradient centrifugation and by hypo-osmotic lysis treatments.
Results : Cells prepared by either method showed the same cell viability and produced progesterone in similar quantities.
Conclusions : Using hypo-osmotic lysis to remove erythrocytes does not impair granulosa cell viability or steroidogenesis. It avoids multiple density gradient centrifugations and washings, and yields IVF granulosa cells ready for culture efficiently.
