Follicular cumulus-enclosed goat oocytes were matured in vitro in the presence of granulosa cells, follicle stimulating hormone (FSH), luteinizing hormone (LH) and estradiol-17β. While 86% of the oocytes from follicles 2 to 6 mm in diameter achieved

The aim of our study was to define the conditions for IVM and IVF of oocytes in 2 common deer species as models for endangered related subspecies. Immature oocytes were recovered during the breeding season from postmortem ovaries (red deer) or by rep

Endocrine control of follicular growth was studied in mature Romanov ewes carrying (RF+) or not carrying (R+2) the Booroola Fec gene during an oestrous cycle after gonadotrophin-dependent follicles were suppressed by treatment with an antagonist of G
