The present invention relates to the field of culture of ovary tissue comprising an oocyte and in particular to a method of stabilisation of the ovary tissue comprising contacting the ovary tissue with a medium comprising fetuin-B immediately after its isolation from a female body. By this contacting, fetuin-B maintains the fertilisable state of the oocyte by preventing the premature hardening of the zona pellucida of the oocyte by inhibiting the activity of ovastacin to cleave ZP2 to ZP2f. The present invention further relates to the culture of ovary tissue comprising an oocyte whereby the ovary tissue has been isolated from a female individual, wherein the serum fetuin-B level is enhanced in the female individual.
