Sturgeon oocytes, like those of other vertebrates, are arrested in
early meiosis and require a steroid or steroids to trigger meiosis
resumption or maturation. The identity of the maturation-inducing
steroid in sturgeons has present study was designed to investigate
in sterlet the follicular secretion and relative blood changes of free
and conjugated 17,20βP, 20βS and of the androgens T, 11KT, in
response to hormonal treatment and to determine the relative potencies of the progestagens, 17,20β-P, 20βS, P4 and S, in inducing oocyte final maturation in vitro
