Abstract


The present study aimed to investigate the role of inhibin in the regulation of oocytes
maturation. Inhibin was isolated from goat granulose cells and injected by intraperitoneal in to female
Nile-Tilapia. Three days later its gonad was taken by decapitation and the change of oocyte was evaluated
under microscope. Results showed that average of percentages of oocytes that undergo maturated after
exposed with inhibin of 0, 20, 40, and 60
µg/individual 50.05, 29.44, 21.46, and 30.83%, respectively.
The exposure of doses of goat inhibin in Nile-Tilapia showed significantly different (P<0.01) to
percentages of mature oocytes. It was conluded that exposition of goat inhibin from granulose cells can
inducing the maturation of Nile-Tilapia oocytes.
