Cryptorchidism in the orl rat is associated with muscle patterning defects in the fetal gubernaculum and altered hormonal signaling

This study was designed to provide additional insight into testicular hormone production and responsiveness in the orl strain and complement ongoing efforts to characterize the genetic basis of cryptorchidism in this isolated rat colony.本研究旨在深入解析orl品系（orl strain）大鼠的睾丸激素产生与激素应答特性，并为当前针对该隔离大鼠种群中隐睾症（cryptorchidism）遗传基础的表征研究提供补充支撑。
