目的性腺发育不全中的性别分化通常是不对称的。在真正的两性畸形患者中,一侧可能有卵巢和苗勒氏管,另一侧可能有睾丸和沃尔夫氏管。这种不对称表明睾丸激素仅在性分化的早期阶段局部起作用。我们测试了睾酮通过沿着管道输送而不是通过简单扩散到达沃尔夫管的假设。材料和方法将小鼠 14 天的泌尿生殖嵴置于器官培养物中,并显微注射睾酮-白蛋白-异硫氰酸荧光素。结果在 17 小时在整个沃尔夫管中发现荧光,到 48 小时在扩张的尾端荧光达到最大。结论我们的结果支持假设雄激素可能沿着沃尔夫管运输。睾丸激素分泌到沃尔夫管中可以将激素水平维持在生物活性范围内。
PurposeSexual differentiation in gonadal dysgenesis is commonly asymmetrical. In patients with true hermaphroditism there may be an ovary and mullerian duct on 1 side, and a testis and wolffian duct on the other side. Such asymmetry suggests that testicular hormones only act locally at this early stage of sexual differentiation. We tested the hypothesis that testosterone reaches the wolffian duct by transport down the duct rather than by simple diffusion.Materials and MethodsMouse 14-day urogenital ridges were placed in organ culture and microinjected with testosterone-albumin-fluorescein isothiocyanate.ResultsAt 17 hours fluorescence was found throughout the wolffian duct and by 48 hours it was maximal in the dilated caudal end.ConclusionsOur results support the hypothesis that androgens may be transported along the wolffian duct. Secretion of testicular hormones into the wolffian duct may maintain hormone levels in the biologically active range.
