在鹌鹑视前区（POA），神经降压素免疫反应（NT-ir）细胞主要位于视前内侧核（POM）。它们在女性中的数量多于男性，并且在女性中，它们的数量在排卵周期中变化。这表明类固醇激素对POA中NT表达的控制。通过比较接受或未接受睾酮治疗的性腺切除男性和女性的NT-ir群体来验证这一想法。无性别差异的NT-免疫反应细胞的数量存在于性腺切除鸟类。替吉奥处理增加了免疫反应性胞体的数量。这种效应在解剖学上是特异性的，在前连合尾侧区域观察到增加，但在POM本身没有观察到增加。
IN the quail preoptic area (POA), neurotensin-immunoreactive (NT-ir) cells are mostly located in the sexually dimorphic medial preoptic nucleus (POM). They are more numerous in females than in males and, in females, their number varies during the ovulatory cycle. This suggests a control by steroids of NT expression in the POA. This idea was tested by comparing the NT-ir populations in gonadectomized males and females treated or not with testosterone. No sex differences in the NT-ir cell number was present in gonadectomized birds. Testosterone treatment increased the number of immunoreactive perikarya. This effect was anatomically specific and the increase was observed in the area caudal to the anterior commissure but not in POM itself.
