J Endocrine Society 7(S1):bvad114.1215. doi: 10.1210/jendso/bvad114.1215
Objective: To examine the impact of partial loss of KNDy neurons in prenatally androgen-treated female rats on luteinizing hormone (LH) secretion and ovarian morphology, as a model of polycystic ovary syndrome (PCOS).
Summary: The study found that the ablation of KNDy neurons resulted in increased LH pulse amplitude and mean LH levels without affecting pulse frequency, and partially restored the number of primordial follicles, suggesting KNDy neurons’ role in modulating LH release and ovarian reserve in PCOS.
Usage: Intra-ARC stereotaxic injections of the neurokinin-3 receptor agonist conjugated with Saporin (NKB-SAP, IT-63) to induce the lesion of KNDy neurons. Blank-SAP (IT-21) was used as a control.
