To determine whether arcuate kisspeptin neurons that drive GnRH secretion display functional deficits in peripubertal and prenatal androgen mouse models of polycystic ovary syndrome.
Monitored arcuate kisspeptin neuron synchronization events in vivo using GCaMP fiber photometry in peripubertal androgen (PPA) and prenatal androgen (PNA) mouse models.
Applied machine learning classification to assess cyclical activity patterns and quantified serum sex hormones, progesterone feedback suppression, and pituitary gonadotroph sensitivity.
Peripubertal androgen mice displayed a lower frequency of arcuate kisspeptin synchronization events, whereas prenatal androgen mice retained cyclical neuronal activity patterns despite lacking normal estrous cycles.
Algorithm-identified 'diestrous' prenatal androgen mice showed significantly increased synchronization event frequency compared to controls, paired with diminished progesterone feedback suppression and reduced gonadotroph sensitivity to GnRH.
