High-Fat Diet Alters LH Secretion and Pulse Frequency in Female Mice in an Estrous Cycle-Dependent Manner

Reproductive fitness in females is susceptible to obesogenic diets. Energy balance and reproduction are tightly regulated, in part, by hypothalamic neurons in the arcuate nucleus (ARC), and high-fat diet (HFD) can steadily increase estradiol levels in rodents. Estradiol regulates the reproductive axis via negative feedback mechanisms in ARC neurons by modulating pulsatile release of the gonadotropin luteinizing hormone (LH). However, it is...
