Circulating reproductive hormones and hypothalamic oestradiol and progestin receptors in infertile Zucker rats

Abstract
Plasma concentrations of LH, FSH, prolactin and progesterone were measured during the oestrous cycle in obese (fa/fa) and non obese (Fa/?) Zucker rats. In obese rats the mid-afternoon surge of LH during prooestrus was reduced compared with that in non-obese rats (PPJournal of Endocrinology (1989) 120, 331–336
