This experiment was designed to study the effects of different doses and different patterns of change in circulating concentrations of oestradiol on the genesis of the surge release of luteinising hormone (LH) and follicle stimulating hormone (FSH),

Stimulation by naloxone, an opioid antagonist, of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) secretion was examined in spring-born crossbred ram lambs raised under natural photoperiod. Vehicle (n = 6) or 1 mg naloxone/kg vehicle

Elevation of serum estradiol (E2) levels to ≈ 23 pg mL−1 on day 12 of the estrous cycle of the ewe eliminated LH pulses, but did not induce luteolysis and a preovulatory surge release of gonadotropins. The E2 treatment appeared to exert a functio

During the breeding season, five groups of three ewes were implanted at ovariectomy with 0.36, 0.5, 1.0 and 6.0 cm oestradiol implants or implants containing no steroid. Eleven days after receiving implants, blood samples were taken every 10 min for

Possible endogenous opioid peptide regulation of the preovulatory gonadotrophin surge was examined in ewes during the breeding season. Intact ewes (n = 54) were synchronized by treatment for 12 days with intravaginal sponges releasing medroxyprogeste
