Luteinizing Hormone Response to Pulsatile Luteinizing Hormone-Releasing Hormone in Prepubertal Heifers

Journal of Dairy Science, 1986
The effects of 12 hourly 5-micrograms injections of luteinizing hormone-releasing hormone on luteinizing hormone release, were examined in 18 prepubertal Holstein heifers at 4, 7, or 10 mo of age. During a 6-h pretreatment period, mean serum luteinizing hormone concentrations and mean number of endogenous luteinizing hormone episodes per hour were not ...

Successful outcome of a pregnancy derived from premature ovulation in a gonadotropin‐releasing hormone antagonist protocol: A case report

Clinical Case Reports, 2021
In the gonadotropin‐releasing hormone (GnRH) antagonist protocol, it is necessary to reinforce contraceptive guidance assuming that luteinizing hormone surge is not detected by measurement of serum level and ovulation is not suppressed by GnRH antagonist.

Investigating the KNDy hypothesis in humans by co-administration of kisspeptin, neurokinin B and naltrexone in men [PDF]

, 2016
Context: A subpopulation of hypothalamic neurons co-localise three neuropeptides namely kisspeptin, neurokinin B (NKB) and dynorphin collectively termed KNDy neurons. Animal studies suggest they interact to affect pulsatile GnRH release (KNDy hypothesis);

The Role of RFamide-Related Peptide-3 in Age-Related Reproductive Decline in Female Rats. [PDF]

, 2016
Reproductive senescence, the point in time when females cease to show estrous cyclicity, is associated with endocrine changes in the hypothalamus, pituitary, and gonads. However, the mechanisms triggering this transition are not well understood.
