Background: The KISS1 gene, is a critical regulator of normal reproductive function. In humans, KISS1 deletion results in a failure to go through puberty while activating mutations result in central precocious puberty. Administration of kisspeptin induces ovulation in rodents and sheep. However chronic exposure to exogenous kisspeptin-54 leads to profound tachyphylaxis in women with hypothalamic amenorrhoea. It is not known whether exogenous kisspeptin can alter the m...

Background: Hypothalamic amenorrhoea (HA) accounts for over 30% of cases of amenorrhoea in women of reproductive age. Current treatments have limited success rates and side effects. We have recently shown that a single injection of the novel hormone kisspeptin potently stimulates reproductive hormone release in women with HA. However, twice-daily kisspeptin administration to women with HA, results in tachyphylaxis due to desensitisation of the kisspeptin receptor. This suggest...
