Kisspeptin is a crucial neuropeptide that serves as the master regulator of reproductive hormone secretion and plays a fundamental role in hypothalamic-pituitary-gonadal axis function. This 54-amino acid peptide controls the release of GnRH (gonadotropin-releasing hormone), thereby regulating LH and FSH secretion and overall reproductive health. Research has explored its potential in addressing hormonal imbalance, reproductive wellness, and hormonal changes, making it an essential tool for investigating reproductive endocrinology and hormonal balance.
