Kisspeptin-10 (Kp-10) is the shortest bioactive fragment of the full-length kisspeptin peptide, derived from the KISS1 gene, and is widely recognized for its potent action on the hypothalamic-pituitary-gonadal (HPG) axis. It exerts its physiological effects primarily through binding to the GPR54 (KISS1R) receptor, where it plays a crucial role in the initiation of puberty, regulation of reproductive hormone secretion, and fertility maintenance.
Due to its short sequence and high receptor affinity, Kisspeptin-10 is favored in clinical research and diagnostic applications, especially for GnRH stimulation testing, ovulation induction, and investigation of puberty disorders.
Kisspeptin-10 acts via the following key pathways:
KISS1R Activation: Binds to GPR54 receptors on GnRH neurons, stimulating the pulsatile release of gonadotropin-releasing hormone (GnRH).
Upregulation of LH and FSH: Stimulated GnRH secretion leads to increased luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary gland.
Modulation of Sex Hormones: Through the LH/FSH axis, it regulates the production of testosterone, estradiol, and progesterone.
Pubertal Trigger: Essential for the physiological onset of puberty, acting as a switch for reproductive hormone activation.
Preclinical and Clinical Studies:
Fertility Induction: Kisspeptin-10 has been shown to safely induce egg maturation and ovulation in IVF patients without elevating the risk of OHSS (ovarian hyperstimulation syndrome).
Male Reproductive Support: Demonstrates the ability to raise testosterone and LH levels in hypogonadal men without disrupting natural feedback mechanisms.
GnRH Testing: Used in diagnostic endocrinology to assess hypothalamic function and differentiate between pituitary vs hypothalamic causes of hormone deficiency.
Puberty Disorders: Explored in delayed or disordered pubertal onset due to its tight control over GnRH pulse generation.
Research Models: Studied for its role in stress response, energy availability, and circadian regulation of reproductive function.
