Kisspeptin is a peptide that plays a central role in the body's reproductive hormone system, known as the HPG axis. Research shows it helps signal the release of LH and FSH from the pituitary, which in turn influence testosterone and estrogen — making it a key compound in hormone and reproductive research.

In research, it has been studied for its effects on reproductive hormone balance, ovulation and sperm function, libido, energy, cognition, and body composition.

Key Terms:

• HPG axis: The hormone signaling loop between the hypothalamus, pituitary, and gonads.
• LH (Luteinizing Hormone): Signals testosterone production in males and ovulation in females.
• FSH (Follicle-Stimulating Hormone): Supports sperm production in males and follicle growth in females.
