HPG axis modulation

The hypothalamic-pituitary-gonadal axis regulates reproductive hormone secretion and function.

Biological pathway

Kisspeptin activates KISS1R on GnRH neurons, increasing GnRH and downstream LH/FSH signalling.

Evidence summary

Kisspeptin has strong mechanistic and reproductive endocrinology evidence, with early human research in sexual desire.

Limitations

Hormonal signalling effects do not establish broad treatment effectiveness for libido or fertility.
