Kisspeptin vs Gonadorelin
| Attribute | Kisspeptin Kisspeptin-10 | Gonadorelin GnRH |
|---|---|---|
| Category | Sexual Function & Hormones | Sexual Function & Hormones |
| Best known for | HPG axis activation research | GnRH-axis research |
| In plain English | Kisspeptin is the 'on switch' for the reproductive hormone cascade. It tells the brain to release the hormone that signals testosterone and estrogen production. | Where hCG fakes the LH signal, gonadorelin pings the pituitary upstream to release real LH and FSH — keeping the entire HPG axis active. |
| How it works | Stimulates GnRH neurons in the hypothalamus, which then triggers LH and FSH release from the pituitary, leading to gonadal sex hormone production. | Stimulates pituitary release of LH and FSH via the GnRH receptor. |
| Researchers study | Reproductive hormone disorders, puberty timing, fertility, and emotional/sexual brain processing. | Hypogonadism, fertility, and HPG axis assessment. |
| Internet discussion | Discussed as a more 'natural' alternative to hCG for HPG axis support. | Discussed as a more 'physiological' alternative to hCG. |
Kisspeptin
HPG axis activation research
Kisspeptin is the 'on switch' for the reproductive hormone cascade. It tells the brain to release the hormone that signals testosterone and estrogen production.
Stimulates GnRH neurons in the hypothalamus, which then triggers LH and FSH release from the pituitary, leading to gonadal sex hormone production.
Reproductive hormone disorders, puberty timing, fertility, and emotional/sexual brain processing.
Discussed as a more 'natural' alternative to hCG for HPG axis support.
Kisspeptin is a hypothalamic 'master switch' for the reproductive hormone cascade.
Gonadorelin
GnRH-axis research
Where hCG fakes the LH signal, gonadorelin pings the pituitary upstream to release real LH and FSH — keeping the entire HPG axis active.
Stimulates pituitary release of LH and FSH via the GnRH receptor.
Hypogonadism, fertility, and HPG axis assessment.
Discussed as a more 'physiological' alternative to hCG.
Gonadorelin is synthetic GnRH researched as an upstream HPG axis stimulator.
