Werkingsmechanisme

Gonadorelin

Gonadorelin acts as an agonist at the GnRH receptor on the gonadotroph cells of the pituitary and triggers release of the gonadotropins luteinizing hormone (LH) and follicle-stimulating hormone (FSH). The temporal pattern of receptor exposure is decisive: pulsatile administration mimics the natural hypothalamic secretory rhythm and sustains LH/FSH release, whereas continuous exposure leads to receptor internalisation and desensitisation with subsequent paradoxical suppression of gonadotropins. The latter principle is exploited therapeutically by longer-acting GnRH agonists.

Sekretin

Secretin binds the Gs-coupled secretin receptor (SCTR) on pancreatic duct cells, opens CFTR chloride channels and triggers secretion of bicarbonate-rich pancreatic fluid and bile flow.

Frequently asked questions

What is the difference between Gonadorelin and Sekretin?: Gonadorelin is classified as "Onderzoek (overig)", while Sekretin is classified as "Onderzoek (overig)". Gonadorelin: Gonadorelin is the synthetic decapeptide with an amino-acid sequence identical to endogenous gonadotropin-releasing hormone (GnRH/LHRH). Historically approved in several countries for diagnostic testing of pituitary function and for fertility indications (pump systems). A defining feature is the opposite effect of pulsatile versus continuous administration: pulsatile stimulates, continuous leads to receptor desensitisation. Sekretin: Secretin is a 27-amino-acid hormone that regulates pancreatic bicarbonate secretion. As ChiRhoStim it is FDA-approved as a diagnostic agent (pancreatic function test, gastrinoma test, secretin-enhanced MRCP). This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
Which peptide is better supported by science, Gonadorelin or Sekretin?: The highest available evidence level is "Humane studie" for Gonadorelin and "Humane studie" for Sekretin. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
What is the legal status of Gonadorelin and Sekretin in Germany and the United States?: Duitsland: Gonadorelin — Op recept, Sekretin — Op recept. Verenigde Staten: Gonadorelin — Op recept, Sekretin — Op recept. These are factual summaries with source and review date on the individual pages.
