Fertility and hormone-axis peptides - HCG, HMG, gonadorelin, kisspeptin and GnRH agonists.
Glycoprotein hormone
A hormone that mimics luteinizing hormone to stimulate the gonads to produce sex hormones and support ovulation or sperm/testosterone production.
Gonadotropin mixture
A purified hormone preparation containing both follicle-stimulating hormone and luteinizing hormone activity used to stimulate the ovaries or testes.
Synthetic GnRH
A synthetic copy of the natural hypothalamic hormone that signals the pituitary to release LH and FSH.
Peptide fragment
A short peptide that acts upstream of GnRH to switch on the reproductive hormone axis.
GnRH agonist decapeptide
A long-acting synthetic GnRH agonist that ultimately suppresses sex hormone production.
Nonapeptide hormone
The 'bonding' hormone that also drives uterine contractions and milk letdown.
