Application

17α,20β-Dihydroxy-4-pregnen-3-one has been used as a fish pheromone candidate to study its effect on ciliated and microvillous olfactory receptor neurons. It has also been used as a chemical stimulant to study the behavioral and hormonal responses in focal male cichlid fish.

Biochem/physiol Actions

17α,20β-Dihydroxy-4-pregnen-3-one, also known as maturation-inducing hormone (MIH) or DHP, is the most potent steroid for inducing final oocyte maturation in several species of fish. DHP as a progestin regulates spermiation, improves sperm motility and acts as a pheromone in male cyprinids.
