Raw research findings for this medication. Mostly single studies, not curated or confirmed robust.
Human chorionic gonadotropin (hCG) is a pregnancy hormone that acts on the same receptor as luteinising hormone. Injected, it is used in fertility treatment to trigger the final maturation and release of eggs, to treat some cases of undescended testes in boys and low hormone levels in men. It is sold as Pregnyl, Novarel and Ovidrel, among other names.
As a protein hormone, hCG is not handled by drug-processing enzymes. The gene study listed looked at FSHR, the FSH receptor gene, for the amount of hormone needed in fertility treatment. The evidence is weak, and there is no CPIC or DPWG guideline.
