Enclomiphene vs hCG
Human chorionic gonadotropin (hCG) is an LH mimic: it binds the LH receptor on Leydig cells directly and stimulates testosterone production, bypassing the brain entirely. Because it acts at the testis, hCG can work even when the pituitary signal is deficient,

- Human chorionic gonadotropin (hCG) is an LH mimic: it binds the LH receptor on Leydig cells directly and stimulates testosterone production, bypassing the brain entirely. Because it acts at the testis, hCG can work even when the pituitary signal is deficient, which is why it is used to preserve or restore intratesticular function. The mechanistic contrast with enclomiphene is instructive — enclomiphene works one level higher, by releasing the hypothalamic-pituitary brake so the body makes its own LH, whereas hCG substitutes for LH from outside. Readers comparing the two can review the dedicated overview of hCG in testosterone and fertility research alongside the hCG reference protocol page, both of which frame hCG’s evidence base in the same research-only terms.
