Prescription-only and indication-dependent. For fertility preservation / intratesticular-testosterone maintenance on TRT, small studies used ~125-500 IU subcutaneously every other day. For spermatogenesis induction in hypogonadotropic hypogonadism, typically ~1,000-2,500 IU two to three times weekly (often combined with FSH), titrated to response. For female ovulation/oocyte-maturation trigger, a single dose (~5,000-10,000 IU urinary or 250 µg recombinant). No dietary-supplement dose exists.
