    Pituitary hCG

    The anterior stalk of the pituitary secretes luteinizing hormone (LH), which shares an alpha subunit with hCG. In normal menstrual cycles, pituitary generated hCG may be detectable at the time of the LH surge. Estrogen provides negative feedback for this LH secretion and acts as a suppressing agent. In patients in low-estrogen states (perimenopause, menopause, and status postoophorectomy), pituitary hCG may be secreted in increasing amounts, although only levels between 1 to 32 mIU/mL have been recorded.[1] To confirm a pituitary source for the hCG, patients are started on high-dose oral contraceptive pills to produce an exogenous source of estrogen. In general, patients with pituitary hCG will have their hCG levels suppressed after 3 weeks on this regimen.[1]
