A 31-year-old man presenting with an 18-month history of sexual dysfunction resulting from severe adult-onset IHH (LH U/L, FSH U/L, T nmol/L). Initial therapy with 50 mg of clomiphene citrate (CC) three times a day for 7 days, with overnight LH pulse profiling and 9 am T levels evaluated at baseline and on completion. A 2-month washout period, followed by low-dose maintenance therapy (25-50 mg/d) for 4 months.
MAIN OUTCOME MEASURE(S):Baseline and stimulated T levels and LH pulsatility; effect on sexual function.
RESULT(S):Clomiphene therapy resulted in complete normalization of pulsatile gonadotropin secretion, serum T level, and sexual function. CONCLUSION(S):Isolated hypogonadotropic hypogonadism may result from an acquired defect of enhanced hypothalamic sensitivity to E-mediated negative feedback. Whereas direct T replacement therapy can further suppress endogenous gonadotropin secretion, treating IHH men with gonadotropins can stimulate endogenous T secretion and enhance fertility potential. On theoretical grounds, reversal of gonadotropin deficiency with CC might be expected to have a similar biological effect.
In rare cases, birth control pills, also known as oral contraceptives , can cause benign tumors called hepatic adenomas . But it is not known if they increase the risk of hepatocellular cancer. Some of the studies that have looked at this issue have suggested there may be a link, but most of the studies were not of high quality and looked at types of pills that are no longer used. Current birth control pills use different types of estrogens, different estrogen doses, and different combinations of estrogens with other hormones. It is not known if the newer pills increase liver cancer risk.
