Clomiphene for hypogonadism complicated by polycythemia.

Male hypogonadism is associated with poor sexual function. Testosterone therapy via the intramuscular route is the preferred treatment but is associated with secondary polycythemia. We report a patient in whom clomiphene citrate improved hypogonadal symptoms and restored normal free testosterone levels.

Intranasal Insulin Administration Does Not Affect LH Concentrations in Men with Diabetes.

A quarter of men with obesity or type 2 diabetes have hypogonadotropic hypogonadism. Animal studies and in vitro data have shown that insulin action and insulin responsiveness in the brain are necessary for the maintenance of the functional integrity of the hypothalamo-hypophyseal-gonadal axis. We conducted a randomized, placebo-controlled trial to evaluate the effect of one dose of intranasal insulin (40 IU of regular insulin) or saline on LH concentrations in 14 men (8 with type 2 diabetes and 6 healthy lean men).

Testosterone replacement and cardiovascular safety: no straight and narrow!

The past decade has seen a tremendous increase in the number of men treated for hypogonadism with the expectation of symptomatic benefit. However, the long-term cardiovascular safety of testosterone replacement remains unknown because retrospective studies of testosterone replacement have been inconsistent, and definitive, prospective, randomized studies are lacking. The purpose of this review is to critically appraise the studies on testosterone replacement and cardiovascular outcomes.

Minoxidil-associated exudative pleural effusion.

Recurrent pleural effusions are associated with significant morbidity and mortality. Drug-related reactions causing pleural effusions are not common, but their identification can potentially improve patient outcome. Minoxidil has been implicated in pleuropericardial effusions in patients with chronic kidney disease.
