Gastrointestinal leaks are severe complications after bariatric surgery, mainly related to postoperative anastomotic defects with substantial morbidity and mortality. Surgical interventions can be complicated with high ...
Androgens and the evolution of male-gender identity among male pseudohermaphrodites with 5α-reductase deficiency
(N Engl J Med, 1979)
To determine the contribution of androgens to the formation of male-gender identity, we studied male pseudohermaphrodites who had decreased dihydrotestosterone production due to 5α-reductase deficiency. These subjects were ...
