Androgens and the evolution of male-gender identity among male pseudohermaphrodites with 5α-reductase deficiency
Imperato-McGinley, Julianne; Peterson, Ralph E.; Gautier, Teofilo; Sturla, Erasmo (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 ... -
Decreased Urinary C19 and C21 Steroid 5α-Metabolites in Parents of Male Pseudohermaphrodites with 5α- Reductase Deficiency: Detection of Carriers
Imperato-Mcginley, Julianne; Peterson, Ralph E.; Gautier, Teófilo; Arthur, Ann; Shackleton, Cedric (The Journal of Clinical Endocrinology & Metabolism, 1985-05-01)The urinary 5β/5α ring A-reduced metabolites of C19 and C12 steroids from obligate carrier parents of male) pseudohermaphrodites with 5a-reductase deficiency were analyzed by gas chromatography. Etiocholanolone/androsterone, ... -
Hormonal evaluation of a large kindred with complete androgen insensitivity: evidence for secondary 5α-reductase deficiency.
Imperato-McGinley, Julianne; Peterson, Ralph E.; Gautier, Teófilo; Cooper, George; Danner, Robert; Arthur, Ann; Morris, Patricia l.; Sweeney, William j.; Shackleton, Cedric (The Journal of Clinical Endocrinology & Metabolism, 1982-05)Seventeen individuals from a pedigree with complete androgen insensitivity, [testicular feminization (TF)] are presented. Their hormonal evaluation was compared with those of normal males and male pseudohermaphrodites with ... -
Male pseudohermaphroditism due to multiple defects in steroid-biosynthetic microsomal mixed-function oxidases — a new variant of congenital adrenal hyperplasia
Peterson, Ralph E.; Imperato-McGinley, Julianne; Gautier, Teófilo; Shackleton, Cedric (New England Journal of Medicine, 1985-11-07)A six-month-old 46,XY infant with a female phenotype and ambiguous genitalia was evaluated for male pseudohermaphroditism. The principal findings were (1) low basal plasma levels of all measured C19 steroids and their ... -
Male pseudohermaphroditism secondary to 5α-reductase deficiency—A model for the role of androgens in both the development of the male phenotype and the evolution of a male gender identity
Imperato-Mcginley, Julianne; Peterson, Ralph E.; Gautier, Teófilo (Journal of Steroid Biochemistry, 1979)Male pseudohermaphroditism secondary to 5α-reductase deficiency is reviewed. At birth, the affected males (46 XY) have a clitoral-like phallus, bifid scrotum and urogenital sinus with the testes in the inguinal canals or ... -
Testicular function in 2 cases of penile agenesis
Gautier, Teófilo; Salient, Jorge; Pena, Santiago; Imperto-McGinley, Julianne; Peterson, Ralph E. (The Journal of Urology, 1981-10-05)Two cases of congenital absence of the penis are presented. In both cases testicular androgen function was adequate, as judged by measurements of plasma androgens after administration of human chorionic gonadotropin
