CONTEXT AND OBJECTIVE GH therapy increases growth and adult height in Turner syndrome (TS). The benefit to risk ratio of adding the weak androgen oxandrolone (Ox) to GH is unclear. DESIGN AND PARTICIPANTS A randomized, placebo-controlled, double-blind, dose-response study was performed in 10 centers in The Netherlands. One hundred thirty-three patients with TS were included in age group 1 (2-...
The book is well written and entertaining, providing both new interpretations of developmental stages for psychoanalysts and a good basic review of the fundamental psychoanalytic principles for those of us who are less familiar with these principles. The main body of the book describes in great detail rituals in several different Papua New Guinea tribes. These rituals are basically the same, wi...
Available information on organochlorines and the chronic effects of exposure to them are set out. Organochlorinated compounds are the most persistent pesticides and can be found in all ecosystems. Although they are generally efficient in pest control, they are also a potent environment pollutant and can provoke health problems in man. The evidences of the carcinogenic potential of organochlorin...
Female moles of the Old World genus Talpa display a curious suite of reproductive features that include a peniform clitoris and ovaries with a discrete interstitial gland or testis-like region (so-called 'ovotestes'). The masculinization of the female external genitalia in Talpa has accordingly been linked with secretion of androgens from the interstitial gland region of the fetal gonad. Althou...
The deficiency of C-21-hydroxylation in adrenocorticosteroid synthesis is the commonest cause of congenital virilizing adrenal hyperplasia (CVAH). Abnormal secretory activity in CVAH begins about the third month of gestation before the differentiation of external genitalia (Bierich, 1963). The masculinization of the female external genitalia noted at birth in almost all cases is thought to resu...
Though the familial occurrence of virilization associated with hyperplasia of the adrenal cortex has long been established, there have been only two reports of the familial aggregation of virilizing adrenal carcinoma. It is the purpose of the present communication to describe a family in which 2 sibs, who were products of a consanguineous marriage, had virilizing tumours ofthe adrenal cortex pr...
Many transgender men and women seek hormone therapy as part of the transition process. Exogenous testosterone is used in transgender men to induce virilization and suppress feminizing characteristics. In transgender women, exogenous estrogen is used to help feminize patients, and anti-androgens are used as adjuncts to help suppress masculinizing features. Guidelines exist to help providers choo...
Female social dominance (FSD) over males is unusual in mammals, yet characterizes most Malagasy lemurs, which represent almost 30% of all primates. Despite its prevalence in this suborder, both the evolutionary trajectory and proximate mechanism of FSD remain unclear. Potentially associated with FSD is a suite of behavioural, physiological and morphological traits in females that implicates (as...
Leydig cells are the steroidogenic lineage of the mammalian testis that produces testosterone, a key hormone required throughout male fetal and adult life for virilization and spermatogenesis. Both fetal and adult Leydig cells arise from a progenitor population in the testis interstitium but are thought to be lineage-independent of one another. Genetic evidence indicates that Notch signaling is...
A descriptive epidemiological study of simple hypospadias-that is, hypospadias without coexisting malformation outside the genital system-in a birth population of 46,927 singleton males and 1,013 twin males showed that the condition was significantly more common (P < 0.001) in uniovular twin males than in either singleton or binovular twin males. Also the temporal distribution of dates of conce...
