Androgen insensitivity in squirrel monkeys

Androgen resistance in squirrel monkeys (Saimiri spp.).

The goal of this study was to understand the basis for high androgen levels in squirrel monkeys (Saimiri spp.). Mass spectrometry was used to analyze serum testosterone, androstenedione, and dihydrotestosterone of male squirrel monkeys during the nonbreeding (n = 7) and breeding (n = 10) seasons. All hormone levels were elevated compared with those of humans, even during the nonbreeding season;...

Complete Androgen Insensitivity Syndrome in Three Sisters

Sociophysiology of Squirrel Monkeys

Primate sociophysiology is an emerging discipline concerned with understanding the proximate mechanisms that contribute to the generation and maintenance of species-typical social systems. Studies of squirrel monkeys illustrate that sociophysiological processes are more varied than is commonly assumed with respect to both the effective social dimensions that influence physiological function and...

Androgen insensitivity syndrome

The androgen insensitivity syndromes (AIS) fall within the generic category of 46,XY DSD (disorder of sex development) and present as phenotypes associated with complete or partial resistance to the action of androgens. Three categories are recognized: complete androgen insensitivity syndrome (CAIS), partial androgen insensitivity syndrome (PAIS), mild androgen insensitivity syndrome (MAIS). Th...

Androgen Insensitivity Syndrome

Androgen Insensitivity Syndrome (AIS) is a human disorder in which an individual's genetic sex (genotype) differs from that individual's observable secondary sex characteristics (phenotypes). A fetus [4] with AIS is genetically male with a 46,XY genotype. The term 46,XY refers to the chromosomes found in most cells of the fetus [4]. Most cells have a total of 46 autosomes, or non-sex chromosome...
