Sex determination [PDF]

open access: yesCurrent Biology, 2012
SummaryMulticellular animals are a diverse lot, with widely varied body plans and lifestyles. One feature they share, however, is a nearly universal reliance on sexual reproduction for species propagation. Humans have long been fascinated by human sex differences and formal theories on how human sex is determined date at least to Aristotle (in De ...

Genotype-by-environment interactive effects and conflict solving during gonadal sex differentiation of pejerrey Odontesthes bonariensis, a fish with dual genotypic/environmental sex determination [PDF]

open access: yesBiology of Sex Differences
Background Genotypic (GSD) and environmental (ESD) sex determination coexist in many species of reptiles, fish, and amphibians. Inherited genotypic signals and environmental factors conceivably interact as pro-testis or pro-ovary signals during sex ...

Sex determination without sex chromosomes [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2021
With or without sex chromosomes, sex determination is a synthesis of many molecular events that drives a community of cells towards a coordinated tissue fate. In this review, we will consider how a sex determination pathway can be engaged and stabilized without an inherited genetic determinant.

Androgens by immunoassay and mass spectrometry in children with 46,XY disorder of sex development

open access: yesEndocrine Connections, 2020
Objective: Steroid measurement is a challenge in pediatric endocrinology. Currently, liquid chromatography with tandem mass spectrometry (LC-MS/MS) is considered a gold standard for this purpose. The aim of this study was to co mpare both LC-MS/MS and
