Mismatches between the genetic and phenotypic sex in the wild Kou population of Nile tilapia Oreochromis niloticus [PDF]

PeerJ, 2019
Sex determination and sex chromosomes can be very diverse between teleost species. The group of tilapias shows a polymorphism in sex determination not only between closely related species but also between domestic strains within a species.

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]

Biology 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 ...

Evidence for Variation in the Genetic Basis of Sex Determination in Brook Stickleback (Culaea inconstans) [PDF]

Ecology and Evolution
The genetic basis of sex determination is typically conserved within species if not within broader lineages. For example, within the stickleback family (Gasterosteidae), AmhY has been identified as a master sex‐determination (MSD) gene in multiple ...

Complete androgen insensitivity syndrome and risk of gonadal malignancy: systematic review [PDF]

Annals of Pediatric Endocrinology & Metabolism, 2021
Complete androgen insensitivity syndrome (CAIS) is a rare condition characterized by 46,XY karyotype, female external genitalia, absence of uterus, and testes located intra-abdominally, in the inguinal ring or in the labia majora.

Sex dimorphism of weight and length at birth: evidence based on disorders of sex development

Annals of Human Biology, 2022
Background Males have higher weight and length at birth than females. Aim To verify the influence of the Y chromosome and the action of intrauterine androgens on weight and length at birth of children with Disorders of Sex Development (DSD). Subjects and

Molecular characterization and expression profiling of transformer 2 and fruitless-like homologs in the black tiger shrimp, Penaeus monodon [PDF]

PeerJ, 2022
Transformer 2 (tra 2) and fruitless (fru) genes have been proven to play a key role in sex determination pathways in many Arthropods, including insects and crustaceans. In this study, a paralog of P. monodon tra 2 (Pmtra 2), P. monodon ovarian associated

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

Endocrine 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
