Insights into Gonadal Sex Differentiation Provided by Single-Cell Transcriptomics in the Chicken Embryo.

open access: yesCell Reports, 2020
Although the genetic triggers for gonadal sex differentiation vary across species, the cell biology of gonadal development was long thought to be largely conserved.

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

The “IAG-Switch”—A Key Controlling Element in Decapod Crustacean Sex Differentiation

open access: yesFrontiers in Endocrinology, 2020
The androgenic gland (AG)–a unique crustacean endocrine organ that secretes factors such as the insulin-like androgenic gland (IAG) hormone—is a key player in crustacean sex differentiation processes.

Nucleoporin107 mediates female sexual differentiation via Dsx

open access: yeseLife, 2022
We recently identified a missense mutation in Nucleoporin107 (Nup107; D447N) underlying XX-ovarian-dysgenesis, a rare disorder characterized by underdeveloped and dysfunctional ovaries.

10,000 social brains: Sex differentiation in human brain anatomy

open access: yesScience Advances, 2020
Population variability in social lifestyle is reflected in brain morphology in sex-dependent ways. In human and nonhuman primates, sex differences typically explain much interindividual variability.

Effects of the Thyroid Endocrine System on Gonadal Sex Ratios and Sex-Related Gene Expression in the Pufferfish Takifugu rubripes

open access: yesFrontiers in Endocrinology, 2021
To examine the effect and mechanism of thyroid hormone on gonadal sex differentiation, Takifugu rubripes larvae were treated with goitrogen (methimazole, MET, 1000 μg/g), and thyroxine (T4, 2nM) from 25 to 80 days after hatching (dah).

Sex Determination and Sex Differentiation

open access: yesJournal of Forensic Dental Sciences, 2021
Sex determination is arguably the most defining moment of our lives, the point where we inherit X or Y chromosome from our father. This initiates a cascade of events that sets in a train of morphological changes, genetic regulations and molecular mechanisms.

Evolution of plant reproduction: from fusion and dispersal to interaction and communication [PDF]

open access: yes, 2009
Based on the existing data concerning the evolution of the sexual reproduction, it is argued that the processes of sex differentiation and interactions play a key role in evolution. From the beginning environment and organism are unified.

Putative Role of CFSH in the Eyestalk-AG-Testicular Endocrine Axis of the Swimming Crab Portunus trituberculatus

open access: yesAnimals, 2023
It has been shown in recent studies that the crustacean female sex hormone (CFSH) plays a crucial role in the development of secondary sexual characteristics in Decapoda crustaceans. However, research on the function of CFSH in the eyestalk-AG-testicular

Minireview: Sex Differentiation [PDF]

open access: yesEndocrinology, 2001
Mammalian sex differentiation is a hormone-dependent process in the male following the determination of a testis from the indifferent gonad through a cascade of genetic events. Female sex differentiation is not dependent on ovarian hormones, yet there is evidence that members of the Wnt family of developmental signaling molecules play a role in ...
