Sex steroid dynamics during embryogenesis and sexual differentiation in Eurasian perch, Perca fluviatilis [PDF]
, 2007 It is widely accepted that sex steroid hormones play an important and a specific role during the process of sex differentiation in fish. In order to describe the role of the three main sex steroid hormones (testosterone--T, 17beta-estradiol--E2 and ...

Histological and transcriptomic effects of 17α-methyltestosterone on zebrafish gonad development
BMC Genomics, 2017 Background Sex hormones play important roles in teleost ovarian and testicular development. In zebrafish, ovarian differentiation appears to be dictated by an oocyte-derived signal via Cyp19a1a aromatase-mediated estrogen production.

Long-Term Follow-Up of Patients with 46,XY Partial Gonadal Dysgenesis Reared as Males
International Journal of Endocrinology, 2014 Background/Aims. Studies on 46,XY partial gonadal dysgenesis (PGD) have focused on molecular, gonadal, genital, and hormone features; little is known about follow-up. Our aim was to analyze long-term outcomes of PGD. Methods.

UBE2I stimulates female gonadal differentiation in chicken (Gallus gallus) embryos
Journal of Integrative Agriculture, 2021 Without known analogous sex-determining factors like SRY (sex determining region Y) in mammals, the chicken (Gallus gallus) sex determination mechanism still remains unclear, which highly restricts the biological research on chicken development and ...

Using conventional F-statistics to study unconventional sex-chromosome differentiation. [PDF]
, 2017 Species with undifferentiated sex chromosomes emerge as key organisms to understand the astonishing diversity of sex-determination systems. Whereas new genomic methods are widening opportunities to study these systems, the difficulty to separately ...

A genetic basis for a postmeiotic X versus Y chromosome intragenomic conflict in the mouse. [PDF]
, 2012 Intragenomic conflicts arise when a genetic element favours its own transmission to the detriment of others. Conflicts over sex chromosome transmission are expected to have influenced genome structure, gene regulation, and speciation.

Sex Differences in Recombination in Sticklebacks. [PDF]
, 2018 Recombination often differs markedly between males and females. Here we present the first analysis of sex-specific recombination in Gasterosteus sticklebacks. Using whole-genome sequencing of 15 crosses between G. aculeatus and G.
