Mapping and Validation of the Major Sex-Determining Region in Nile Tilapia (Oreochromis niloticus L.) Using RAD Sequencing [PDF]

open access: yes, 2013
Sex in Oreochromis niloticus (Nile tilapia) is principally determined by an XX/XY locus but other genetic and environmental factors also influence sex ratio.

Clinical and Laboratorial Features That May Differentiate 46,XY DSD due to Partial Androgen Insensitivity and 5α-Reductase Type 2 Deficiency

open access: yesInternational Journal of Endocrinology, 2012
The aim of this study was to search for clinical and laboratorial data in 46,XY patients with ambiguous genitalia (AG) and normal testosterone (T) synthesis that could help to distinguish partial androgen insensitivity syndrome (PAIS) from 5α-reductase ...

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 ...

Histological and transcriptomic effects of 17α-methyltestosterone on zebrafish gonad development

open access: yesBMC 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.

UBE2I stimulates female gonadal differentiation in chicken (Gallus gallus) embryos

open access: yesJournal 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 ...

Pathways to Sex-based Differentiation in Criminal Court Sentencing [PDF]

open access: yes, 2003
Using a matched sampling method, this research examined the process of sex-based differentiation in sentencing outcomes for 194 men and 194 women, sentenced over a seven-year period in Christchurch, New Zealand. Consistent with past research, our results

Long-Term Follow-Up of Patients with 46,XY Partial Gonadal Dysgenesis Reared as Males

open access: yesInternational 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.

Role of DNA Methylation in Sexual Differentiation of Neurochemical Phenotype in the Brain [PDF]

open access: yes, 2023
Sex differences in the brain underlie sex-specific behaviors and physiological processes, and may help to explain male- or female-biased neuropsychiatric disorders.
