Characterization of atrazine-induced gonadal malformations in African clawed frogs (Xenopus laevis) and comparisons with effects of an androgen antagonist (cyproterone acetate) and exogenous estrogen (17beta-estradiol): Support for the demasculinization/feminization hypothesis. [PDF]

open access: yes, 2006
Atrazine is a potent endocrine disruptor that both chemically castrates and feminizes male amphibians. It depletes androgens in adult frogs and reduces androgen-dependent growth of the larynx in developing male larvae.

Changes in plasma steroid hormones and gonadal histology associated with sexual maturation in wild southern hake (Merluccius australis)

open access: yesLatin American Journal of Aquatic Research, 2015
A detailed study of gametes development and characterization of plasma sex steroid hormones during the maturation cycle was performed for the first time in the southern hake (Merluccius australis).

Sexually Dimorphic Roles of Steroid Hormone Receptor Signaling in Gonadal Tumorigenesis [PDF]

open access: yesMolecular Endocrinology, 2003
Sex steroids control cellular phenotypes by binding to receptor proteins that in turn regulate downstream gene expression. They are important tropic factors in hormonally responsive tissues and have been implicated in the pathogenesis of both benign proliferations and malignancies at some of these sites.

Sexual dimorphism in immune function: The role of sex steroid hormones

open access: yesSHS Web of Conferences, 2018
There is evidence of the relation of sex steroid hormones and sexual dimorphism in immune system response to infectious diseases. The aim of this review was to identify the role of sex hormones in immune function and sexual dimorphism of immune reactions.

Rat Ovarian Function Is Impaired during Experimental Autoimmune Encephalomyelitis

open access: yesCells, 2023
Multiple sclerosis (MS) is an autoimmune disease affecting the CNS and occurring far more prevalently in women than in men. In both MS and its animal models, sex hormones play important immunomodulatory roles.

The endocannabinoid system and spermatogenesis

open access: yesFrontiers in Endocrinology, 2013
Spermatogenesis is a complex process in which male germ cells undergo a mitotic phase followed by meiosis and by a morphogenetic process to form mature spermatozoa.

Altered expression of Alzheimer's disease-related proteins in male hypogonadal mice [PDF]

open access: yes, 2012
Age-related depletion of estrogens and androgens is associated with an increase in Alzheimer's disease (AD) brain pathology and diminished cognitive function. Here we investigated AD-associated molecular and cellular changes in brains of aged hypogonadal

The "backdoor pathway" of androgen synthesis in human male sexual development. [PDF]

open access: yes, 2019
Mammalian sex determination (male versus female) is largely controlled by genes, whereas sex differentiation (development of reproductive structures) is largely controlled by hormones. Work in the 20th century indicated that female external anatomy was a
