Gonadal Steroid Hormones Maintain the Stress-Induced Acetylcholine Release in the Hippocampus: Simultaneous Measurements of the Extracellular Acetylcholine and Serum Corticosterone Levels in the Same Subjects

Endocrinology, 2007
To examine the role of gonadal steroid hormones in the stress responses of acetylcholine (ACh) levels in the hippocampus and serum corticosterone levels, we observed these parameters simultaneously in intact, gonadectomized, or gonadectomized steroid ...

Steroid Hormones During Embryonic Development in Japanese Quail: Plasma, Gonadal, and Adrenal Levels

Poultry Science, 2001
The purpose of this experiment was to measure plasma, gonad, and adrenal steroid hormones during embryonic and early posthatch development in Japanese quail. Blood plasma samples were collected from male and female Japanese quail embryos at 2-d intervals

Bio- and Immunoactive Luteinizing Hormone in Negative Feedback Action of Gonadal Steroids

Folia Endocrinologica Japonica, 1985
To clarify the possible intervention of gonadal steroids on the secretion of bioactive LH from the pituitary, the levels of plasma LH were measured by in vitro bioassay as well as radioimmunoassay, and their changes in specific endocrine conditions were investigated.

Vertebrate endocrine disruptors induce sex-reversal in blue mussels [PDF]

Scientific Reports
Mollusks are the second most diverse animal phylum, yet little is known about their endocrinology or how they respond to endocrine disrupting compound (EDC) pollution. Characteristic effects of endocrine disruption are reproductive impairment, skewed sex

Elevated plasma corticosterone decreases yolk testosterone and progesterone in chickens: linking maternal stress and hormone-mediated maternal effects. [PDF]

PLoS ONE, 2011
Despite considerable research on hormone-mediated maternal effects in birds, the underlying physiology remains poorly understood. This study investigated a potential regulation mechanism for differential accumulation of gonadal hormones in bird eggs ...

The Crosstalk between Melatonin and Sex Steroid Hormones

Neuroendocrinology, 2021
Melatonin, an indolamine mainly released from the pineal gland, is associated with many biological functions, namely, the modulation of circadian and seasonal rhythms, sleep inducer, regulator of energy metabolism, antioxidant, and anticarcinogenic ...

Adrenal, Gonadal and Peripherally Steroid Changes in Response to Extreme Physical Stress for Characterizing Load Capacity in Athletes

Metabolites, 2022
Athletes are often exposed to extreme physical stress during training or competitions. The consequent activation of the hypothalamus–hypophysis–adrenal (HPA) axis results in intensified steroid hormone production in the adrenal cortex.
