Bilateral asymmetry in bullfrog testes and fat bodies: correlations with steroidogenic activity, mast cells number and structural proteins
(2022-04-01)
In seasonal breeders, such as amphibians, testicular functions depend on complex processes that change according to seasonality, including Leydig cell (LC) differentiation and lipid-dependent steroidogenesis, extracellular ...
Mechanism of action of endosulfan as disruptor of gonadal steroidogenesis in the cichlid fish Cichlasoma dimerus
(Elsevier Science Inc, 2016-09)
The organochlorine pesticide endosulfan (ES) is used in several countries as a wide spectrum insecticide on crops with high commercial value. Due to its high toxicity to non-target animals, its persistence in the environment ...
Effects of guanethidine-induced sympathectomy on the spermatogenic and steroidogenic testicular functions of prepubertal to mature rats
(Blackwell Wissenschafts Verlag Gmbh, 2014)
Human chorionic gonadotropin and free beta subunits stimulate phospholipid methylation in intact rat Leydig cells
(1993)
The effect of human chorionic gonadotropin (hCG) on intact Leydig cell phospholipid methylation was
studied. Hormonal stimulation of rat Leydig cells increased the incorporation of[methyl-3H]methionine
into phospholipids ...
Morpho-functional study of human luteal cell subpopulations
(Oxford University Press, 1994)
It has been reported that the mammalian corpus luteum is composed mainly of two subpopulations of luteal cells (large and small) of different morphology and function. The aims of this study were first to characterize ...
Melatonin and testicular function: Characterization of binding sites for 2-[125I]-iodomelatonin in immature rat testes
(Elsevier Inc., 1997)
Melatonin-binding sites in membrane preparation of immature rat testes were demonstrated by utilizing 2-[125I]-iodomelatonin as a radioligand. Binding at these sites was found to be reversible, saturable, specific and of, ...
Male Hypogonadism and Disorders of Sex Development
(Frontiers Media, 2020-04-15)
Disorders of Sex Development (DSD) are congenital anomalies in which there is a discordance between chromosomal, genetic, gonadal and/or internal/external genital sex. In XY individuals, the process of fetal sex differentiation ...
The rodent corpus luteum
(Springer International Publishing Switzerland, 2017)
The corpus luteum is the tissue with most differences among species; rodents have particular features in corpus luteum formation, function and regression. The different types of mammalian corpora lutea can be classified ...
Effects of gestational exposure to di-n-butyl phthalate and mineral oil on testis development of the Mongolian gerbil
(Csiro Publishing, 2018-10-01)
Phthalate esters are endocrine disrupters that can affect the development of the testis in a species-specific manner. However, their interference in the male gonads of the Mongolian gerbil is unknown. The aim of the present ...
Endocrine disruptive action of diclofenac and caffeine on Astyanax altiparanae males (Teleostei: Characiformes: Characidae)
(2020-05-01)
Diclofenac (DCF) and caffeine (CAF) are persistent pharmaceuticals that occur in mixtures in the aquatic ecosystems causing effects in the reproductive physiology of aquatic organisms. This study evaluated the physiological ...
