Luteal leukocytes are modulators of the steroidogenic process of human mid-luteal cells
(Oxford University Press, 1998)
Flow cytometry analysis of luteal cells revealed that an important proportion of these cells are leukocytes. The percentage of leukocytes was higher in the early (42 ± 4) and late (35 ± 3) luteal phases than in the mid-luteal ...
Ovarian toxicity of environmental contaminants: 50 shades of grey
(2016-01-01)
Exposure to environmental contaminants is thought to be important in the development of adverse effects on reproductive health. While the adverse effects of environmental contaminants on semen quality and testicular function ...
Effect of desialylated human chorionic gonadotropin (hCG) on the bioactivity of rat Leydig cells
(1998)
Human chorionic gonadotropin is a glycoprotein hormone that, like LH, stimulates steroidogenesis in gonadal cells. Using a desialylation process, 95 per cent of the sialic acid residues from an intact standard hCG molecule ...
OxeR1 regulates angiotensin II and cAMP-stimulated steroid production in human H295R adrenocortical cells
(Elsevier Ireland, 2015-02)
Hormone-regulated steroidogenesis and StAR protein induction involve the action of lipoxygenated products. The products of 5-lipoxygenase act on inflammation and immunity by stimulation of a membrane receptor called OxeR1. ...
Prenatal androgen exposure affects ovarian lipid metabolism and steroid biosynthesis in rats
(BioScientifica, 2020-09)
Prenatal androgen exposure affects reproductive functions and has been proposed as an underlying cause of polycystic ovary syndrome (PCOS). In this study, we aimed to investigate the impact of prenatal androgen exposure ...
Steroidogenesis in sheep pregnancy with intrauterine growth retardation by high-altitude hypoxia: effects of maternal altitudinal status and antioxidant treatment
(CSIRO, 2013)
Sheep pregnancy in high-altitude environments frequently involves hypoxia and oxidative stress and causes
intrauterine growth retardation. The adverse effects of altitude on fetal growth can be prevented by the administration ...
Leuprolide acetate reduces both in vivo and in vitro ovarian steroidogenesis in infertile women undergoing assisted reproduction
(ELSEVIER SCIENCE INC, 2008)
Despite the probable inhibitory effects of GnRH analogues on ovarian steroidogenesis in vitro, their association with assisted reproduction protocols shows favorable results. This suggests that there are important differences ...
