510-540 / 1000+ resultsresearch Neuroactive steroids induce changes in fetal sheep behavior during normoxic and asphyxic states
Neurosteroids help protect fetal brains from asphyxia damage.
research New Progesterone Esters as 5.ALPHA.-Reductase Inhibitors.
Some new progesterone derivatives are better at blocking testosterone conversion than a common drug.
research Insulin Resistance, Acanthosis Nigricans, and Polycystic Ovaries Associated with a Circulating Inhibitor of Postbinding Insulin Action
A circulating inhibitor caused insulin resistance, but clomiphene improved symptoms.
research The Effects of Perinatal Androgen Deprivation on Locomotor Activity in Male Rats
Blocking androgens in male rats increased estrogen and made them more active.
research Allopregnanolone (AP) induces opioid inhibition of hypothalamo-pituitary-adrenal (HPA) axis responses to interleukin-1β (IL-1β) in pregnancy
Allopregnanolone and opioids together reduce stress hormone responses during pregnancy.
research Autologous platelet-rich plasma improves the endometrial thickness and live birth rate in patients with recurrent implantation failure and thin endometrium
research The biochemical and phenotypic characterization of females homozygous for 5 alpha-reductase-2 deficiency.
Females with 5 alpha-reductase-2 deficiency have less body hair, no acne, normal fertility, and delayed menarche.
research Atherogenesis: Estrogen Induction of Polysialylated nCAM (PSA-nCAM) Blocks Monocyte Capture by Vascular Endothelial Cells
Estrogen helps prevent artery plaque by stopping monocyte capture in blood vessels.
research EVALUATION OF FETUIN-A LEVEL IN POLYCYSTIC OVARY SYNDROME AND ITS ASSOCIATION WITH ASPROSIN AND SOME BIOCHEMICAL PARAMETERS.
Fetuin-A levels are higher in PCOS patients, suggesting it may play a role in the condition.
research Changes in expression of the neuropeptide Y Y1 receptor gene in the medial amygdala of transgenic mice during pregnancy and after delivery
Pregnancy-related hormone changes affect Y1 receptor gene expression in mice.
research Association between the serum estrone-to-estradiol ratio and parameters related to glucose metabolism and insulin resistance in women with polycystic ovary syndrome
Higher estrone-to-estradiol ratios are linked to worse glucose metabolism and insulin resistance in women with PCOS.
research 5α-reduction of epitestosterone is catalysed by human SRD5A1 and SRD5A2 and increases androgen receptor transactivation
5α-reductases increase epitestosterone's effect on androgen receptors.
research Genome-wide shifts in gene expression induced in theca-interstitial cells by inflammatory stimuli
African American women have a higher risk of preterm delivery than Caucasian women, and inflammatory stimuli affect gene expression in cells related to PCOS, showing a heightened inflammatory state in women with PCOS.
research Equine 5α-reductase activity and expression in epididymis
The equine epididymis mainly uses type 1 5α-reductase, and both finasteride and dutasteride can inhibit its activity.
research Neonatal finasteride administration alters hippocampal α4 and δ GABAAR subunits expression and behavioural responses to progesterone in adult rats
research Study on Changes of 19 Steroids in Plasma From 9 Diagnosed Patients With P450 Oxidoreductase Deficiency
Certain hormone levels can help diagnose P450 oxidoreductase deficiency.
research Estrogens
research PLASMA C19 STEROID SULPHATE LEVELS AND INDICES OF ANDROGEN BIOAVAILABILITY IN FEMALE PATTERN ANDROGENIC ALOPECIA
Women with female pattern hair loss have higher levels of certain androgens, suggesting increased androgen exposure to hair follicles.
research Involvement of neurosteroids in the control of prolactin secretion in sheep under basal, stressful and pregnancy conditions
Neurosteroids affect prolactin levels in sheep differently depending on stress and pregnancy conditions.
research Maternal androgen excess induces cardiac hypertrophy and left ventricular dysfunction in female mice offspring
High levels of male hormones in pregnant mice cause heart enlargement and poor heart function in their female babies.
research Sex-dependent effect of a low neurosteroid environment and intrauterine growth restriction on fetal guinea pig brain development.
Reduced neurosteroids and growth issues can harm fetal brain development, especially in males.
research Central Opioid Inhibition of Neuroendocrine Stress Responses in Pregnancy in the Rat Is Induced by the Neurosteroid Allopregnanolone
In late pregnancy, allopregnanolone reduces stress responses in rats by affecting brain chemicals.
research Effects of aromatase inhibitors on human osteoblast and osteoblast-like cells: A possible androgenic bone protective effects induced by exemestane
Exemestane may protect bones by stimulating osteoblast growth through androgen-related pathways.
research Testosterone Reduces Tight Junction Complexity and Down-regulates Expression of Claudin-4 and Occludin in the Endometrium in Ovariectomized, Sex-steroid Replacement Rats
Testosterone makes the connections in the uterus lining simpler and lowers certain protein levels, which might lead to infertility.
research Paxillin regulates androgen receptor expression associated with granulosa cell focal adhesions
Paxillin may help manage androgen-related disorders like PCOS by stabilizing androgen receptor proteins.
research Cloning, computational analysis and expression profiling of steroid 5 alpha-reductase 1 (SRD5A1) gene during reproductive phases and ovatide stimulation in endangered catfish, Clarias magur
The research identified and described a gene important for hormone conversion in endangered catfish, which varies in activity during different reproductive stages and after hormone treatment.
research Finasteride delays the onset of maternal behavior in primigravid rats
Finasteride slows down motherly behavior in first-time pregnant rats.
research More about X‐linked testicular feminization of the mouse as a noninducible (is) mutation of a regulatory locus: 5α‐androstan‐3α‐17ß‐diol as the true inducer of kidney alcohol dehydrogenase and ß‐glucuronidase
A specific metabolite, not a receptor protein, triggers the production of certain kidney enzymes, but this process is disrupted in mice with a mutation causing testicular feminization.
research Design, synthesis and structure-activity relationships studies on steroidal aromatase and 5α-reductase inhibitors as anti-tumors
Modified steroidal inhibitors showed promise in treating hormone-dependent cancers.
