| This means that it interferes with some of the actions of androgens within the body. |
|

|
| But extra maternal androgens are associated with higher rates of aggression and mounting in both sexes, the study finds. |
|
| In utero, female fetuses exposed to excess androgens show masculinization and ambiguous genitalia at birth while male fetuses appear normal. |
|
| Fat cells convert hormones called androgens into estrogen, which raises a woman's risk. |
|
| Its action involves hydroxylations and dehydrations that culminate in aromatization of the A ring of the androgens. |
|
| Both have the effect of reducing the natural production of testosterone and other androgens. |
|
| Administration of glucocorticoids inhibits excessive production of androgens, prevents progressive virilization, and stabilizes renin levels. |
|
| In the brain, aromatization of androgens into estrogens is an essential step in regulating a variety of physiological and behavioral processes. |
|
| Anabolic implants that contain estrogens, androgens, or a combination of the two do not have a direct lipolytic effect on adipose tissue. |
|
| Male gonads, or testes, secrete hormones called androgens, the most important of which is testosterone. |
|
| The estrogen also decreases secretion of gonadotropins by the anterior pituitary, with a consequent decrease in the amount of androgens produced by the ovaries. |
|
| It is well known that gonadal steroids such as progestins, androgens and estrogens are produced by the ovary under the influence of gonadotropins. |
|
| The world of competitive bodybuilding, and Gov. Schwarzenegger, owed its waxy life to androgens. |
|
| When administered to pregnant women, androgens cause virilization of the external genitalia of the female fetus. |
|
| Additionally, we have made progress towards identifying the genes that mediate the effects of androgens on the immune response. |
|
| It is thought to be due to the influence of maternal androgens and resolves spontaneously. |
|
| Oral contraceptives containing a low level of androgens can also contribute to treating women's acne. |
|
|
|
| In addition, we will examine if androgens and estrogens afford their protection against cell death by inhibiting this ER stress. |
|
| However, the body produces some estrogen from other hormones known as androgens through the action of an enzyme called aromatase. |
|
| The research team led by the Professor Richard Sharpe conducted tests on laboratory rats on which they blocked the action of androgens. |
|
| All the products used aim at opposing the effects of androgens, but are of a different nature and act in different ways. |
|
| Small doses of corticosteroids may curb inflammation and suppress the androgens produced by the adrenal glands. |
|
| Aromatisation converts androgens into oestrogens adding to those already circulating in the blood. |
|
| Because this drug also blocks the actions of androgens, it can lead to gynaecomastia and feminisation in male patients. |
|
| Second, androgens make ovarian cells more sensitive to follicle-stimulating hormone or FSH, which promotes follicle growth. |
|
| Kristin received her Bachelor of Science at the University of Toronto at Mississauga in Molecular Biology where she studied the anabolic actions of androgens on myogenic stem cells. |
|
| The stroma which joins all the seminiferous tubules contains LEYDIG cells which produce the androgens essential for spermatogenesis amongst other things. |
|
| Combined with castration, nilutamide exerts a total peripheral antiandrogenic activity by antagonizing the action of androgens of adrenal origin which otherwise may maintain the proliferation of prostatic cancer cells. |
|
| Under the influence of androgens, the voice box, or larynx, grows in both sexes. |
|
| Melanie Gallant, a Grade 12 student at the École François-Buote in Charlottetown, PEI, who identified how a common agricultural herbicide inhibits the production of androgens, the male hormone, in marine fish. |
|
| Exposure of a female fetus or nursing infant to androgens may result in varying degrees of virilization. |
|
| Several other less-active androgens occur naturally. |
|
| Prostate cancer responds to the removal of androgens. |
|
| Oily skin is characterised by the abundance and nature of the sebum excreted at the skin surface by the sebaceous gland, target organ of androgens. |
|
| In the months and years following the appearance of pubic hair, other areas of skin that respond to androgens may develop androgenic hair. |
|
| Insulin increases the action of luteinising hormone on theca cells, resulting in overproduction of androgens. |
|
| Role of androgens in fetal testis development and dysgenesis. |
|
|
|
| Testosterone deficiency can result from defects in testicular production of androgens, at the hypothalamic-pituitary level, or from combined mechanisms. |
|
| Analyses of the animals' hormones have linked these traits to a system influenced by prenatal exposure in females to extra androgens, which are usually masculinizing hormones. |
|
| His lab has devised ingenious ways of gleaning information about how androgens regulate the activity of genes and why they affect certain tissues and not others. |
|
| The main source of oestrogens would be the peripheral aromatisation of androgens into oestrone, which is a weak oestrogen compared with ovarian-derived oestradiol. |
|
| It is believed that high levels of circulating estrogen created by adipose tissue convert androstenedione to estrone, and there is aromatization of androgens. |
|
| The goal of therapy in CAH is to replace the missing glucocorticoids and mineralocorticoids, thereby suppressing ACTH concentrations and normalizing adrenal androgens. |
|
| Androgens could be implicated in the earlier death of males, but recent studies suggest that female mosaicism may enhance lifespan. |
|
| Androgens have been described as any chemical with testosterone-like action. |
|
| Androgens are also responsible for the increased growth in body hair and an increased shedding of keratin, a protein that can block pores and the flow of sebum. |
