Research
810-840 / 1000+ results research Puberty in Boys: Correlation of Plasma Levels of Gonadotropins (LH, FSH), Androgens (Testosterone, Androstenedione, Dehydroepiandrosterone and Its Sulfate), Estrogens (Estrone and Estradiol) and Progestins (Progesterone and 17-Hydroxyprogesterone)
Hormone levels change during puberty, leading to physical developments like pubic hair and voice changes.
research Testosterone Metabolism in the Skin
Increased DHT formation in skin can cause hair loss, acne, and excessive hair growth, and antiandrogens might treat these conditions.
research Obstructive Sleep Apnea Due to Endogenous Testosterone Production in a Woman
Removing a testosterone-producing tumor cured a woman's sleep apnea and other symptoms.
research 3α-androstanediol, but not testosterone, attenuates age-related decrements in cognitive, anxiety, and depressive behavior of male rats
3α-androstanediol helps reduce age-related cognitive and mood declines in male rats, unlike testosterone.
research The effect of finasteride, a 5 alpha-reductase inhibitor, on scalp skin testosterone and dihydrotestosterone concentrations in patients with male pattern baldness.
Finasteride reduces scalp DHT levels, potentially treating male pattern baldness.
research Effect of 5α-Dihydrotestosterone and Testosterone on Apoptosis in Human Dermal Papilla Cells
High levels of testosterone and 5α-DHT can lead to cell death in cells important for hair growth.
research Cellular actions of testosterone in vascular cells: Mechanism independent of aromatization to estradiol
Testosterone affects vascular cells directly without converting to estradiol.
research Testosterone alters iron metabolism and stimulates red blood cell production independently of dihydrotestosterone
Testosterone boosts red blood cell production and changes iron metabolism without needing dihydrotestosterone.
research Central 5-alpha reduction of testosterone is required for testosterone's inhibition of the hypothalamo-pituitary–adrenal axis response to restraint stress in adult male rats
Testosterone needs to be converted to DHT to reduce stress response in male rats.
research Androgen-Dependent Beard Dermal Papilla Cells Secrete Autocrine Growth Factor(s) in Response to Testosterone Unlike Scalp Cells
Beard cells, unlike scalp cells, produce growth factors in response to testosterone, which may explain differences in hair growth.
research Effects of Ginseng Rhizome and Ginsenoside Ro on Testosterone 5α-Reductase and Hair Re-growth in Testosterone-treated Mice
Ginseng, especially red ginseng, may help regrow hair and block a hair loss-related enzyme.
research Measurement of Cortisol and Testosterone in Hair of Obese and Non-Obese Human Subjects
Hair hormone levels can indicate obesity-related changes and are useful for research and clinical practice.
research Differential Suppression of Testosterone and Estradiol in Hirsute Women With the Superactive Gonadotropin-Releasing Hormone Agonist Leuprolide*
Leuprolide effectively reduces hair growth in hirsute women at higher doses.
research A combined regimen of cyproterone acetate and testosterone enanthate as a potentially highly effective male contraceptive.
The combination of cyproterone acetate and testosterone enanthate is highly effective in preventing sperm production and could be a good reversible male contraceptive.
research Biochemical Roles of Testosterone and Epitestosterone to 5α-Reductase as Indicators of Male-Pattern Baldness
High testosterone to epitestosterone ratio in hair could predict male-pattern baldness.
research Overexpression of aldo-keto reductase 1C3 (AKR1C3) in LNCaP cells diverts androgen metabolism towards testosterone resulting in resistance to the 5α-reductase inhibitor finasteride
Too much AKR1C3 enzyme causes resistance to finasteride by increasing testosterone.
research Aromatase-independent testosterone conversion into estrogenic steroids is inhibited by a 5α-reductase inhibitor
Combining 5α-reductase and aromatase inhibitors may better reduce estrogen levels.
research Testosterone 5.ALPHA.-Reductase Inhibitory Active Constituents of Piper nigrum Leaf
Black pepper leaf extract contains compounds that can block testosterone effects and promote hair growth.
research Cinnamomi Cortex (Cinnamomum verum) Suppresses Testosterone-induced Benign Prostatic Hyperplasia by Regulating 5α-reductase
Cinnamomi cortex may help treat prostate enlargement by reducing related proteins.
research Testosterone metabolism in the skin. A review of its function in androgenetic alopecia, acne vulgaris, and idiopathic hirsutism including recent studies with antiandrogens
Testosterone affects hair loss, acne, and excessive hair growth, and antiandrogens can help treat these conditions.
research Anabolic effects of testosterone are preserved during inhibition of 5α-reductase
Testosterone can build muscle and bone without enlarging the prostate when a specific enzyme is blocked.
research Normalization of testosterone levels using a low estrogen-containing oral contraceptive in women with polycystic ovary syndrome.
Loestrin effectively normalizes testosterone levels and improves PCOS symptoms with minimal side effects.
research Hair removal in hirsute women with normal testosterone levels: a randomized controlled trial of long-pulsed diode laser vs. intense pulsed light
Both intense pulsed light and long-pulsed diode laser effectively reduced facial hair in women, with no significant difference in satisfaction after 6 months, but intense pulsed light was more painful.

research Inhibition of Rat 5α-Reductase Activity and Testosterone-Induced Sebum Synthesis in Hamster Sebocytes by an Extract ofQuercus acutissimaCortex
An extract from Quercus acutissima bark was found to reduce sebum production and block an enzyme linked to acne.
research Testosterone therapy in women: Myths and misconceptions
Testosterone therapy is beneficial for women's health and does not cause masculinization or liver damage, and it protects the heart and breasts.
