840-870 / 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 Supplementation for Aging-Associated Sarcopenia
Testosterone supplements can increase muscle mass and strength in older men with low levels, but long-term effects and risks need more research.
research Safety of testosterone treatment in postmenopausal women
Testosterone therapy seems safe for postmenopausal women for a few years, but more research is needed for long-term effects.
research Exogenous Testosterone Alone or With Finasteride Does Not Improve Measurements of Cognition in Healthy Older Men With Low Serum Testosterone
Testosterone with or without finasteride doesn't improve thinking skills in older men with low testosterone.
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 Potential adverse effects of long-term testosterone therapy
Long-term testosterone therapy can cause hormone suppression, affect prostate and heart health, and alter physical characteristics, but does not increase prostate cancer risk and needs more research for full risk assessment.
research Physical Changes, Laboratory Parameters, and Bone Mineral Density During Testosterone Treatment in Adolescents with Gender Dysphoria
Testosterone treatment effectively causes male physical development in transgender male adolescents but may lead to side effects like acne, higher BMI and blood pressure, lower good cholesterol, and decreased bone density.
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 The use of a transscrotal testosterone delivery system in the treatment of patients with weight loss related to human immunodeficiency virus infection
The transscrotal testosterone patch normalizes hormone levels in men with AIDS and weight loss but does not improve weight, body mass, or quality of life.
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 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 Genetic predictors of testosterone and their associations with cardiovascular disease and risk factors: A Mendelian randomization investigation
Testosterone is linked to cardiovascular risk factors and stroke, but its exact role is unclear.
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 Safety of testosterone use in women
Short-term testosterone therapy in women seems safe with few mild side effects, but long-term effects need more research.
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 Testosterone therapy for sexual dysfunction in postmenopausal women
Testosterone therapy can help improve sexual desire and function in postmenopausal women but may cause side effects and is not FDA-approved for this use.
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 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.
