This study systematically reviewed the use of topical testosterone products such as creams, gels, and patches, finding they effectively raise serum testosterone but pose significant systemic risks like acne and gynecomastia, necessitating careful medical oversight.

This review examines the negative effects of anabolic-androgenic steroid use on the male reproductive system, including impaired testosterone production, sperm production issues, and adverse metabolic consequences without reporting new clinical results.

This source offers an in-depth review of Methandrostenolone, examining its pharmacology, performance-enhancing effects, potential health risks, and legal status in various countries, while emphasizing the scientific evidence surrounding its use and misuse.

This review discusses various sex hormones and related compounds, including estrogens and anabolic steroids, but reports no new findings; it highlights existing literature from 2014 regarding their use and effects.

This study developed a sensitive method using LC-ESI-MS/MS for accurate and reliable measurement of nine steroid hormones in children's serum.

This study highlights that anabolic steroid use is prevalent among bodybuilders in Sergipe, regardless of socioeconomic background, with many experiencing acute and chronic side effects.

In this study, researchers developed a sensitive LC–MS–MS assay to measure 3α-androstanediol levels in rat plasma and observed that testosterone raises these levels via a 5α-reductase pathway.

This study found that among bodybuilder-intended drugs from the black market, 33.8% of labeled products and 52.5% of steroidal oily solutions contained ingredients not matching their labels.

This study reports that testosterone requires conversion to DHT and estradiol for its various actions on external genitalia and bone, influencing lean mass, muscle size, strength, and body fat in hypogonadal males.

The researchers reported a case of falsely elevated testosterone in a teen, due to immunoassay interference, demonstrating that liquid chromatography tandem-mass spectrometry provides more accurate testosterone measurement, emphasizing the need for thorough analysis when clinical results are inconsistent.

This study found that cortisol and corticosterone led to thinning of the epidermis and hair follicle regression in fetal mouse skin, while testosterone promoted differentiation and sebaceous gland development.

Using testosterone-stimulated weanling rats can effectively replace castrated rats for anti-androgen testing, reducing animal stress.

In this study, patients with varying severities of acne, seborrhoea, and hirsutism responded differently to Cyproteronacetate and Ethinyloestradiol treatment, with improvement rates dependent on symptom severity and treatment duration.

High doses of cyclosporine A increase testosterone conversion, possibly boosting hair growth.

This review discusses the potential benefits and adverse effects of testosterone therapy in women with androgen insufficiency, and highlights the need for further research on its long-term safety and effectiveness.

This chapter reviews the clinical effects of androgens like testosterone and its metabolites on various body systems and life stages, but reports no new results.

This report discusses the FDA's rejection of Aveed, a long-acting testosterone injection, due to safety concerns despite divided advisory committee opinions, without presenting new clinical data.

This study found that both cyproterone acetate and spironolactone effectively reduced hair diameter and plasma testosterone levels in hirsute women, with no significant differences between the two treatments.

This study used molecular docking to identify stiripentol as a potential new inhibitor of the SRD5A2 enzyme, which is targeted for treating androgen-related diseases; however, in vivo trials are needed to validate its efficacy.

Detecting steroid esters in cattle hair is inconsistent and influenced by sampling factors.

This study evaluated novel steroids' potential as future hormonal therapies for neuroprotection in glucose disorders, but emphasized that further research is needed to optimize androgen antagonist use in the context of COVID-19 progression.

This study found that spironolactone reduced androgenic hormones in hirsute women but had only marginal effects on hair growth, making it no more advisable than other therapies.

This review discusses recent data on the use of anabolic-androgenic steroids and other steroid compounds and reports no new clinical results.

This study found that LC-MS/MS assays provided more reliable and precise steroid measurements in human serum compared to traditional immunoassays, particularly at lower concentrations.

In this study, prolonged intravenous Fenoterol infusion was associated with intensive hair growth in most patients, although hormonal changes typically linked to such effects were not observed.

This paper details a method for measuring testosterone metabolism into seven androgens using digital autoradiography, which offers high sensitivity and reduces the need for radioactive materials.

This paper discusses the role of steroid sulfatase in hormone-dependent tumors and highlights the development of potent inhibitors, noting the commencement of a phase I trial for one inhibitor in postmenopausal breast cancer patients.

Randomized trials reported that testosterone therapy improved sexual function in postmenopausal women with hypoactive sexual desire disorder, particularly those who had undergone oophorectomy, with reversible and well-tolerated side effects.

This study found that treatment with cyproterone acetate and ethinylestradiol in hirsute women reduced testosterone and androstenedione levels, decreased hair growth, and increased cortisol levels without changing catecholamine excretion.
