This review discusses the role of neurosteroids and androgens throughout different life stages, noting the potential disruptions caused by 5α-reductase inhibitors like finasteride, but no new clinical results are reported.

This review discusses the influence of oestrogens on various skin components and highlights their modulatory roles and receptor pathways, but it reports no new clinical results.

Male and female mice have different skin thickness, and hormones affect their skin and hair growth differently.

This study found that both finasteride and a new steroidal compound, PM-9, competitively inhibit the 5α-reductase enzyme in Penicillium crustosum broth.

This review discusses the influence of androgens on opioid-mediated effects and calls for further research into their role in sex differences and potential therapeutic options for chronic pain and substance use disorders.

This study found that while testosterone administration reduced myocardial damage in gonadectomized rats after ischemia/reperfusion injury, Finasteride led to greater improvements, whereas 4-hydroxyandrostenedione worsened outcomes.

This study found that gonadal steroid hormones influence alopecia areata in C3H/HeJ mice, with estradiol promoting progression and dihydrotestosterone conferring resistance to disease onset.

This study found that castration increased 5 alpha-reductase activity in the sebaceous glands of male hamsters, but administering testosterone propionate or 5 alpha-dihydrotestosterone inhibited this effect.

This study found that finasteride treatment in adult hamsters led to significant testicular alterations and reduced spermatogenesis compared to untreated controls.

In this case report, authors described a pet golden hamster with a confirmed adrenocortical adenocarcinoma, where laboratory testing and diagnostic imaging enabled antemortem diagnosis, despite the species' rarity for these procedures.

Young and adult hamsters both respond similarly to testosterone and finasteride treatments, but young hamsters aren't good for testing the inhibitory activity of a specific enzyme.

This study found that finasteride administration in hamsters led to significant spermatogenesis reduction and seminiferous tubule atrophy compared to the control group.

This study observed that 5α‐dihydrotestosterone increased pigmentation in certain skin areas of male Syrian hamsters, while estradiol decreased melanocyte numbers and counteracted the androgen-induced pigmentation effects.

Male hormones control a specific gene in hamster skin, with different hormones having varying effects.

This study found that testosterone propionate increased hair mass in female hamsters' flank organs, while cyproterone acetate applied topically reduced androgen-stimulated hair in a dose-dependent manner.

This study found that the androgen precursors DHEA and androstenedione stimulated androgen-sensitive parameters in the sebaceous glands of the skin in castrated male hamsters.

This study aimed to evaluate the potential use of ovariectomized mice as a model for postmenopausal female pattern hair loss, but it reports no new results.

In this study, researchers discovered that the MafB gene, which is important for macrophage differentiation, shows high expression in the pancreas and is influenced by sex steroids, with varied expression patterns in hamster tissues and during reproductive phases.

GABAergic steroid precursors reduce ethanol withdrawal symptoms in certain mice.

This study on rats found that adrenalectomy was associated with increased hair loss compared to sham adrenalectomy, where one adrenal was left intact.

In this study, finasteride treatment for 56 days in adult rats led to sloughing of immature germinal cells and reduced sperm content in the epididymis, indicating its importance for maintaining spermatogenesis.

This study found that hamster sebaceous glands have high affinity binding sites for dihydrotestosterone, with competition from other steroids indicating specific binding characteristics.

This study found that subcutaneous isotretinoin in male hamsters reduced sebaceous gland size without affecting other androgen-dependent skin structures, while etretinate had no effect.

This study observed that gender-affirming hormone therapy differentially affects metabolism in mice, with the specific metabolic impacts dependent on the type of hormonal treatment used.

In this study using rats, finasteride-induced DHT deficiency led to morphological changes in seminiferous tubules, linked with altered junctional protein expression, potentially impairing fertility.

In this study, patients with testicular feminization syndrome showed limited anabolic responsiveness to dihydrotestosterone, potentially due to reduced affinity of nuclear receptor sites for androgenic steroids rather than defective testosterone conversion.

This study found that administering testosterone to ovariectomized female rats decreased endometrial tight junction complexity and expression of specific proteins, potentially affecting embryo implantation.

This study found a significant association between patients' sex of rearing and external genitalia in those with gonadal dysgenesis, while noting lower testosterone levels compared to controls.

This study found no correlation between clinical signs and sex steroid levels in ferrets with hyperadrenocorticism and noted that androstenedione was elevated in many cases.

This study observed that the compound EM-402 reduced 5α-reductase activity and sebaceous gland size in the flank organs and ears of hamsters, indicating potent localized anti-androgenic effects without systemic action.
