This narrative review concludes that long-term randomized controlled trials are needed to establish clear guidelines for testosterone therapy in women, given the lack of FDA-approved formulations and the variable quality of current treatments.

This case study described a girl with vitamin D-dependent rickets type 2A who developed long-standing tertiary hyperparathyroidism, yet this did not hinder the healing of her rickets or normalization of hypophosphatemia; high doses of intravenous calcium were pivotal for recovery.

This study found that combining oral testosterone with dutasteride increased testosterone bioavailability in hypogonadal men while suppressing dihydrotestosterone levels over a 28-day period.

In this study, co-administration of finasteride with oral testosterone undecanoate in young men with induced hypogonadism had no significant effect on serum testosterone or dihydrotestosterone levels, likely due to TU's unique absorption route.

In this retrospective study of eight Saudi children with hereditary vitamin D resistant rickets, researchers observed that adjunctive cinacalcet appeared safe and showed initial promise in improving serum PTH levels, though further investigation is needed to confirm its efficacy.

This review outlines the major health consequences of anabolic-androgenic steroid abuse, with a focus on sexual and reproductive issues, and suggests management prioritizes cessation and relapse prevention due to lack of robust randomized trials.

The study found that prolactin expressed in human scalp hair follicles acts as an autocrine modulator, inhibiting hair growth and promoting hair follicle regression, which may contribute to hair loss in hyper-prolactinemia patients.

This review discusses the cardiovascular risks associated with anabolic-androgenic steroid use and reports that, despite known toxic effects, further research is needed to clarify the causality of these risks.

This review discusses the effects of thyroid hormone on the skin and explores the potential for using it to treat skin diseases, but reports no new clinical results.

This review presents substantial evidence supporting testosterone use for hypoactive sexual desire disorder in postmenopausal women, but notes safety concerns with off-label prescribing due to lack of approved formulations.

This review discusses the negative effects of anabolic androgenic steroids on various organ systems in men and reports no new results, highlighting the need for physician awareness.

This review discusses the impact of testosterone therapy on postmenopausal women's sexual function and well-being but notes a lack of long-term safety studies and debates on defining androgen insufficiency.

This review discusses the possible impacts of prolactin on skin conditions like psoriasis, alopecia, and stress-related dermatoses, emphasizing the need for further research to explore its therapeutic potential.

This study found that intravaginal testosterone significantly improved sexual satisfaction and reduced dyspareunia in postmenopausal women using aromatase inhibitors, with no effect on urinary incontinence.

A young man with an eating disorder had a life-threatening adrenal crisis due to an autoimmune condition, highlighting the need for better education on managing hormone treatments.

This study found that testosterone therapy can enhance sexual satisfaction and mood in surgically menopausal women on oestrogen, though ongoing monitoring and research are needed to assess long-term safety and effects in other groups.

This study found that a regimen combining cyproterone acetate and testosterone buciclate induced reversible azoospermia in bonnet monkeys, highlighting its potential as an effective male contraceptive.

In this case report, researchers describe a 44-year-old woman with refractory patch alopecia areata achieving complete hair regrowth using a multi-modal approach of systemic and topical cholecalciferol with microneedling, although systemic vitamin D repletion remains a significant confounder.

This article reviews the use of cross-sex hormonal therapy in transmen and reports that it is reasonably safe, suggesting monitoring should be frequent initially but can be less frequent over time.

In this study, mutations in the vitamin D receptor were identified in Brazilian children with rickets and alopecia, leading to impaired receptor activation and reduced 24-hydroxylase expression.

This review discusses the use of testosterone therapy for low libido in women, noting mixed evidence on breast cancer risk and a lack of long-term safety data.

This report highlights a case where a woman's use of the dopamine agonist pramipexole for Parkinson's disease was associated with hair loss, which improved after discontinuing the drug.

This article reviews botulinum toxin use in men, focusing on anatomical and treatment differences, with no new clinical results.

This review examines existing research on transdermal testosterone for treating hypoactive sexual desire disorder, suggesting it improves female sexual function with minimal side effects but highlights the need for more long-term safety data.

This review discusses the role of glucocorticoids in treating severe inflammatory disorders and highlights their potential adverse effects, recommending dosage management to minimize these risks; no new clinical results are reported.

This study identified two distinct VDR gene mutations among Lebanese families with hereditary vitamin D-resistant rickets, noting varied treatment responses and promising outcomes despite severe phenotypes.

This review examines the scientific evidence on the short-term safety of testosterone therapy for treating hypoactive sexual desire disorder in women, without presenting new clinical results.

In this animal study, administering testosterone alongside a 5α-reductase inhibitor counteracted testosterone's effects on prostate enlargement while preserving its beneficial effects on muscle and bone.

This study found that injectable platelet-rich fibrin (i-PRF) enhances hair follicle regeneration in vitro by promoting human dermal papilla cell proliferation, migration, and trichogenic inductivity, with varying effects depending on concentration.

In this study, the authors reported that taking 20 mg or more of biotin can interfere with thyroid function tests, potentially leading to false diagnoses of conditions like Grave's disease.
