In this randomized study of male contraceptive regimens, adding finasteride did not significantly enhance spermatogenesis suppression compared to the control group.

This review details the development of the alpha-helix model for protein structure proposed by Pauling and Corey and confirms its validity through X-ray studies of myoglobin and lysozyme.

In this study, divalproex sodium extended-release was found to be more tolerable and preferred by patients compared to the delayed-release formulation, with improved seizure control and psychiatric symptom relief.

This study uses cryo-electron microscopy to reveal how androgen receptor forms a non-obligate dimer to bind DNA, with implications for prostate cancer development.

This study observed that male human hair follicles metabolized dehydroepiandrosterone (DHA) more intensively than skin did and found altered DHA metabolism in follicles from balding individuals.

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

This study found that combining red light therapy with oral beta-carotene significantly improved photoaging treatment outcomes compared to red light therapy alone, with Group A showing a 56.12% reduction in photoaging scores over 12 weeks versus 44.78% in Group B.

This paper discusses the management of pregnancy in a carrier of the Donohue mutation and reports no new clinical findings.

This study describes the molecular conformation and intermolecular interactions in the crystalline structure of the compound C24H31BrO4.

This review outlines the complexities of understanding DHT biosynthesis and metabolism in the human prostate and reports no new findings, emphasizing the need for further research into the pathways involved.

This study explains that while trichothiodystrophy and xeroderma pigmentosum share genetic defects, TTD patients primarily exhibit issues in transcription initiation, not the increased skin cancer risk seen in XP.

In this study, 50 mg/day of DHEA supplementation in postmenopausal women did not significantly improve sexual function compared to a placebo over 26 weeks.

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 study found genetic variations, including de novo variants and copy number variations, that may be associated with phenotypic discordance in monozygotic twins with various clinical conditions.

This study found that a 6-week treatment with both brands of biotin and dexpanthenol significantly improved hair fall count and hair density in people with diffuse pattern hair loss, with no significant difference between the two brands.

This study found that recruiting healthy naturally menopausal women for a DHEA therapy trial was challenged by concerns about hormonal treatments and time constraints, impacting study feasibility.

This study found that canine dermal papilla cells and fibroblasts metabolize androgens differently than human hair follicle cells, indicating species-specific differences in androgen metabolism.

This study found that dutasteride more effectively reduced serum dihydrotestosterone levels than finasteride in patients with benign prostatic hyperplasia.

This study found that UV radiation exposure increased protein elution and altered protein characteristics in hair fibers, suggesting environmental factors impact hair shaft proteins.

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.

In this study, researchers identified a recurrent nonsense mutation, c.409C>T (p.Arg137*), in the COL7A1 gene through whole exome sequencing in a family with autosomal recessive dystrophic epidermolysis bullosa, demonstrating the importance of this method for diagnosing genetically complex conditions.

This study found that the GPRC6A-Duox1 signaling pathway influences hair cycle progression and testosterone-mediated hair loss in mice, suggesting that disruption of this pathway leads to resistance against testosterone-induced hair loss and longer anagen phase duration.

This abstract contains fragmented and promotional text about various topics, including Hondrostrong and unrelated products, without presenting any new research findings.

This study found that anionic HSES achieved high complexation efficiencies with various steroids, significantly enhancing their solubility, while specific β-cyclodextrin thioethers showed selective binding to testosterone and estradiol.

This review found no evidence that DHEA improves quality of life or decreases menopausal symptoms in peri- and postmenopausal women, but it may slightly enhance sexual function compared to placebo.

This abstract reviews testosterone supplementation with and without a dual 5α-reductase inhibitor on fat-free mass in men with suppressed testosterone production and reports no new research findings.

This article reviews the contraceptive agent Depo-Provera, discussing its effectiveness, potential side effects, and safety concerns, but reports no new clinical results.
