810-840 / 1000+ resultsresearch Defects in Androgen Biosynthesis Causing 46,XY Disorders of Sexual Development
Genetic defects in androgen production are linked to male developmental disorders and are improving treatment understanding.
research Different synaptic stimulation patterns influence the local androgenic and estrogenic neurosteroid availability triggering hippocampal synaptic plasticity in the male rat
The availability of certain hormones and specific stimulation patterns affect long-term synaptic changes in the male rat brain.
research Sexual dimorphism of growth plate prehypertrophic and hypertrophic chondrocytes in response to testosterone requires metabolism to dihydrotestosterone (DHT) by steroid 5‐alpha reductase type 1
Male cells need DHT to respond to testosterone, while female cells do not.
research A long-term follow-up study of men born with very low birth weight and their reproductive hormone profile
Men born very underweight had higher estrogen levels but normal reproduction compared to normal birth weight men.
research Cyclic Changes in the Metabolism of Estradiol by Rat Skin During the Hair Cycle**From the Departments of Dermatology and Biochemistry. University of Miami School of Medicine. Miami, Florida, 33136.
research A case report of a novel homozygote mutation causing severe Leydig cell hypoplasia: insights in the coexistence of nonsense mutation and polymorphism in the same LHCGR gene locus
A new genetic mutation causes severe Leydig cell hypoplasia, affecting sexual development.
research (192) Evaluating Effect of hCG and hCG+rFSH Therapy on Ejaculation Disorders in Middle-Aged Men: A Case Study
The therapies improved ejaculation disorders and sexual function in middle-aged men.
research Associations between genetically predicted sex and growth hormones and facial aging in the UK Biobank: a two−sample Mendelian randomization study
Regulating certain sex hormones may help delay facial aging.
research Sex Hormone-Binding Globulin as more than a Biomarker of Metabolic Diseases and Reproductive Disorders: What Physicians Should Know?
Low SHBG levels are linked to negative health outcomes and should be used in assessing and managing health conditions.
research Studies on neurosteroids XXIV. Determination of neuroactive androgens, androsterone and 5α‐androstane‐3α,17β‐diol, in rat brain and serum using liquid chromatography–tandem mass spectrometry
The methods accurately measured brain androgens, showing most 5α-androstane-3α,17β-diol comes from outside the brain, while androsterone is both transported and made in the brain.
research Urinary 5-ene-steroid excretion in non-classical congenital adrenal hyperplasia due to 3β-hydroxysteroid dehydrogenase deficiency (NC-3BHSD)
Some women with excess hair growth have a hormone condition that can't be diagnosed by blood or urine tests alone.
research Null Mutation of 5α-Reductase Type I Gene Alters Ethanol Consumption Patterns in a Sex-Dependent Manner
research Gonadal Function in Men with Cushing Syndrome
Cushing syndrome often causes low testosterone and sexual issues in men.
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 Dimorphic regulation of the MafB gene by sex steroids in hamsters (Mesocricetus auratus)
Sex steroids affect the MafB gene differently in male and female hamsters.
research Neo-synthesis of estrogenic or androgenic neurosteroids determine whether long-term potentiation or depression is induced in hippocampus of male rat
DHT is needed for long-term depression, while E2 is needed for full long-term potentiation in male rat brains.
research Gonadal Function in Men with Cushing Syndrome
Men with low testosterone or breast growth should be checked for Cushing syndrome.
research Recommendations of endocrine treatment for patients with gender dysphoria
The document concludes that hormone therapy is essential for treating gender dysphoria, with specific drugs and monitoring protocols recommended for safety and effectiveness.
research Isosexual Precocious Pseudopuberty Secondary to a Testosterone-Secreting Leydig Cell Testicular Tumour: True Isosexual Development Early After Surgery*
A boy's early puberty caused by a testicular tumor returned to normal after surgery.
research Society for Endocrinology guidelines for testosterone replacement therapy in male hypogonadism
Testosterone replacement is recommended for men with low testosterone levels and symptoms of hypogonadism.
research Hormonal Therapies for Individuals with Intersex Conditions
research Association between the serum estrone-to-estradiol ratio and parameters related to glucose metabolism and insulin resistance in women with polycystic ovary syndrome
Higher estrone-to-estradiol ratios are linked to worse glucose metabolism and insulin resistance in women with PCOS.
research 7472 Estrogen Monotherapy for Testosterone Suppression in Gender Diverse Patients
Estrogen alone may effectively suppress testosterone in some transfeminine individuals.
research Retinoic acid exerts sexually dimorphic effects on muscle energy metabolism and function
Retinoic acid affects male and female muscle energy use and function differently.
research Organizational Effects of Estrogens and Androgens on Estrogen and Androgen Receptor Expression in Pituitary and Adrenal Glands in Adult Male and Female Rats
Early hormones shape sex-specific differences in rat glands.
research Reproductive and Nonreproductive Actions of Testosterone
Testosterone is important for male sexual traits, reproduction, muscle and bone health, blood production, and metabolism, and works both directly and after being changed into other hormones.
research Studies on changes in the concentration of serum adrenal androgens in pubertal twins
Adrenal androgens are important for puberty and are influenced by genetics.
research 17-Oximino-5-androsten-3β-yl esters: synthesis, antiproliferative activity, acute toxicity, and effect on serum androgen level
Some synthesized compounds were more effective than Finasteride in reducing prostate cancer cell growth and androgen levels.
research A Perspective on the Evolving Landscape in Male Reproductive Medicine
Advancements in male reproductive medicine are ongoing, but more research and improved treatments are needed in several areas.
