    Steroid resistance syndrome (mineralocorticoids, glucocorticoids, estrogens, androgens) is a rare clinical disorder, androgen insensitivity syndrome being the most commonly described. Resistance syndromes are characterized by elevated steroid hormone levels, secondary to an impaired signal transduction and a lack of negative feedback, without any specific clinical signs of steroid excess. In most cases, steroid hormone resistance is generally caused by steroid receptor mutations. Read More

    MECHANISMS IN ENDOCRINOLOGY: The sexually dimorphic role of androgens in human metabolic disease.
    Eur J Endocrinol 2017 May 31. Epub 2017 May 31.
    M O'Reilly, Institute of Metabolism and Systems Research, University of Birmingham, Birmingham, United Kingdom of Great Britain and Northern Ireland
    Female androgen excess and male androgen deficiency manifest with an overlapping adverse metabolic phenotype, including abdominal obesity, insulin resistance, type 2 diabetes mellitus, non-alcoholic fatty liver disease and an increased risk of cardiovascular disease. Here we review the impact of androgens on metabolic target tissues in an attempt to unravel the complex mechanistic links with metabolic dysfunction; we also evaluate clinical studies examining the associations between metabolic disease and disorders of androgen metabolism in men and women. We conceptualise that an equilibrium between androgen effects on adipose tissue and skeletal muscle underpins the metabolic phenotype observed in female androgen excess and male androgen deficiency.

    Front Neuroendocrinol 2017 May 25. Epub 2017 May 25.
    Centre for Neuroendocrinology and Department of Physiology, Biomedical Sciences, University of Otago, Dunedin 9054, New Zealand. Electronic address:
    Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder and the leading cause of anovulatory infertility. Characterised by hyperandrogenism, menstrual dysfunction and polycystic ovaries, PCOS is a broad-spectrum disorder unlikely to stem from a single common origin. Although commonly considered an ovarian disease, the brain is now a prime suspect in both the ontogeny and pathology of PCOS. Read More

    The effects of chronic testosterone administration on body weight, food intake, and adipose tissue are changed by estrogen treatment in female rats.
    Horm Behav 2017 May 17;93:53-61. Epub 2017 May 17.
    Department of Obstetrics and Gynecology, Institute of Biomedical Sciences, Tokushima University Graduate School, 3-18-15 Kuramoto-Cho, Tokushima 770-8503, Japan.
    In females, estrogens play pivotal roles in preventing excess body weight (BW) gain. On the other hand, the roles of androgens in female BW, appetite, and energy metabolism have not been fully examined. We hypothesized that androgens' effects on food intake (FI) and BW regulation change according to the estrogens' levels. Read More

    Insulin sensitizers in adolescents with polycystic ovary syndrome.
    Minerva Pediatr 2017 May 11. Epub 2017 May 11.
    Division of Endocrinology, Department of Internal Medicine, Virginia Commonwealth University, Richmond, VA, USA.
    Polycystic ovary syndrome (PCOS) is the most common disorder of androgen excess in women of reproductive age. The diagnosis of PCOS can be more challenging in adolescents than in adult women given significant overlap between normal puberty and the signs of PCOS, including acne, menstrual irregularity, and polycystic ovarian morphology. Optimal treatments for adult women with PCOS vary depending on patient risk factors and reproductive goals, but mainly include hormonal contraception and insulin sensitizers. Read More

    Department of Biostatistics, Yale University School of Public Health, New Haven, CT.
    Background: While female sexual dysfunction is a frequent occurrence, characteristics in infertile women are not well delineated. Furthermore, the impact of infertility etiology on the characteristics in women with differing androgen levels observed in women with polycystic ovary syndrome and unexplained infertility has not been assessed.

    Objective: The objective of the study was to determine the characteristics of sexual dysfunction in women with polycystic ovary syndrome and unexplained infertility. Read More

    Confounder factors masking a Leydig-cell ovarian tumor in a post-menopausal woman treated for androgen-positive receptor breast cancer.
    Gynecol Endocrinol 2017 Apr 26:1-5. Epub 2017 Apr 26.
    a Endocrinology Division.
    Post-menopause hyperandrogenism is a condition that needs careful evaluation. Aromatase inhibitors (AI), which are important in the management of positive estrogen breast cancer, and chronic kidney disease (CKD) can puzzle the evaluation of this condition. A postmenopause female with type-2 diabetes and advanced CKD was attended due to progressive virilization, which has started after the introduction of an AI for breast cancer 5 years earlier.

    A Case Report of Cushing's Disease Presenting as Hair Loss.
    Case Rep Dermatol 2017 Jan-Apr;9(1):45-50. Epub 2017 Feb 21.
    Department of Dermatology, Roger Williams Medical Center, Providence, RI, USA.
    Cushing's syndrome is a rare endocrine disorder that comprises a large group of signs and symptoms resulting from chronic exposure to excess corticosteroids. Most cases of Cushing's syndrome are due to increased adrenocorticotropic hormone production from a pituitary adenoma, which is referred to as Cushing's disease. Most of the signs and symptoms are nonspecific and common in the general population, making a diagnosis often challenging. Read More

    Maternal hirsutism and autism spectrum disorders in offspring.
    Autism Res 2017 Apr 6. Epub 2017 Apr 6.
    Centre for Epidemiology and Community Medicine, Stockholm County Council, Stockholm, 17129, Sweden.
    Because animal and human studies indicate that androgen exposure can influence neurodevelopment, it has been hypothesized that prenatal exposure to excess androgens may predispose to disorders with male-skewed ratio such as autism spectrum disorders (ASD). Therefore, maternal conditions characterized by hyperandrogenism such as polycystic ovary syndrome (PCOS) or hirsutism may be relevant to child ASD. We previously found in a large Swedish case-control study of 23,748 ASD cases and 208,796 matched controls that PCOS in mothers is associated with increased offspring risk of ASD. Read More

    Chinese Herbal Medicine for the Optimal Management of Polycystic Ovary Syndrome.
    Am J Chin Med 2017 30;45(3):405-422. Epub 2017 Mar 30.
    * School of Life Sciences, University of Technology Sydney, NSW 2007, Australia.
    Polycystic ovary syndrome (PCOS) is a complex heterogeneous disorder characterized by androgen excess and ovulatory dysfunction; it is now known to be closely linked to metabolic syndrome. Recent research suggests that insulin resistance plays an important role in the pathogenesis of PCOS which may lead to the excessive production of androgens by ovarian theca cells. Currently there is no single drug that can treat both the reproductive and metabolic complications of the disorder. Read More

    J Clin Endocrinol Metab 2017 Mar;102(3):1044-1050
    Birmingham Children's Hospital, Birmingham B15 2TT, United Kingdom; and.
    Context: It is well established that boys are heavier than girls at birth. Although the cause of birth weight (BW) difference is unknown, it has been proposed that it could be generated from prenatal androgen action.

    Objective: The aim of the current study was to determine the BW of children with disorders of sex development (DSD) of different etiologies and to evaluate the effects of androgen action on BW. Read More

    Modulation of steroidogenesis by vitamin D3 in granulosa cells of the mouse model of polycystic ovarian syndrome.
    Syst Biol Reprod Med 2017 Jun 27;63(3):150-161. Epub 2017 Mar 27.
    a Department of Anatomy, School of medicine , Tehran University of Medical Sciences , Tehran , Iran.
    Polycystic ovarian syndrome (PCOS) is the most common endocrine disorder of women of reproductive age characterized by polycystic ovarian morphology, anovulation or oligomenorrhea, and hyperandrogenism. It is shown that disruption in the steroidogenesis pathway caused by excess androgen in PCOS is a critical element of abnormal folliculogenesis and failure in dominant follicle selection. Vitamin D plays an important role in the regulation of ovulatory dysfunction and can influence genes involved in steroidogenesis in granulosa cells. Read More

    Effects of Chronic ACTH Excess on Human Adrenal Cortex.
    Front Endocrinol (Lausanne) 2017 8;8:43. Epub 2017 Mar 8.
    Service des Maladies Endocriniennes et Métaboliques, Centre de Référence des Maladies Rares de la Surrénale, Faculté de Médecine Paris Descartes, Université Paris 5, Hôpital Cochin , Paris , France.
    Chronic ACTH excess leads to chronic cortisol excess, without escape phenomenon, resulting in Cushing's syndrome. Excess adrenal androgens also occur: in females, they will overcompensate the gonadotrophic loss, inducing high testosterone; in males, they will not compensate it, inducing low testosterone. Chronic ACTH excess leads to chronic adrenal mineralocorticoid excess and low aldosterone levels: after an acute rise, aldosterone plasma levels resume low values after a few days when ACTH is prolonged.

    Androgen Stimulates Growth of Mouse Preantral Follicles In Vitro: Interaction With Follicle-Stimulating Hormone and With Growth Factors of the TGFβ Superfamily.
    Endocrinology 2017 Apr;158(4):920-935
    Institute of Reproductive and Developmental Biology, Imperial College London, Hammersmith Hospital, London W12 0NN, United Kingdom.
    Androgens are essential for the normal function of mature antral follicles but also have a role in the early stages of follicle development. Polycystic ovary syndrome (PCOS), the most common cause of anovulatory infertility, is characterized by androgen excess and aberrant follicle development that includes accelerated early follicle growth. We have examined the effects of testosterone and dihydrotestosterone (DHT) on development of isolated mouse preantral follicles in culture with the specific aim of investigating interaction with follicle-stimulating hormone (FSH), the steroidogenic pathway, and growth factors of the TGFβ superfamily that are known to have a role in early follicle development.

    Neuroendocrine androgen action is a key extraovarian mediator in the development of polycystic ovary syndrome.
    Proc Natl Acad Sci U S A 2017 Apr 20;114(16):E3334-E3343. Epub 2017 Mar 20.
    Andrology Laboratory, ANZAC Research Institute, University of Sydney, Sydney, NSW 2139, Australia;
    Polycystic ovary syndrome (PCOS) is a complex hormonal disorder characterized by reproductive, endocrine, and metabolic abnormalities. As the origins of PCOS remain unknown, mechanism-based treatments are not feasible and current management relies on treatment of symptoms. Hyperandrogenism is the most consistent PCOS characteristic; however, it is unclear whether androgen excess, which is treatable, is a cause or a consequence of PCOS. Read More

    Developmental Programming: Gestational Exposure to Excess Testosterone Alters Expression of Ovarian Matrix Metalloproteases and Their Target Proteins
    Reprod Sci 2017 01 1:1933719117697127. Epub 2017 Jan 1.
    1 Department of Pediatrics, University of Michigan, Ann Arbor, MI, USA.
    Prenatal testosterone (T)-treated sheep, similar to women with polycystic ovary syndrome (PCOS), manifests reproductive defects that include multifollicular ovarian phenotype. Women with PCOS manifest increased ovarian matrix metalloproteinases (MMPs) activity. We tested the hypothesis that gestational T excess in sheep would alter ovarian expression of MMPs, tissue inhibitors of MMP (TIMP) and their target proteins laminin B (LAMB), collagen, tumor necrosis factor alpha (TNF), and connexin 43 (GJA1) consistent with increased MMP activity and that these changes are developmentally regulated.

    Testosterone Levels in Pre-Menopausal Women are Associated With Nonalcoholic Fatty Liver Disease in Midlife.
    Am J Gastroenterol 2017 May 14;112(5):755-762. Epub 2017 Mar 14.
    Division of Gastroenterology and Hepatology, University of California, San Francisco, California, USA.
    Objectives: Young women with hyperandrogenism have high risk of metabolic co-morbidities, including increased risk of nonalcoholic fatty liver disease (NAFLD). Whether testosterone (the predominant androgen) is associated with NAFLD independent of metabolic co-factors is unclear. Additionally, whether testosterone confers increased risk of NAFLD in women without hyperandrogenism is unknown. Read More

    Alteration in follistatin gene expression detected in prenatally androgenized rats.
    Gynecol Endocrinol 2017 Jun 26;33(6):433-437. Epub 2017 Feb 26.
    a Cellular and Molecular Endocrine Research Center, Research Institute for Endocrine Sciences (RIES), Shahid Beheshti University of Medical Sciences , Tehran , Iran.
    Impaired ovarian follicle development, the hallmark of polycystic ovarian syndrome (PCOS), is believed to be due to the changes in expression of related genes such as follistatin (FST). Expression of FST gene and methylation level of its promoter in theca cells from adult female rats, prenatally exposed to androgen excess, during different phases of the estrus cycle was determined and compared with controls. Eight pregnant Wistar rats (experimental group) were treated by subcutaneous injection of 5 mg free testosterone on day 20 of pregnancy, while controls (n = 8) received 500 ml solvent. Read More

    Clinical significance of 11-oxygenated androgens.
    Curr Opin Endocrinol Diabetes Obes 2017 Jun;24(3):252-259
    aDivision of Metabolism, Endocrinology and Diabetes bDepartment of Pharmacology, University of Michigan, Ann Arbor, Michigan, USA.
    Purpose Of Review: The adrenal gland is considered a source of weak androgens, such as dehydroepiandrosterone, dehydroepiandrosterone sulfate, and androstenedione. Emerging evidence proposes a set of 11-oxygenated 19-carbon (11oxC19) adrenal-derived steroids as clinically important androgens. Such steroids include 11β-hydroxyandrostenedione, 11-ketoandrostenedione, 11β-hydroxytestosterone, and 11-ketotestosterone. Read More

    High serum progesterone associated with infertility in a woman with nonclassic congenital adrenal hyperplasia.
    J Obstet Gynaecol Res 2017 Feb 11. Epub 2017 Feb 11.
    Department of Reproductive Medicine, Graduate School of Medicine, Chiba University, Chiba, Japan.
    Nonclassic congenital adrenal hyperplasia (NCAH) is an autosomal-recessive disorder caused by 21-hydroxylase deficiency and manifests as hirsutism and oligomenorrhea due to excess adrenal androgen and progesterone. We report a case of a woman with NCAH who showed continuous high serum progesterone levels in the follicular phase associated with impaired folliculogenesis. NCAH was diagnosed based on high 17-hydroxyprogesterone levels after rapid adrenocorticotropic hormone loading, and three heterozygous missense mutations in CYP21A2, encoding 21-hydroxylase, were identified.

    Sex differences in the effects of androgens acting in the central nervous system on metabolism.
    Dialogues Clin Neurosci 2016 Dec;18(4):415-424
    Department of Medicine, Section of Endocrinology and Metabolism, Tulane University Health Sciences Center, School of Medicine, New Orleans, Louisiana, USA.
    One of the most sexually dimorphic aspects of metabolic regulation is the bidirectional modulation of glucose and energy homeostasis by testosterone in males and females. Testosterone deficiency predisposes men to metabolic dysfunction, with excess adiposity, insulin resistance, and type 2 diabetes, whereas androgen excess predisposes women to insulin resistance, adiposity, and type 2 diabetes. This review discusses how testosterone acts in the central nervous system, and especially the hypothalamus, to promote metabolic homeostasis or dysfunction in a sexually dimorphic manner. Read More

    Objective: Acne is not solely a cosmetic problem. The clinical importance of acne in the estimation of androgen excess disorders is controversial. Recently, the Amsterdam ESHRE/ASRM-sponsored third PCOS Consensus Workshop Group suggested that acne is not commonly associated with hyperandrogenemia and therefore should not be regarded as evidence of hyperandrogenemia.

    Adrenocortical neoplasms in adulthood and childhood: distinct presentation. Review of the clinical, pathological and imaging characteristics.
    J Pediatr Endocrinol Metab 2017 Mar;30(3):253-276
    Adrenocortical tumors (ACT) in adulthood and childhood vary in clinical, histopathological, molecular, prognostic, and imaging aspects. ACT are relatively common in adults, as adenomas are often found incidentally on imaging. ACT are rare in children, though they have a significantly higher prevalence in the south and southeast regions of Brazil. Read More

    Cryptotanshinone Regulates Androgen Synthesis through the ERK/c-Fos/CYP17 Pathway in Porcine Granulosa Cells.

    The aim of the study is to investigate the molecular mechanism behind androgen reduction in porcine granulosa cells (pGCs) with Salvia miltiorrhiza Bunge extract cryptotanshinone. PGCs were isolated from porcine ovaries and identified. Androgen excess model of the pGCs was induced with the MAPK inhibitor PD98059 and then treated with cryptotanshinone. Read More

    Oral Spironolactone for Acne Vulgaris in Adult Females: A Hybrid Systematic Review.
    Am J Clin Dermatol 2017 Apr;18(2):169-191
    Department of Dermatology, Leiden University Medical Center, Leiden, The Netherlands.
    Background: The management of acne in adult females is problematic, with many having a history of treatment failure and some having a predisposition to androgen excess. Alternatives to oral antibiotics and combined oral contraceptives (COCs) are required.

    Objective: Our aim was to conduct a hybrid systematic review of the evidence for benefits and potential harms of oral spironolactone in the management of acne in adult females. Read More

    Selective deletion of Pten in theca-interstitial cells leads to androgen excess and ovarian dysfunction in mice.

    Theca cell-selective Pten mutation (tPtenMT) in mice resulted in increases in PDK1 and Akt phosphorylation, indicating an over-activation of PI3K signaling in the ovaries. These mice displayed elevated androgen levels, ovary enlargement, antral follicle accumulation, early fertility loss and increased expression of Lhcgr and genes that are crucial to androgenesis. These abnormalities were partially reversed by treatments of PI3K or Akt inhibitor. Read More
