Testicular Biopsies in Adolescent and Adult Andrological Patients: The EAA Clinical Guidelines

Andrology, EarlyView.
ABSTRACT Background Histological evaluation of testicular tissue is central to the assessment of infertile men, particularly those at an increased risk of testicular germ cell tumors (TGCT). Traditionally, testicular biopsies have been used primarily for diagnostic purposes, such as the detection of germ cell neoplasia in situ (GCNIS). With advances in

Sertoli–Leydig cell tumor of the ovary: A diagnostic dilemma

Gynecologic Oncology Reports, 2016
Background: Sertoli–Leydig cell tumors are rare sex-cord stromal tumors of the ovary that can present with a variety of histological elements, which may complicate diagnosis and treatment.

Adenosine—A Regulator of Human Testicular Peritubular Cells

Andrology, EarlyView.
ABSTRACT Background Extracellular purines, in particular ATP and adenosine, are regulators of physiological and pathophysiological processes throughout the human body. Roles in the human testis are emerging and include actions on peritubular cells, which form the wall of seminiferous tubules.

Current Approaches to Support Patients to Withdraw From Image and Performance Enhancing Drugs

Clinical Endocrinology, EarlyView.
ABSTRACT Image and performance‐enhancing drugs (IPEDs) include agents such as androgens, growth hormone, and erythropoietin, which are used to enhance appearance and physical performance. Androgens, also known as anabolic‐androgenic steroids (AAS), are the most used IPEDs worldwide.

Targeting m6A Modifications Regulating Ferroptosis Offers Novel Therapy in Diseases

Cell Proliferation, EarlyView.
m6A RNA modification regulates ferroptosis by balancing iron metabolism, lipid peroxidation, and antioxidant defenses. Dysregulated m6A signaling disrupts pro‐ and anti‐ferroptotic factors, leading to excess ROS, Fe3+ accumulation, and lipid peroxidation–driven cell death. Targeting m6A‐mediated ferroptotic regulation represents a promising therapeutic

Poorly Differentiated Ovarian Sertoli-Leydig Cell Tumor in a 16-Year-Old Single Woman: A Case Report and Literature Review

Case Reports in Obstetrics and Gynecology, 2013
Sertoli-Leydig cell tumor (SLCT) of ovary is an exceedingly unusual neoplasm that belongs to a group of sex cord-stromal tumors of ovary and accounts for less than 0.5% of all primary ovarian neoplasms.

Virilising ovarian tumors: a single-center experience

Endocrine Connections, 2018
Literature on virilising ovarian tumors (VOTs) is limited to case reports and series reporting single pathological type. We have analyzed the clinical, hormonal, radiological, histological, management and outcome data of VOT. This retrospective study was

Hypercortisolism: Causes, Consequences and Clinical Significance – A Review of Pathophysiology

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Hypercortisolism or Cushing syndrome is a heterogeneous clinical spectrum caused by chronic glucocorticoid excess, ranging from exogenous Cushing syndrome to rare endogenous aetiologies and the increasingly recognised entity of mild autonomous cortisol secretion (MACS). Physiological cortisol production is tightly regulated by the hypothalamic–
