T Cell Microenvironmental Impacts and Therapeutic Opportunities: Application to Human Testicular Germ Cell Tumors

Andrology, EarlyView.
ABSTRACT Testicular germ cell tumors (TGCT) are the leading malignancy in adolescent and young adult males, yet the immunological and cellular mechanisms governing their tumor microenvironment (TME) remain poorly understood. Here, we present a comprehensive review of TGCT pathobiology with a focus on the immune landscape, particularly the role of tumor‐

Pure Sertoli cell tumor of the ovary: A case report

Clinical Case Reports, 2022
Pure Sertoli cell tumors are an uncommon variant of rare ovarian Sertoli‐Leydig cell tumors. Due to nonspecific clinical and imaging features, diagnosis is often made after histopathological examination. The prognosis is excellent as most are detected in

Peroxiredoxin 4 Involved in Spermatogenesis by Affecting Oxidative Stress and Ferroptosis

Andrology, EarlyView.
ABSTRACT Background The main functions of testes are sperm production and androgen secretion in testicular befitting microenvironment. Excessive level of the reactive oxygen species (ROS) from metabolism and cellular events can lead to oxidative stress (OS) and ferroptosis, which injure the functions of mitochondria and endoplasmic reticulum (ER) of ...

Boosting Male Fertility: The Impact of Gonadotropin Therapy on Hypogonadotropic Hypogonadism—A Systematic Review and Meta‐Analysis

Andrology, EarlyView.
ABSTRACT Background Male hypogonadotropic hypogonadism typically presents with azoospermia and is one of the few causes of infertility amenable to a medical intervention. Gonadotropin therapy offers a chance to restore spermatogenesis and fertility in these individuals.

Testicular Leydig Cell Tumor with Metachronous Lesions: Outcomes after Metastasis Resection and Cryoablation

Case Reports in Urology, 2015
Leydig cell tumors represent 3% of testicular masses and usually occur in prepubertal boys and men between 30 and 60 years of age. Leydig cell tumors are benign in children but can be malignant in 10% of adults.

Assessing a Model for a Complex Systemic Disorder—The Value of Male Mice With a Supernumerary X Chromosome for Klinefelter Syndrome Research

Andrology, EarlyView.
ABSTRACT Introduction Direct experimental investigation of Klinefelter syndrome (KS) in patients is limited because the syndrome manifests heterogeneously and affects multiple organ systems. Studying KS therefore requires a model that captures this complexity as accurately as possible while still permitting controlled experimental manipulation ...

Diacerein Disrupts Testicular Homeostasis: The Essential Role of Basal Cytokines in Maintaining Sertoli Cell Integrity and the Immune Microenvironment

Andrology, EarlyView.
ABSTRACT Background Pro‐inflammatory cytokines, TNF and IL‐1B, are essential for testicular homeostasis. Diacerein, an anti‐inflammatory drug, inhibits these cytokines, impairing M2 macrophages and Leydig cells (LCs). However, its impact on Sertoli cells (SCs) and M1 (CD68) macrophages remains unknown.

Neoplastic Risk in Patients With Klinefelter Syndrome

Andrology, EarlyView.
ABSTRACT Background Besides gonadal involvement (hypogonadism, male factor infertility, and testicular hypotrophy), patients with Klinefelter syndrome (KS) may suffer from several extra‐gonadic complications, including neoplastic events. Objective The aim of this review is to summarize all major clinical evidence dealing with the association between KS

Gynecomastia and Leydig cell tumors in the adult

Cleveland Clinic Journal of Medicine, 1984
Two men with gynecomastia were evaluated at The Cleveland Clinic Foundation. Both were subsequently found to have a Leydig cell tumor of the left testis. One patient had previously undergone a testicular biopsy examination because of presumed infertility; the other had undergone the same type of examination due to a suspicious enlargement of the ...
