Iron and Other Metal Ions in Human Health and Disease
MedComm, Volume 7, Issue 10, October 2026.Iron, copper, zinc, and calcium orchestrate cellular function through distinct yet cooperative mechanisms: redox‐active iron and copper cycle between oxidation states to act as Fenton catalysts and electron carriers in oxidative phosphorylation (OXPHOS); redox‐inert zinc serves as a structural component of zinc‐finger proteins and a catalytic cofactor ...

Correlation of serum FSH and rate of testicular sperm retrieval in non-obstructive azoospermia
Indian Journal of Endocrinology and Metabolism, 2023 Background: Sperm retrieval from men with azoospermia has evolved in recent times, providing patient hope for fulfilling their dream of having their own genetic child through testicular sperm extraction followed by intracytoplasmic sperm injection (TESE ...

Testicular Biopsies in Adolescent and Adult Andrological Patients: The EAA Clinical Guidelines
Andrology, Volume 14, Issue 7, Page 1906-1928, October 2026.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

Focus Issue on Male Infertility
Advances in Urology, 2012 Male infertility problems can occur when sperms are limited in number or function. In this paper, we describe the clinical evaluation of male infertility. A detailed history, physical examination, and basic semen analysis are required.

A multiplex tissue resource for high‐resolution spatial protein profiling in the Human Protein Atlas
Protein Science, Volume 35, Issue 9, September 2026.Abstract Spatially resolved protein expression is essential for understanding tissue organization, cellular specialization, and protein function. The open‐access Human Protein Atlas database (www.proteinatlas.org) has generated an extensive antibody‐based tissue resource for a majority of the human protein‐coding genes using conventional ...
