Testicular biopsy in the study of male infertility: its current usefulness, histologic techniques, and prospects for the future

Human Pathology
H S Levin


Testicular biopsy has been widely used for the diagnosis of male infertility for more than three decades. During that time, with advances in cytogenetics, radioimmunoassay, and endocrinology, the role of testicular biopsy has changed. Testicular biopsy is still useful in the diagnosis of azoospermic and oligospermic males without stigmata of gonadotropic insufficiency or Klinefelter's syndrome. A classification and description is presented of pathologic changes in the testis as seen on testicular biopsy by light microscopy. The present rationale for testicular biopsy in infertility, the processing and staining of histologic material, and the role of testicular biopsy in infertility and infertility related situations, including cryptorchidism, malignant disease, and chemotherapy related changes, are discussed. Further understanding of testicular function and disease will depend upon the correlation of histologic and ultramicroscopic changes, immunohistologic localization of hormones, and epidemiologic and endocrinologic data.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Congenital Hyperinsulinism

Congenital hyperinsulinism is caused by genetic mutations resulting in excess insulin secretion from beta cells of the pancreas. Here is the latest research.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Epigenetic Memory

Epigenetic memory refers to the heritable genetic changes that are not explained by the DNA sequence. Find the latest research on epigenetic memory here.

Cell Atlas of the Human Eye

Constructing a cell atlas of the human eye will require transcriptomic and histologic analysis over the lifespan. This understanding will aid in the study of development and disease. Find the latest research pertaining to the Cell Atlas of the Human Eye here.

Femoral Neoplasms

Femoral Neoplasms are bone tumors that arise in the femur. Discover the latest research on femoral neoplasms here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
