Testicular histopathology and its association with germ cell numbers, serum concentrations of reproductive hormones, and semen quality

Andrology, EarlyView.
Abstract Background It is well‐established that spermatogenesis, semen quality, and reproductive hormones are interlinked. It is, however, less well‐described how various specific testicular histopathologies are linked to reproductive hormones and semen quality.

The use of deidentified organ donor testes for research

Andrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

Effect of Propolis on Spermatogenic Cells Number and Diameter of Seminiferous Tubules in Male Mice (Mus musculus) [PDF]

, 2017
The present research aimed to determine the effect of propolis in spermatogenic cells number and seminiferous tubules diameter. Group P0 served as control group, P1 (1,6 mg/0,5ml/day), P2 (3,2 mg/0,5 ml/day), P3 (6,4 mg/0,5 ml/day), and P4 (12,8 mg/0,5 ...

The role of iron in normal and impaired testicular function

Andrology, EarlyView.
Abstract Iron plays a critical role in testicular physiology, impacting spermatogenesis, testosterone production, and overall testicular function. Iron homeostasis is maintained through systemic and cellular regulatory mechanisms, including hepcidin‐mediated systemic iron control and the iron‐responsive element/iron regulatory protein (IRE/IRP) system ...

CRISPR/Cas9‐mediated Genome‐editing Reveals 10 Testis‐enriched Genes and One Non‐testis‐enriched Gene are Dispensable for Male Fecundity in Mice

Andrology, EarlyView.
ABSTRACT Background More than 1000 genes have been identified as predominantly expressed in the human testis. Advances in gene editing technologies have enabled the rapid and efficient generation of genetically engineered mice. This approach facilitates the screening of genes essential for spermatogenesis by analyzing knockout mouse models.

Comprehensive Quantification of Oligoasthenozoospermia Induced by Obesity, Reproductive Toxicants, and Their Combination in Rat Models

Andrology, EarlyView.
ABSTRACT Background Oligoasthenozoospermia is a leading cause of male infertility and has been increasingly associated with the global surge in obesity and exposure to reproductive toxicants. Despite extensive research on each factor individually, their combined pathological effects remain poorly understood.

Effects of short-term administration of quinine on the seminiferous tubules of Sprague-Dawley Rats [PDF]

, 2004
Quinine (QU) is the principal alkaloid derived from the bark of the Cinchona tree and has been used worldwide in the suppression and treatment of malaria for more than 350 years. Though other anti-malaria drugs have superseded QU, however, as a result of
