AFM characterization of rabbit spermatozoa
, 2008 Atomic force microscopy (AFM) has been applied for determining the topological and structural features of rabbit spermatozoa. Fresh ejaculated spermatozoa were adsorbed passively onto a silicon slide or by motility from suspension onto a poly(L-lysine ...

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 ...

The effect of hyposmotic shock on motility and calcium signalling of human spermatozoa [PDF]
, 2011 Chloride (Cl\(^-\)) channels are thought to be implicated in volume regulation of human spermatozoa, a process vital for diverse cell functions. The Cl\(^-\) channel blockers DIDS, NPPB and niflumic acid were utilized to evaluate the influence of Cl\(^-\)

Andrology, EarlyView.Abstract Background Poor semen quality is a well‐known feature in patients with testicular germ cell tumours (GCTs) at the time of diagnosis but the underlying biological reasons are incompletely understood. Objectives This study aimed to identify GCT‐specific clinical factors that are involved with poor semen quality in GCT patients.

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 ...

The response of human spermatozoa to chemoattractants
, 2010 The effect of the chemoattractant bourgeonal on [Ca\(^{2+}\)]i and chemotaxis in human sperm was investigated. Burgeonal induced a dose-dependent, slowly-developing tonic elevation in [Ca\(^{2+}\)]i, The response was dependent on capacitation. In low-Ca\(

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.

Healthy Aging Men Do Not Suffer From Relevant Limitations of Their Reproductive Functions
Andrology, EarlyView.Abstract Background While metabolic disorders are well‐established contributors to testosterone decline and erectile dysfunction (ED), little is known about the natural progression of reproductive parameters in healthy aging men. Objectives This study aimed to evaluate longitudinal changes in reproductive parameters and sought to determine the ...
