The use of deidentified organ donor testes for research
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 ...

Abstract Background WFS1 spectrum disorder, also known as Wolfram syndrome (WS) is an ultra‐rare (<1:500,000; ORPHA: 3463) monogenic (OMIM #222300) progressive neuroendocrine and neurodegenerative disorder, characterised by early‐onset insulin‐dependent diabetes, optic atrophy, central diabetes insipidus and sensi‐neuronal deafness.

Pharmacogenetics of follicle‐stimulating hormone action in the male
Abstract Male factor infertility (MFI) is involved in half of the cases of couple infertility. The follicle‐stimulating hormone (FSH) therapy is considered efficient to improve semen parameters and pregnancy rate in patients with idiopathic MFI, following the lesson learned from hypogonadotropic hypogonadism.

The role of iron in normal and impaired testicular function
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 ...

Reversibility of sex changes in the plant kingdom: more important than we thought?
ABSTRACT Compared to animals, plants show a wide range of reproductive strategies with different degrees of sex separation (e.g. dioecy, monoecy, hermaphroditism). While sex expression was previously thought to be genetically determined and fixed in plants, accumulating evidence suggests that sex expression can change reversibly even within one ...
