Trait coevolution and causal inference using generalized dynamic phylogenetic models

Methods in Ecology and Evolution, EarlyView.
Abstract Phylogenetic comparative methods are widely used to study trait coevolution across biological and cultural domains. The most common methods are phylogenetic generalized linear (mixed) models, phylogenetic path analysis, Pagel's ‘discrete’ method and Ornstein–Uhlenbeck models. While some frameworks like generalized linear mixed models are quite

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.

Semen quality in patients with testicular cancer is associated with age and with greatly elevated levels of beta human chorionic gonadotropin

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.

Multifactorial determinants of male genital measurements: Correlations of stretched penile length and anogenital distance with anthropometric parameters

Andrology, EarlyView.
Abstract Background The stretched penile length is recognized as the most reliable measure of true penile size, this fact is not widely acknowledged, and societal myths often associate penile length with other anthropometric measurements. While markers of prenatal androgen exposure, such as anogenital distance and the second‐to‐fourth digit ratio (2D ...

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 ...
