Gonadal Development–Related Genes and a Male‐Specific Genetic Marker Identified in the Endangered Sichuan Taimen (Hucho bleekeri)

open access: yesIntegrative Zoology, EarlyView.
Integrated transcriptomic and proteomic analyses were used to validate gonadal development–related genes and to identify a sex‐specific molecular marker in Hucho bleekeri. ABSTRACT Sex determination and differentiation represent fundamental topics in reproductive biology. Sichuan taimen (Hucho bleekeri), a first‐class national protected fish species in

Exercise ameliorates stanozolol and cannabis co-abuse testicular damage in rats evidenced by biochemical and histological regulation of SIRT1 and STS

open access: yesScientific Reports
Polydrug use among teenagers is widespread and emergent either among athletes or non-athletes. It is reported that stanzolol (Stanz) is commonly abused with cannabis (Cann), this combination probably affects the testicular functions negatively.

International Guideline on the Diagnosis and Management of Pediatric Patients With Hereditary Angioedema

open access: yesAllergy, EarlyView.
ABSTRACT Hereditary angioedema (HAE) with C1 inhibitor deficiency is a rare disease characterized by unpredictable episodes of tissue swelling (angioedema), which, in most cases, occur first under the age of 18 years, and entail a significant burden of disease not only for the patients but also for their families.

Anti-Müllerian hormone, testicular descent and cryptorchidism

open access: yesFrontiers in Endocrinology
Anti-Müllerian hormone (AMH) is a Sertoli cell-secreted glycoprotein involved in male fetal sex differentiation: it provokes the regression of Müllerian ducts, which otherwise give rise to the Fallopian tubes, the uterus and the upper part of the vagina. In the first trimester of fetal life, AMH is expressed independently of gonadotropins, whereas from

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

open access: yesAndrology, 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

open access: yesAndrology, 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 ...

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

open access: yesAndrology, 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

open access: yesAndrology, 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

open access: yesAndrology, 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 hypothalamic-pituitary-adrenal axis in critical illness [PDF]

open access: yes, 1993
Plasma ACTH and cortisol concentrations are frequently elevated in patients in intensive care units (ICU). To examine the functional integrity of the hypothalamic-pituitary-adrenal axis during critical illness, we evaluated prospectively 53 ICU patients ...
