Combined anterior pituitary function test using CRH, GRH, LH-RH, TRH and vasopressin in patients with non-functioning pituitary tumors.

We examined 8 normal subjects and 16 patients with non-functioning pituitary tumors with a combined anterior pituitary test to evaluate the clinical usefulness of the test.

Sex‐Specific Involvement of Gut Microbiota in Behavioral and Endocrine Responses to Chronic Predator Odor in Brandt's Voles

Integrative Zoology, EarlyView.
18 days of predator odor exposure altered gut microbiota, increased anxiety‐like behaviors, and elevated hypothalamic–pituitary–adrenal axis activity in Brandt's voles, with males showing behavioral habituation and females remaining sensitive. Cecal microbiota transplantation experiments confirmed that only female recipients of microbiota from predator‐

Can Food Acquisition Priority Alter Emotion, Physiological Responses, and Social Rank in Fish?

Integrative Zoology, EarlyView.
We tested whether a cichlid fish perceives inequitable food distribution by manipulating feeding order. Priority‐fed individuals consumed more, had higher condition factors, and exhibited lower whole‐body cortisol than delayed‐fed fish, while personality, metabolism, dopamine, and social rank did not differ.

From allostasis to addiction: Cortisol dysregulation, daily stress and relations with 9‐year alcohol and substance use disorder severity in community adults

Addiction, EarlyView.
Abstract Background and aims Diurnal cortisol dysregulation and daily stressor severity may jointly forecast long‐term alcohol use disorder (AUD) and substance use disorder (SUD) severity, yet most evidence is cross‐sectional and relies on single cortisol indices.

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.

Association Between FTO rs1558902 Polymorphism, Age‐Related Hypogonadism, and Central Obesity in Japanese Men

Andrology, EarlyView.
ABSTRACT Background Obesity and low testosterone levels are closely interconnected, with the FTO gene being the most robust genetic determinant of body mass index (BMI). However, whether this primary genetic driver of obesity directly influences the hypothalamic‐pituitary‐testicular (HPT) axis remains unclear.

Sleep Disorders in Klinefelter Syndrome and Other Sex Chromosome Aneuploidies: A Narrative Review

Andrology, EarlyView.
ABSTRACT Background Sex chromosome aneuploidies (SCAs) are among the most frequent types of chromosomal aneuploidies and include Klinefelter syndrome (47,XXY and higher‐grade variants), 47,XYY syndrome, Turner syndrome (45,X), and trisomy X (47,XXX).

Machine Learning‐Based Prediction of Sperm Retrieval Outcomes in Patients With Klinefelter Syndrome: A Multicenter Study With External Validation

Andrology, EarlyView.
ABSTRACT Background The Klinefelter syndrome is a common genetic cause of male infertility, and testicular sperm extraction (TESE) enables sperm retrieval in a subset of affected patients. However, predicting TESE success remains challenging due to the heterogeneous clinical and endocrinological presentation of the Klinefelter syndrome.

The Bidirectional Association Between MASLD and Male Hypogonadism: An Updated Meta‐Analysis

Andrology, EarlyView.
ABSTRACT Background Metabolic dysfunction‐associated steatotic liver disease (MASLD) and male hypogonadism are increasingly prevalent, metabolically interrelated conditions. Testosterone (T) deficiency has been implicated in hepatic lipid dysregulation, insulin resistance, and visceral adiposity, whereas MASLD may impair the hypothalamic–pituitary ...
