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.

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.

Impacts of the use of chemiluminescent enzyme immunoassay-measured plasma aldosterone concentration in the diagnostic process of unilateral primary aldosteronism: a real-world multicenter study in Japan

Endocrine Journal
Unilateral primary aldosteronism (UPA) is characterized by a severe clinical phenotype and can be cured by adrenalectomy. Establishing accurate cutoff values that indicate the need for adrenal venous sampling (AVS) is crucial.

Basal body temperature as a biomarker of reproductive state in ewes: A multi‐method comparison

Australian Veterinary Journal, EarlyView.
This study quantified body temperature dynamics throughout reproductive stages in crossbred ewes based on complementary monitoring techniques. Five ewes from a semi‐extensive farming system were included in two sub‐trials: animals were first assessed in the prepubertal stage and, subsequently, an oestrous cycle was induced by intravaginal progesterone ...
