Modified cytoskeletal and extracellular matrix composition in the canine testis after long‐acting gonadotropin‐releasing hormone agonist deslorelin treatment

open access: yesAndrology, EarlyView.
Abstract Background Long‐acting gonadotropin‐releasing hormone (GnRH) agonists are commonly used for fertility control in male dogs. Their effect on testicular histomorphology has not been clarified. Objectives To elucidate the mechanisms underlying androgen withdrawal in response to long‐acting GnRH agonist deslorelin 4.7 mg treatment on testicular ...

Maternal, childhood and adolescent influences on Leydig cell functional capacity and circulating INSL3 concentration in young adults: Importance of childhood infections and body mass index

open access: yesAndrology, EarlyView.
Abstract Background The constitutive Leydig cell hormone insulin‐like peptide 3 (INSL3) is considered a good estimate of the adult Leydig cell functional capacity and appears to remain relatively consistent throughout adult male life, only gradually declining into old age.

The aporetic dialogs of Modena on gender differences: Is it all about testosterone? Episode III: Mathematics

open access: yesAndrology, EarlyView.
Abstract This report is the transcript of what was discussed in a convention at the Endocrinology Unit in Modena, Italy, in the form of the aporetic dialogs of ancient Greece. It is the third episode of a series of four discussions on the differences between males and females, with a multidisciplinary approach. In this work, the role of testosterone in

Development of a nomogram for sperm retrieval at microTESE for idiopathic non‐obstructive azoospermia in a multi‐center cohort study

open access: yesAndrology, EarlyView.
Abstract Background Non‐obstructive azoospermia (NOA) affects approximately 10% of infertile men and represents a major challenge in assisted reproductive technology (ART). A model that includes histological variants could be helpful in predicting sperm retrieval rate (SRR) after microdissection testicular sperm extraction (mTESE) in patients affected ...

Effects of neonatal hypothyroidism on testicular development and undifferentiated spermatogonia in prepubertal rats

open access: yesAndrology, EarlyView.
Abstract Background Thyroid hormones play a key role in testicular development, particularly in the regulation of Sertoli cell proliferation and differentiation. While congenital hypothyroidism is common and treatable, the effects of thyroid hormone insufficiency on early testicular development during the neonatal period remain unclear. Objectives This

Lycium barbarum polysaccharides enhance testicular spermatogenesis in d‐galactose‐induced aging rats via calcium signaling

open access: yesAndrology, EarlyView.
Abstract Background Lycium barbarum polysaccharide (LBP) has long been recognized as having a wide range of beneficial properties for improving proliferation. However, the protective effects and specific mechanisms of d‐galactose‐induced testicular dysfunction in reproductively senescent rats are not fully understood.

Predicted Adult Height Remained Normal in Children With Premature Adrenarche Despite Advanced Bone Age

open access: yesActa Paediatrica, EarlyView.
ABSTRACT Aim Aetiological factors affecting the phenotype of adrenarche are largely unknown. This study investigated the phenotypic variability of premature adrenarche. Methods In this cross‐sectional retrospective registry study, data on 91 mainly Caucasian children diagnosed with premature adrenarche were retrieved from patient records.
