Limited Clinical Impact of Androgen Receptor Repeat Length (CAG and GGC) in Klinefelter Syndrome: A Multivariable Analysis

Andrology, EarlyView.
ABSTRACT Background Klinefelter syndrome (KS) is characterized by marked phenotypic heterogeneity that might be influenced by genetic modifiers, including androgen receptor (AR) repeat length (CAGn and GGCn). The clinical relevance of these repeat lengths in patients with KS before testosterone replacement therapy (TRT) remains unclear.

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.

Impact of FSHB and FSHR Genes Polymorphisms on Hormonal Profile and Sperm Retrieval Outcome in Men With Klinefelter Syndrome: A Clinical–Genetic Predictive Study

Andrology, EarlyView.
ABSTRACT Background Genetic variability within the follicle‐stimulating hormone (FSH)‐related genes might contribute to phenotypic heterogeneity in patients with Klinefelter syndrome (KS), yet its clinical impact on sperm retrieval remains unclear. Objectives To investigate the association between FSHB c.211 G > T and FSHR polymorphisms (c.2039 A > G ...

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).

"Male menopause" : the birth of a new illness? [PDF]

, 2006
The existence of male menopause is uncertain (e.g. Snyder 2004; Rhoden & Morgenthaler 2004) and also the effects of HT have not yet been clarified as being reliably safe.

Loss‐of‐Function Variants in CCDC189 Cause Human Oligoasthenoteratozoospermia by Disrupting Sperm Flagellar and Acrosomal Architecture

Andrology, EarlyView.
ABSTRACT Background Oligoasthenoteratozoospermia (OAT), characterized by reduced sperm count, impaired motility, and abnormal morphology, is a major cause of male infertility with substantial genetic heterogeneity. However, the underlying genetic etiology remains unresolved in a large proportion of affected individuals.

Neoplastic Risk in Patients With Klinefelter Syndrome

Andrology, EarlyView.
ABSTRACT Background Besides gonadal involvement (hypogonadism, male factor infertility, and testicular hypotrophy), patients with Klinefelter syndrome (KS) may suffer from several extra‐gonadic complications, including neoplastic events. Objective The aim of this review is to summarize all major clinical evidence dealing with the association between KS

A Case of Male Osteoporosis: A 37-Year-Old Man with Multiple Vertebral Compression Fractures

Case Reports in Endocrinology, 2017
While the contributing role of testosterone to bone health is rather modest compared to other factors such as estradiol levels, male hypogonadism is associated with low bone mass and fragility fractures.

Feminizing Therapy in People With Klinefelter Syndrome and Gender Incongruence: Considerations for Treatment Without Testosterone Blockers

Andrology, EarlyView.
ABSTRACT Background Klinefelter syndrome (KS; 47, XXY) usually involves male sex development and gender identity. Small studies suggest gender incongruence may be more common in KS, but feminizing gender‑affirming hormone therapy in this group has been scarcely reported.
