Cut-off Value of Testosterone and FSH Level In Patient With Azoospermia [PDF]
, 2016 Follicle-stimulating hormone(FSH) and Testosterone are important for spermatogenesis. Increased serum FSH and decreased testosterone are related to abnormal spermatogenesis.

Andrology, EarlyView.ABSTRACT Background Testicular germ cell tumours (TGCT) are the most common malignancies among young men and represent a major threat to reproductive health. Both the disease itself and oncological treatments, particularly chemotherapy, can compromise spermatogenesis and semen quality.

Andrology, EarlyView.ABSTRACT Introduction Direct experimental investigation of Klinefelter syndrome (KS) in patients is limited because the syndrome manifests heterogeneously and affects multiple organ systems. Studying KS therefore requires a model that captures this complexity as accurately as possible while still permitting controlled experimental manipulation ...

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.

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 ...

Exosomas seminales y microRNAs: nueva fuente de biomarcadores de azoospermia [PDF]
, 2023 Aunque la azoospermia afecte a una significativa proporción de la población masculina, es innegable que los métodos de diagnóstico actuales aún presentan importantes limitaciones, caracterizadas por su carácter invasivo y la falta de especificidad.

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
