Boosting Male Fertility: The Impact of Gonadotropin Therapy on Hypogonadotropic Hypogonadism—A Systematic Review and Meta‐Analysis

Andrology, EarlyView.
ABSTRACT Background Male hypogonadotropic hypogonadism typically presents with azoospermia and is one of the few causes of infertility amenable to a medical intervention. Gonadotropin therapy offers a chance to restore spermatogenesis and fertility in these individuals.

Paternal use of metformin and risk of major congenital malformations: A meta-analysis of 4 studies. [PDF]

Br J Clin Pharmacol
Abstract Metformin is the first‐line drug for the treatment of Type 2 diabetes. In 2022, a Danish registry‐based study reported a 40% increased risk of major congenital malformations following paternal exposure during spermatogenesis. This raised widespread concern about the use of metformin in males of reproductive age.

Cyclic Treatment With WIN 18,446, a Potential Male Contraceptive, is as Effective as Continuous Treatment for Suppression of Spermatogenesis in Mice

Andrology, EarlyView.
ABSTRACT Background Retinoic acid plays a critical role in spermatogenesis during both spermatogonial differentiation and spermiation. Mice lacking enzymes that synthesize retinoic acid, Aldh1a1/1a2, in the testes are infertile. WIN 18,446 reversibly inhibits spermatogenesis by inhibiting ALDH1A1/1A2 and is a promising approach to male contraception ...

Chromodomain Helicase DNA–Binding Proteins and Spermatogenesis: Current Advances

Andrology, EarlyView.
ABSTRACT Background Male infertility is a prevalent clinical condition, with approximately one‐third of cases classified as idiopathic, frequently stemming from impaired spermatogenesis because of dysregulated gene expression. Chromodomain helicase DNA‐binding (CHD) proteins are central chromatin remodelers that orchestrate this epigenetic regulation ...

Assessing a Model for a Complex Systemic Disorder—The Value of Male Mice With a Supernumerary X Chromosome for Klinefelter Syndrome Research

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 ...

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.

Diacerein Disrupts Testicular Homeostasis: The Essential Role of Basal Cytokines in Maintaining Sertoli Cell Integrity and the Immune Microenvironment

Andrology, EarlyView.
ABSTRACT Background Pro‐inflammatory cytokines, TNF and IL‐1B, are essential for testicular homeostasis. Diacerein, an anti‐inflammatory drug, inhibits these cytokines, impairing M2 macrophages and Leydig cells (LCs). However, its impact on Sertoli cells (SCs) and M1 (CD68) macrophages remains unknown.
