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.

Endocrine management of male subfertility

Indian Journal of Endocrinology and Metabolism, 2013
Infertility in a couple is defined as failure to conceive after 12 months of regular unprotected intercourses. Male infertility due to impaired spermatogenesis may result from hypothalamic, pituitary or testicular disorders.

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 ...

Low Free Testosterone Is Independently Associated With Long‐Term Mortality in Men With Chronic Spinal Cord Injury

Andrology, EarlyView.
ABSTRACT Background Testosterone deficiency is highly prevalent in men with chronic spinal cord injury (SCI) and is associated with obesity, sarcopenia, systemic inflammation, and metabolic dysfunction. However, the independent prognostic role of low testosterone in long‐term mortality in this population 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.

Prolactin in high‐metabolic risk pregnancies: Associations with maternal obesity and metabolic health

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Higher maternal BMI before and during early pregnancy is associated with lower prolactin levels across gestation and a reduced prolactin rise. Prolactin in pregnancy may reflect maternal metabolic health and has potential relevance to lactation outcomes.
