Kisspeptin as a test of hypothalamic dysfunction in pubertal and reproductive disorders

Andrology, EarlyView.
Abstract The hypothalamic–pituitary–gonadal axis is regulated by the gonadotropin‐releasing hormone pulse generator in the hypothalamus. This is comprised of neurons that secrete kisspeptin in a pulsatile manner to stimulate the release of GnRH, and, in turn, downstream gonadotropins from the pituitary gland, and subsequently sex steroids and ...

Identification of MEF2A, MEF2C, and MEF2D interactomes in basal and Fsk‐stimulated mouse MA‐10 Leydig cells

Andrology, EarlyView.
Abstract Background Myocyte enhancer factor 2 transcription factors regulate essential transcriptional programs in various cell types. The activity of myocyte enhancer factor 2 factors is modulated through interactions with cofactors, chromatin remodelers, and other regulatory proteins, which are dependent on cell context and physiological state.

Low testosterone in primary infertile men is associated with a history of maternal obesity during pregnancy: Findings from a cross‐sectional study

Andrology, EarlyView.
Abstract Background Maternal obesity increases offspring obesity risk, but limited data exist on its association with reproductive hormones in infertile males. Objectives To investigate the impact of maternal obesity during pregnancy on total testosterone levels in primary infertile men.

Vitamin D levels and biomarkers of male fecundity: A study from the Danish National Birth Cohort

Andrology, EarlyView.
Abstract Background Vitamin D is metabolised throughout the male reproductive system, suggesting a direct regulatory role of vitamin D in male reproduction. Objectives To investigate the association between plasma vitamin D levels at sperm ejaculation and during spermatogenesis and biomarkers of male fecundity in young men.

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

Andrology, 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.

Low testosterone levels in men at age 31 associates with future risk of prediabetes and type 2 diabetes: A birth cohort study

Andrology, EarlyView.
Abstract Objective We aimed to investigate the association of a low serum testosterone concentration with the risk of abnormal glucose metabolism (i.e., prediabetes and type 2 diabetes) in men at a 15‐year follow‐up. Study population and methods In a population birth cohort, men with low testosterone (testosterone < 12.1 nmol/L, n = 136) and normal ...

Muscle Strength and Power Changes With Gender‐Affirming Hormone Therapy

Andrology, EarlyView.
ABSTRACT Background Androgen receptors are highly expressed in upper body muscles, but changes in maximal muscle strength and power in major upper body muscles have not been investigated during gender‐affirming hormone therapy (GAHT). Objective To assess prospective changes in maximal muscle strength and muscle power from before and after 1 year of ...
