Leptin Dynamics in Male Reproductive Health
Summary
Leptin, an adipokine produced primarily by white adipose tissue, serves as a critical link between energy status and the male reproductive axis. Acting both centrally, by modulating hypothalamic gonadotrophin-releasing hormone secretion, and peripherally, via receptors expressed on Leydig, Sertoli and germ cells, leptin influences testosterone synthesis, spermatogenesis and sperm function. At physiological levels leptin supports spermatogenic progression and maintains testicular homeostasis, whereas chronic hyperleptinaemia, as observed in obesity, is associated with hypogonadism, impaired blood–testis barrier integrity and subfertility. Intracellular signalling pathways including JAK2/STAT, PI3K/Akt and ERK mediate leptin’s effects on tight junction proteins and mitochondrial function within the testis. Dysregulated leptin dynamics contribute globally to male infertility, offering potential biomarkers for clinical assessment and targets for therapeutic intervention in both human medicine and animal breeding.

Leptin Dynamics in Male Reproductive Health publication trend
The graph below shows the total number of articles in leptin dynamics in male reproductive health across all publications each year (not limited to Nature Index journals).
Technical terms
Leptin: A 16 kDa hormone secreted by adipocytes that regulates energy balance and reproductive function through specific receptors.
Adipokine: A bioactive peptide released by adipose tissue that influences metabolic and endocrine processes.
Blood–Testis Barrier: A physical and biochemical barrier formed by tight junctions between Sertoli cells, essential for spermatogenic cell protection and microenvironment maintenance.
Reactive Oxygen Species (ROS): Chemically reactive molecules derived from oxygen that, in excess, cause oxidative damage to cells and tissues.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
