Seasonal Changes of Serum Gonadotropins and Testosterone in ... frontiersin.org Jan 9, 2020 5 facts
claimThe hypothalamic-pituitary-gonadal axis is susceptible to environmental rhythmicity, as annual hormone fluctuations are required for several animals to optimize reproduction timing.
claimEnvironmental rhythmicity affects the hypothalamic-pituitary-gonadal axis in several animals to achieve reproductive advantages.
procedureThe study 'Seasonal Changes of Serum Gonadotropins and Testosterone in...' analyzed testosterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) measurements collected between January 2010 and January 2019 using Chemiluminescent Microparticle Immunoassay, excluding subjects with factors interfering with the hypothalamic-pituitary-gonadal axis.
claimThe study on seasonal changes of serum gonadotropins and testosterone in males concluded that there are biannual or circannual fluctuations of serum luteinizing hormone (LH) and testosterone, which suggests a seasonal influence on the pituitary-gonadal axis in humans.
claimThe study on seasonal changes of serum gonadotropins and testosterone in males identified several strengths: it evaluated a large number of men living at the same latitude over a long time-frame, excluded participants with known diseases affecting the hypothalamic-pituitary-gonadal axis, and measured both testosterone and gonadotropins serum levels.

claimThe hypothalamic-pituitary-gonadal axis promotes sexual maturity, sperm production, and the development of secondary sex characteristics in human males, while maintaining spermatogenesis and sexual function throughout the male's lifetime.
claimThe hypothalamic-pituitary-adrenal axis is controlled by the hypothalamus and anterior pituitary, functioning similarly to the hypothalamic-pituitary-gonadal axis.
claimThe hypothalamic-pituitary-gonadal axis in men with aromatase deficiency provides evidence that circulating estrogens are required at the hypothalamic level for the integrity of gonadotropin negative feedback.
claimAn imbalance in the hypothalamic-pituitary-gonadal axis can result in infertility and hypogonadism.

claimIn fish, the lunar clock influences reproduction and involves the hypothalamus-pituitary-gonadal axis.
Physiology, Male Reproductive System - PubMed pubmed.ncbi.nlm.nih.gov May 1, 2023 1 fact
claimThe hypothalamic-pituitary-gonadal axis, formed by GnRH, FSH, LH, and testicular hormones, promotes and maintains sexual development and function in the male.
