The direct response of the gonads to cues of stress in a temperate songbird species is season-dependent. [PDF]
, 2013 The gonadotropin releasing hormone (GnRH) system in the hypothalamus is often considered the final point in integration of environmental cues as they pertain to the reproductive axis.

Luteinizing Hormone Receptors: Specific Binding of Human Luteinizing Hormone to Homogenates of Luteinized Rat Ovaries [PDF]
Proceedings of the National Academy of Sciences, 1972 Binding of human [ 125 I]luteinizing hormone to homogenates of luteinized rat ovaries is dependent upon time, temperature, and pH and is saturable. Injection of human chorionic gonadotropin in vivo or addition of unlabeled human chorionic gonadotropin or human or ovine luteinizing hormone

Advanced Science, EarlyView.Psychological stress activates the sympathetic–adrenal axis, elevating norepinephrine (NE) and suppressing reproductive hormones, thereby impairing male reproduction. Excess NE overactivates and desensitizes β‐adrenergic receptors (β‐ARs), triggering Sertoli cell ferroptosis and disrupting spermatogenesis.

Advanced Science, EarlyView.This study demonstrates that patients with PCOS exhibit altered gut microbial profiles, and FMT from PCOS patients induces PCOS‐like symptoms in mice. Specifically, gut dysbiosis reduces 3‐HAA levels in the context of PCOS. Administration of 3‐HAA to mice alleviates PCOS by promoting de novo NAD+ synthesis.

Utility of Ovarian Tumour Marker Cancer Antigen-125 and Endocrine Hormonal Status in Polycystic Ovary Syndrome [PDF]
Journal of Clinical and Diagnostic Research, 2018 Introduction: Polycystic Ovary Syndrome (PCOS) is the most common endocrinopathy in women of reproductive age. Women with PCOS are at increased risk of reproductive abnormalities with a prevalence of up to 10%.

Pesticide Exposure Alters Follicle-Stimulating Hormone Levels in Mexican Agricultural Workers [PDF]
, 2005 Organophosphorous pesticides (OPs) are suspected of altering reproductive function by reducing brain acetylcholinesterase activity and monoamine levels, thus impairing hypothalamic and/or pituitary endocrine functions and gonadal processes. Our objective

BHLHE40 Cooperates with GATA2/3 to Control Human Syncytiotrophoblast Lineage Differentiation
Advanced Science, EarlyView.BHLHE40 interacts directly with GATA2 and GATA3 and co‐occupies genomic loci critical for STB differentiation and function. BHLHE40 also affects GATA2/3 binding at enhancer and promoter regions. Moreover, BHLHE40 is potentially involved in genome‐wide remodeling of H3K4me3 and H3K27ac chromatin landscapes through GATA2/3 recruitment, activating ...
