ABSTRACT

The hypothalamic-pituitary-gonadal (HPG) axis orchestrates the complex hormonal regulation essential for reproductive health in both males and females. Dysregulation of this axis leads to infertility, menstrual disorders, gonadal dysfunction, and other endocrine abnormalities. Recent scientific interest has increasingly focused on phytotherapeutics- plant-derived bioactive compounds- for their potential to modulate the HPG axis, offering safer alternatives or adjuncts to conventional hormone therapies. This review provides a comprehensive evaluation of how phytochemicals influence key hormonal mediators within the HPG axis, including gonadotropin-releasing hormone (GnRH), luteinizing hormone (LH), follicle-stimulating hormone (FSH), testosterone, and estrogen. We explore experimental and clinical evidence supporting the efficacy of specific herbal agents such as Withania somnifera, Tribulus terrestris, Glycyrrhiza glabra, and Lepidium meyenii. Mechanistic insights into phytochemical actions, including receptor modulation, oxidative stress mitigation, and steroidogenic pathway regulation, are discussed. Finally, the review highlights current challenges, including bioavailability issues and safety considerations, and identifies critical future research directions to optimize phytotherapeutic interventions targeting the HPG axis for reproductive health improvement.
