Abstract

The clinical practice of gynaecology and obstetrics has historically been guided by anatomy, physiology, and empirical observation. However, the 21st century has witnessed a paradigm shift, revealing that the fundamental principles of biophysics and biochemistry are the unseen pillars supporting every aspect of female reproductive health. This article comprehensively reviews the critical importance of these disciplines in understanding and managing both normal physiological processes and pathological conditions. We explore the biophysical forces governing folliculogenesis, ovulation, and fallopian tube transport, alongside the intricate biochemical signaling of the hypothalamic-pituitary-ovarian (HPO) axis. In obstetrics, the roles of biochemical markers in prenatal screening and the biophysics of uteroplacental blood flow and fetal membrane integrity are examined. Furthermore, the article delves into the biophysical basis of diagnostic imaging, the biochemical pathogenesis of conditions like preeclampsia and endometriosis, and the revolutionary impact of biophysical techniques in assisted reproductive technologies (ART). The integration of biophysics and biochemistry is not merely ancillary but central to the advancement of personalized, predictive, and effective care in women’s health, paving the way for future innovations in diagnostics and therapeutics.
