Nanoparticle-Based Therapeutics for Disorders of the Female Upper Genital Tract: A Comprehensive Review

The female reproductive system is susceptible to a range of disorders, including uterine fibroids, endometriosis, polycystic ovarian syndrome (PCOS), and various gynecological cancers. Traditional drug delivery methods often face challenges such as limited bioavailability, systemic side effects, and poor targeting due to biological barriers like mucus layers, fluctuating pH, and immune responses. Nanotechnology offers a transformative approach to overcome these limitations by enabling site-specific and controlled drug release. This review explores the anatomy of the female upper genital tract (UGT), common associated disorders, and the barriers that hinder effective drug delivery. It highlights the potential of nanoparticle-based drug delivery systems—such as liposomes, polymeric nanoparticles, dendrimers, and nanoemulsions—to improve therapeutic outcomes. Nanoparticles can penetrate mucosal barriers, increase drug retention time, and allow targeted therapy through surface modification and responsive release mechanisms. Specific applications of nanocarriers in treating cervical, ovarian, and endometrial cancers, as well as non-malignant conditions like PCOS, fibroids, and salpingemphraxis, are discussed in detail. Examples include gold and zinc oxide nanoparticles for cancer treatment, curcumin-loaded NPs for PCOS, and magnetic NPs for targeted gene delivery. Despite promising preclinical results, concerns regarding toxicity, hormonal disruption, and regulatory challenges remain and warrant further clinical evaluation. In conclusion, nanotechnology holds immense potential to revolutionize female reproductive healthcare by offering non-invasive, efficient, and safer alternatives to conventional therapies. Continued interdisciplinary research is essential to translate these innovations into clinically viable treatments for improving women’s reproductive health outcomes.
