Biotherapy using Sperm Cell-oriented Transportation of Therapeutics in Female Reproductive Tract Cancer.

Female reproductive tract cancers like ovarian, cervical, vaginal, etc. have led to a serious concern for reproductive health as well as an increase in physical and psychological stresses amongst women. Various conventional techniques like surgery, radiation and chemotherapy are employed but possess limitations such as organ toxicity, infection, nausea, vomiting, etc. Also, several nanotechnology-based synthetic vehicle delivery systems like liposomes, nanoparticles, etc. are used but they lack targeting efficiency that results in poor propulsion and control. Therefore, there is a need for naturally-driven drug carriers to overcome such limitations. Sperm-based drug delivery is the new area for targeted delivery that offers self-propulsion to tumor sites, higher biocompatibility, longer lifespan and increased tissue penetration with enhanced localization. Drug-loaded sperm cells are harnessed with micro/nanomotor that will guide them to the intended target site. The critical analysis of the sperm-based drug delivery system was executed and summarized along with the current challenges. This article deals with the art of delivering the anticancer drug to female reproductive cancer sites with proof-of-concept-based research data and critical discussion on challenges in formulating the sperm-based delivery with a future perspective.
