Advancing CRISPR technologies in reproductive biology

Abstract

Clustered regularly interspaced short palindromic repeats (CRISPR) technology, a transformative tool for genetic modifications, gene therapy, and treating various genetic diseases, has recently garnered significant attention for its applications in reproductive biology. In this realm, researchers are focusing on addressing gynecological disorders, refining assisted reproductive methods, and conducting precise germ cell editing. The potential impact of CRISPR in these areas is monumental; however, several research gaps persist, demanding further investigation into the long-term effects, safety implications, and unintended consequences of its applications in reproductive biology. Refining the precision and specificity of CRISPR technology is a critical aspect that necessitates addressing challenges such as off-target effects and cytotoxicity. These considerations underscore the urgency for ongoing research efforts to ensure the efficacy and safety of CRISPR applications. In addition, the establishment of robust regulatory frameworks and oversight mechanisms specific to CRISPR in reproductive contexts is imperative to guarantee the responsible and ethical use of this powerful technology. This comprehensive review delves into the advantages of CRISPR over traditional gene editing methods, providing insights into its applications in embryos, pluripotent stem cells, and germline cells. It further explores the risks and limitations associated with CRISPR, including ethical concerns related to designer babies and eugenics. The article sheds light on the regulatory landscape governing new CRISPR applications in reproductive biology, emphasizing the continuous improvements in the efficiency and specificity of CRISPR technology. In contributing to the ongoing discourse, this review aims to inform and guide the responsible and effective application of CRISPR in the dynamic field of reproductive biology.
