Despite alarming statistics on rapid biodiversity loss, concerted conservation efforts continue to offer opportunities to reverse this trend. Reproductive sciences play a crucial role in addressing threats to wildlife species from anthropogenic activities, including habitat destruction and other environmental changes. While conservation biology encompasses diverse areas, from ecology to biotechnology, reproductive experts often find themselves at the intersection of multiple disciplines. They collaborate with conservation partners, centralizing critical information to develop effective strategies for preserving and restoring animal species to their natural habitats. Persistent efforts to enhance our understanding of reproductive biology in understudied and underreported species, ranging from pollinators to fish to rare mammals, have resulted in a growing body of literature demonstrating the remarkable diversity of reproductive strategies across animal taxa. While classical research approaches remain essential, the integration of advanced tools such as high-throughput sequencing of DNA, RNA, proteins, and microbiomes has accelerated progress in this field. Significantly, a more precise understanding of wildlife reproduction facilitates the implementation of evidence-based conservation actions to sustain small populations and potentially assist their reproductionReproduction. In recent years, the integration of ethical considerations into research on wildlife reproduction and subsequent conservation actions has been carefully deliberated. Incorporating ethical frameworks, in conjunction with consultation, engagement, and participation of local communities, is crucial and expected to lead to more impactful decisions and successful implementation of conservation technologies.
