Fertility Control in Wildlife: Review of Current Status, Including Novel and Future Technologies

Area of Science:

• Wildlife biology
• Conservation science
• Veterinary medicine

Background:

• Effective wildlife conservation necessitates managing species, predators, and competitors.
• Human-wildlife conflict and the impact of invasive or feral species pose significant threats to biodiversity.
• Growing concerns for animal welfare are driving the adoption of non-lethal population control methods.

Purpose of the Study:

• To review current, historical, and emerging fertility control methods for wildlife.
• To assess the efficacy and applicability of various contraception techniques in conservation contexts.
• To highlight advancements and future directions in wildlife population management.

Main Methods:

• Comprehensive literature review of fertility control techniques in wildlife.
• Analysis of non-lethal methods including hormonal and surgical contraception.
• Evaluation of methods for both wild populations and captive breeding programs.

Main Results:

• Fertility control is increasingly favored for its non-lethal approach to population management.
• Existing methods show variable success, with some falling short of expectations.
• New contraceptive technologies under development offer promising solutions for conservation challenges.

Conclusions:

• Fertility control is a vital tool for managing endangered species and mitigating human-wildlife conflict.
• Advancements in contraception are crucial for sustainable wildlife populations and zoo breeding programs.
• Continued research and development are needed to overcome limitations and enhance the effectiveness of wildlife fertility control.
