There is real need worldwide to control the population growth of companion animals. Throughout the world and particularly in the United States, overpopulation of unwanted dogs and cats is a concern for many reasons. Feral populations pose risk to native species by spread of disease and predation. That unwanted animals are humanely eradicated is of concern to many persons. The need to control population growth has led to various approaches to contraception, including immunocontraception. Concerns regarding efficacy, duration of action, harm to the individual, and species specificity are among the issues being addressed. As new technologies emerge, ethical, political, and safety issues evoke differing opinions. It is hoped that in the near future, different strategies will be developed to solve this disturbing problem.
全球确实需要控制伴侣动物的数量增长。在世界各地，尤其是在美国， unwanted狗和猫的数量过多是一个令人担忧的问题，原因有很多。野生种群通过疾病传播和捕食对本地物种构成风险。许多人担心 unwanted动物会被人道消灭。控制数量增长的需求导致了各种避孕方法，包括免疫避孕。关于疗效、作用持续时间、对个体的伤害和物种特异性等问题正在得到解决。随着新技术的出现，伦理、政治和安全问题引发了不同的意见。希望在不久的将来能制定出不同的策略来解决这个令人不安的问题。
