最近几十年来,世界人口的增长速度较快。许多国家都在纷纷制订自己的计划生育措施,推广各种节育技术。在目前世界40多亿人口中,共有育龄妇女7亿,而有生育力的男性有12亿。然而对男性抗生育技术的研究却比较少,进展也较缓慢。70年代在男性避孕药、器械避孕和免疫避孕等方面的研究有了较大的进展。有些国家已经建立了人类生殖内分泌学、生殖生理学和男性学(Andrology)专业。我国在计划生育科研工作方面,男性生殖生理学等基础理论研究已经开展,男用口服避孕药的研究工作也有了重大的突破。男性的生殖机能是一个相当复杂的生理过程,在这个过程中打乱或干扰了任何一个环节都可影响
The world population has been growing at a rapid rate in recent decades. Many countries are developing their own family planning measures to promote various birth control techniques. In the current 4 billion people in the world, there are 700 million women of childbearing age, while there are 1.2 billion men of fertility. However, male anti-fertility technology research is relatively small, the progress is relatively slow. In the 1970s, great progress has been made in the research on male contraceptives, device contraception and immune contraception. In some countries, human reproductive endocrinology, reproductive physiology and andrology have been established. China’s research work in family planning, male reproductive physiology and other basic theoretical research has been carried out, men’s oral contraceptive research has also made a major breakthrough. Male reproductive function is a very complex physiological process, in the process disrupted or interfere with any one step can be affected
