ABSTRACT
In the past three decades, there has been a marked increase in the use of contraception worldwide. There is also a growing awareness of the urgent needs to improve the quality of family planning services and develop a wider range of methods for family planning that will meet the different and changing needs of individuals and couples throughout their reproductive lives. The challenge facing those working in the field is to respond adequately to these needs by paying due attention to quality of care in the service providing sector and developing new, safe, effective, acceptable and affordable methods for fertility control in the laboratories. The explosion of scientific advances in the past decades has generated an enormous amount of new knowledge about the physiology of human reproduction and information, critical to the development of new and improved methods of fertility regulation.
