BOOK TITLE: Principles and Practice of Assisted Reproductive Technology
The objective of this chapter is to introduce the micromanipulators. A micromanipulator is a device which is used to physically manipulate the microscopic structures under a high magnification, where a level of precision of movement is necessary which cannot be achieved by the unaided human hand. The use of micromanipulator for the manipulation of cells by biologists and physiologists dates back more than a century. It was GI Kite who reported first microinjection of sperm into the oocyte of starfish in 1914. A series of experiments was carried on different species demonstrating major species differences. Different types of manipulators have been developed by different manufacturing companies from time to time with subsequent improvements with each model.
