Leja is a small company and was founded in 1995. The head of the IVF clinic of the Amsterdam Free University thought that semen analyses could be done better. He invented the concept behind the Leja slides. After a long period of testing, the first slides to be officially marketed were released in 2002. Since then, a lot of product development has been taken place. New slide designs were developed. Also a physical occurrence was noted: the Segre-Silberberg effect. A special slide design was developed in order to compensate for this effect.
Currently a lot of research to constantly improve our products is conducted by the R&D department.
