Spermatology and Andrology

The spermatology and andrology team investigates new analysis techniques for sperm cells of different species as well as improved media and technologies for semen preservation, both in liquid and frozen semen.

Current projects are concerned with fluorescent markers, proving the integrity and functioning of certain sperm organelles (acrosome, DNA, mitochondria). Also, new devices, which will allow quick and easy examination of various sperm functions in the production laboratory are developed by the spermatology and andrology team.

The correct and precise measurement of the qualitative and quantitative ejaculate parameters are the prerequisite for the production of semen doses with a correct number of viable sperm. The analysis of the quantitative semen parameters volume and concentration has been automated in professional semen laboratories by using scales, photometers and other tools. With computer assisted sperm analysis (CASA) systems like AndroVision®, the evaluation of semen motility in studs has been shifted from subjective estimation on the microscope, to an objective measurement with the CASA.

AndroVision® is a highly precise CASA system for standardised, interactive semen analysis. It has been developed under the auspices of Minitube CASA specialist Jochen Kirchner. AndroVision® not only provides the classic automated motility and concentration analysis, but also features the options of various fluorescence-based sperm functionality assays and an interactive, self learning morphology and morphometry module. It represents the next generation of CASA.
