MMC Sperm (MultiMedia Catalog Sperm) is an automated image analysis software package for sperm quality analysis according to parameters recommended by WHO (World Health Organization). This software is based on our MultiMedia Catalog with addition of dedicated routines for semen analysis. MMC Sperm represents the basis for Computer Assisted Sperm Analysis System (CASA) to be used in human reproduction (in andrology labs, ART, IVF clinics) for estimation of fertility/infertility and understanding its causes as well as in veterinary and animal, bee, fish breeding for calculation of sperm doses for artificial insemination.
