The aim of the study was evaluation of possibility of poly-ε-caprolacton (PCL) application as potential material for production of medical devices, as catheters for obtaining and transporting of embryos as well as dishes for embryos culture in vitro and covers for cryoconservation. The possible application of this biomaterial needs verification of its biological properties on embryos culture. The foil discs made of policaprolacton, thickness 0.5 mm, diameter 3.5 mm, were prepared in two forms: the baseline one (nPCL) and thermally modified by freezing with liquid nitrogen (mPCL). The verification of PCL bioconcordance was performed by evaluation of 102 pig embryos. To evaluate poly-ε-caprolacton bioconcordance we performed 5-day long culture of embryos on the evaluated material, not frozen (nPCL) and frozen in liquid nitrogen (mPCL) and additionally culture after short contact with poly-ε-caprolacton, lasting 15 minutes (nPCL-15). In all evaluated study groups the development of embryos was suppressed shortly after transfer to the culture with PCL. In the control group. 74%-78% of embryos reached blastocyst stage. Polycaprolacton cannot be used as the material for catheter production used in biotechnology of animal reproduction and other materials used for in vitro culture and cryoconservation.
