The main purpose of this study is to estimate the effect of adding Tea-N-Tris (TES) to the freezing buffer for miniature pig sperm. In particular, we attempted to identify the association between the MMPs expression and the fertility and viability of frozen sperm from each extender (LEY (Lactose Egg-Yolk), TLE (TES + LEY), TFGE (TES + Fructose + Glucose Egg-Yolk)). In accordance with this, Hypoosmotic Swelling Test (HOST) respond test was the lowest among sperms frozen in LEY while the highest HOST respond was observed among sperms frozen in TLE. Furthermore, we observed MMPs expression in all sperm groups, with pro-MMP showing lower expression than active MMPs. The expression of MMP-9 and MMP-2 was the highest in sperms frozen in LEY, Meanwhile, sperms from the TFGE and TLE group showed lower level of MMP-9 and MMP-2 expression in the order of TLE being the lowest. LEY group showed lower rate of blastocyst development than the TES supplement group, although the difference was not statistically significant. Meanwhile the rate of blastocyst development appeared similar when sperms from TLE and TFGE group were used for IVF. Together, these results indicate that adding Tea-N-Tris to the sperm freezing buffer only suppresses MMPs protein activation but also maximize in-vitro fertility, providing a means to improve the success rate in the in vitro manipulation of miniature pig sperm.
