  • Oocytes remain viable in the ovary for ~24 h including time of shipment.ÊTissue from females found >12 h after death should be sent directly to Dr. Karen Terio.
  • Spermatozoa will remain viable for slightly longer depending on temperature.ÊTissues from males can be used if found within ~18 h, if ambient temperature is 30¡ C.


  • Gonads from Pallas cats will only be useful if recovered November thru April due to their reproductive seasonality.


  • As soon as possible after death, remove the ovaries or testes.ÊFor testes, please include most of the spermatic cord.
  • Place the gonads in a clean, preferably sterile, container (specimen cup, ziplock bag, test tube, etc.) and cover with enough sterile saline to keep the tissue moist in transit.


  • Place the samples in a small styrofoam cooler along with 1-2 ice packs.ÊWrap the ice packs in several layers of paper towel so the samples do not get cooler than ~5¡ C.ÊExcess space can be filled with styrofoam pellets or bubble wrap, but do not leave too much space between the samples and the ice packs.
