Thawing of frozen semen straws
* The straw must be moved from the nitrogen container in to a thermos or thawing kit with thawing water of right temperature as quickly as possible.
* Check and control the water temperature before thawing each straw.
* Never thaw more than straw at each time.
* Remember to dry the straw with a paper after thawing! Water kills the sperm.
* Thawed straws are to be used ASAP.


* The syringe and the sheaths are to be kept at a temperature of 20-25 °C before inserting the straw.
* The syringe and the sheath must be prevented from getting damp.
* Avoid sudden temperature changes of the straw after inserted into the syringe. It can be good to put inside your clothes or under your arm.
