CLEVELAND - March 29, 2021 - PRLog -- Cryopreservation of Sperm Ensured During Transport

A farmer breeding cattle was using artificial insemination methods to ensure optimum fertility and herd quality while avoiding the cost of keeping or borrowing a stock bull.
To guarantee high fertility rates, the farmer needed to keep the bull semen stored, transported, and ready for implant at the necessary sperm storage temperature.

If storage over 4 days was required, the semen was kept and transported in special containers filled with liquid nitrogen that needed to remain at a constant temperature of -196°C (-320°F). For successful artificial fertilization to occur, the deep-frozen semen needed to be thawed prior to implantation and maintained at 25°C (77°F) for a maximum of around 2 days.
The farmer could not afford to run the risk of receiving infertile semen, so it was important for him to carefully control the sperm storage temperature. For storing deep-frozen semen, it was most effective to monitor the nitrogen level in the container.


The farmer installed a SwiTrace IPMT8.CRYO multi-use ultra-low temperature data logger on the liquid nitrogen storage container. The stainless-steel tip of the external sensor was inserted into the container at a depth to match the nominal level of the liquid nitrogen. The logger itself was placed in a small plastic enclosure with a clear lid to allow easy viewing.

The IPMT8 supported many features which allowed the farmer to make decisions immediately, including a clear LCD display and active & alarm LEDs, incorporating multi-function viewing to see real-time data. This evidence helped the farmer to obtain financial compensation from his insurance company.


The temperature logger's 0.01°C (.018°F) external sensor resolution provided an effective early warning system. The IPMT8 also recorded temperatures that thawed or fresh semen had been exposed to, and the farmer could choose to configure the data logger in either Celsius or Fahrenheit.

Free iPlug Manager software was provided with the IPMT8 for easy programming and the PDF download feature allowed convenient retrieval of recorded sperm storage temperature. This user-friendly, intuitive software enabled the farmer to quickly customize the data logger.


The farmer benefitted in several ways from installing the IPMT8 temperature data logger in the semen storage container. The farm experienced increased fertility in its livestock due to the temperature logger's high-accuracy readings, which in turn led to savings in feed and labor costs.
