What is the recommended temperature for semen samples to be maintained until they reach the lab?

The recommended temperature for semen samples to be maintained until they reach the lab is as close to body temperature as possible. This is because sperm cells are highly sensitive to temperature changes, and maintaining a temperature close to the normal human body temperature of approximately 37 degrees Celsius (98.6 degrees Fahrenheit) helps to preserve the viability and motility of the sperm.

When semen is stored or transported, it is crucial to avoid extreme temperatures, as cooler temperatures can slow down metabolic processes and potentially render the sperm nonviable, while excessively high temperatures can lead to cellular damage and decreased motility. Therefore, keeping the sample at a temperature close to body temperature ensures that the sperm remains functional and can be effectively analyzed upon arrival at the laboratory.

In comparison, other temperature options—like room temperature, freezing temperatures, or temperatures above 40 degrees Celsius—are likely to compromise the integrity of the sample, affecting test results and the overall quality of the sperm analysis.
