Your “True” Paternal Age.

Path is an informational product only. For medical advice, talk to your doctor.

When sperm is received in our laboratory it is counted and purified to remove any contamination. The purity of the sperm is crucial for accuracy of the analysis.
After purification, sperm DNA is isolated from the sperm cells. All RNA is removed from the sample leaving pure sperm DNA.
Our sperm age calculation is based on changes in your sperm DNA that accumulate as you age.
To identify your sperm age (“true” age) your sperm’s DNA is put through two processes to identify important sites on specific genes associated with sperm age.
Your sperm DNA is then analyzed and compared to a large set of population data to conclude your sperm age.
