Produced by both normal and malignant prostate cells, PSA functions to liquefy semen in the seminal coagulum allowing sperm cells to move freely and to dissolve the cervical mucus permitting the sperm cells migration to the uterus.
Levels of PSA are low in healthy men but elevate in the presence of prostate cancer and other mentioned conditions.
PSA screening is recommended for men over 40 years old that would be considered high risk: Black men, men with germline variants of BRCA1 or BRCA2 and/or men with a family history of prostate cancer.
For those not considered to be high-risk, screening is still recommended between the ages of 55-70.
