1. Urinary Tract Infection or Irritation
If you have undergone any medical procedures involving the bladder or urethra, it may cause your prostate to produce more PSA. If this applies to you, it is important to give that area time to heal before going for a PSA test.
Normal PSA levels tend to vary between people of different age groups. For example, older men’s regular PSA may be slightly higher than younger men’s.
3. Size of the Prostate
A healthy prostate produces lower levels of PSA. If a man has a larger prostate, they may have a higher level of PSA.
Some medications are known to reduce PSA levels, such as dutasteride, which is used as a medical treatment for benign prostate enlargement. It is highly recommended that you always let your physician know of all the medications you are currently taking.
