Over the past few years my seminal fluid has declined during ejaculation to almost nothing. I am 75. My PSA is 4.6 and my doctor's digital exam says all is normal. I read somewhere that a decline in seminal fluid production can be an indicator of prostate cancer. I have either benign prostatic hyperplasia or irritable bladder syndrome based on symptoms of nighttime urination and daytime frequency particularly when I consume caffeine, etc.
Best wishes to all.
