I recently had changes in my semen analysis. Initially in March my first sa had 89% motility and this month it was 74%. My total volume increased from 111 million to 260 million as did everything thing else. My sperm has been watery and volume has been low for the past year. If I don’t ejaculate for 4 days than it will have a little bit more volume and less watery. I was recently diagnosed with pappiliary thyroid cancer and had my thyroid and lymph nodes removed. I am assuming that is the cause for the changes?
