6 months back i have recovered from covid. after two months my semen was normal white colour. i was attacked with cold 3 months back and used predmet 8mg, after that my semen color is appearing light yellow till now. anything to be worried?

You have been sick for almost 6 months so liver problem needs to be ruled out as the cause with a simple blood test. Predmet does not change semen color, especially you are no longer taking it. I assume that you do not have any pelvic symptom (prostatitis can change semen color to yellow) and you do not use any herbal products which can also change semen color.

Yellowish sperm can occur with a prostate infection,when urine mixes with sperm or if you haven't ejaculated for awhile. I feel your sperm will return to a normal color since you don't appear to have any urinary or urethral symptoms.
