I was diagnosed with some 3-4mm kidney stones in both of my kidney, having consulted with one of the doctors nearby, he had prescribed me urimax 0.4 ( tamsulosin ), i took the medicine for 10 days and i stopped it on 10th of July, but since then my semen volume has not been normal, sometimes the ejaculate volume is less even nil, it's been 3 weeks/20 days since i have stopped the medicine, is there something to worry about, does it take this long for the medicine to wear off? What to do to fix this issue?
