Dear patient, Thank you for your concern about your health, and welcome to HealthCareMagic. Pamsvax XL is called as Tamsulosin, medically speaking. This drug causes the smooth muscles lining the ureters (tubes) of the kidney to relax, thus allowing renal calculi (kidney stones) to be flushed out and excreted. Unfortunately, this same medication also causes the prostate gland (which is situated below the urinary bladder, where the urine collects) to relax. This causes the semen to flow backward into the bladder instead of forward out of the penis as in normal ejaculation during orgasm. This drug, Pamsval XL is thus causing your dry orgasms. Please see your urologist as regards this, and other alternative drugs. Ejaculation can still be achieved if the person practices an holding exercise during urination. Please discuss this too with your urologist doctor. Kindly follow the instructions. Take care of your health. I hope this helps you.
