I am sure that everyone in the U. S. A. has viewed the plethora of TV commercials for this or that medication. Check or see what Your Doctor states regarding your need for the advertised medication. Then the disclaimers commence. The one that really excites me/generates the most interest is the statement "That if you use this medication you may experience a decrease in semen." Thus my question, who routinely measures the volume of semen that they produce? This is a possible topic that may require research or maybe the acquisition of a Government Grant to acquire data on which medications really do decrease the volume of semen.
