The term "Spermatorrhiea" refers to passing sperms in urine. It happens when a person doesn't masturbate , or indulge in sexual activity for a long period.
Many a time, a sticky colourless liquid is secreted when a male gets sexually excited. This is wrongly considered to be spermatorrhoea. Many people think passing this will cause loss of strength, as vital ingredients are lost. THIS IS AN ENTIRELY WRONG CONCEPT; THIS MISCONCEPTION IS KNOWN TO CAUSE PSYCHOLOGICAL PROBLEMS LIKE MENTAL DEPRESSION AND A FEELING PHYSICALLY WEAK.
