Semen analy­sis is the cen­tral part of androl­ogy lab­o­ra­tory diag­no­sis. Car­ry­ing out the exam­i­na­tion accu­rately while min­i­miz­ing  con­found­ing fac­tors is a pre­req­ui­site for attain­ing reli­able results. Analy­ses need to be per­formed using stan­dard­ized tech­niques which are reg­u­larly sub­jected to con­tin­u­ous inter­nal and exter­nal qual­ity con­trol. QuaDeGA offers such a pro­gramme for exter­nal qual­ity control.

The Ger­man Fed­eral Med­ical Board has recently included qual­ity assur­ance of the ejac­u­late in its Guide­lines for Per­form­ing Lab­o­ra­tory Analy­ses (RiLiBÄK) and has rec­og­nized QuaDeGA as a Ref­er­ence Insti­tu­tion. As of Jan­u­ary 1, 2011 every lab­o­ra­tory in Ger­many car­ry­ing out analy­ses of the ejac­u­late is required to par­tic­i­pate in an exter­nal qual­ity con­trol pro­gramme. After suc­cess­ful com­ple­tion of the qual­ity con­trol pro­gramme, QuaDeGA will issue the required certificate.
