Primary Outcome Measures

Name	Time	Method
<p>The following subjective and objective outcomes of surgical treatment will be<br /><br>examined:<br /><br>1. Position of the testes and any symptoms (pain)<br /><br>2. Size of the testes<br /><br>3. Echogenicity and blood flow of the testes<br /><br>4. Hormonal function of the testis<br /><br>5. Fertility potential by means of semen analysis</p><br>

Secondary Outcome Measures

Name	Time	Method
<p>Provided that the fertility potential of the test subjects is substantially<br /><br>low, it could be an indication to change or optimize the treatment of these<br /><br>patients. This could be an introduction to a prospective study of testis tissue<br /><br>in children who undergo primary surgery for bilateral undescended testes. By<br /><br>comparing two surgical techniques the advantages and disadvantages of these<br /><br>methods could be shown. </p><br>
