  Purpose
The purpose of this study is to determine if the pre-operative levels of sex-hormones can be used to identify the varicocele patients who can expect improvements in their semen parameters following varicocelectomy.

Primary Outcome Measures:
  • Change in semen parameters [ Time Frame: February 2017 (anticipated duration of the study) ]

Secondary Outcome Measures:
  • Change in hormone levels [ Time Frame: February 2017 (anticipated end of the study) ]

Enrollment: 3
Study Start Date: February 2011
Estimated Study Completion Date: February 2017
Estimated Primary Completion Date: February 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Hormone/semen measurements before and after varicocelectomy
We will measure sex-hormone and semen quality in patients both before and after varicocelectomy. The purpose is to asses if preoperative hormone levels are predictive for who will have improved semen quality after surgery.
Procedure: Hormone and semen measurements before varicocelectomy
Before surgery we will measure sex-hormone levels and semen parameters. This will be repeated after the varicocelectomy to record any changes.
