Primary Outcome Measures:
  • the quality of semen and the level of sexual hormone [ Time Frame: before and three and six months after surgery ] [ Designated as safety issue: Yes ]
    The semen analyses and were sexual hormones determinations conducted before and three and six months after surgery.Then the quality of semen and the level of sexual hormone before and after surgery were compared.

  • complications [ Time Frame: one, three and six months postoperation ] [ Designated as safety issue: Yes ]
    the complications such as recurrence, hydrocele,orchiatrophy and wound infection were assessed one, three and six months postoperation. Color doppler ultrasonography and physical examination are the main methods to assess the complications


Secondary Outcome Measures:
  • If there was pain, visual analogue scale,Numerical rating scale and verbal rating scale would be used to evaluate pain intensity. pain intensity [ Time Frame: before and one,three and six months after surgery ] [ Designated as safety issue: Yes ]
    If there was pain, visual analogue scale,Numerical rating scale and verbal rating scale would be used to evaluate pain intensity.


Other Outcome Measures:
  • general information [ Time Frame: before surgery ] [ Designated as safety issue: No ]
    Before surgery, all patients were diagnosed by physical examination and testified by color Doppler ultrasound. And we documented the patients' age, left unilateral or bilateral and the grade of varicocele
