title: Comparing the length of penile mucosa in men with and without premature ejaculation.
abstract: BACKGROUND
  Premature ejaculation is one of the prevalent disorders in men; almost one out of three men between 18 and 59 years old have this disorder with its leading sequel such as lack of self-confidence, anxiety, depression and unsatisfactory intercourse in men and their partners. This study aimed to compare the length of penile mucosa in men with and without premature ejaculation.
  
  
  METHODS
  Three hundred and eighty patients referring to our hospital from March 2009 to March 2010 were enrolled in the study. First group comprised 190 men with premature ejaculation and second group included 190 men without premature ejaculation as control group that were chosen randomly. A questionnaire was designed to collect data and was completed for both groups. Height, weight, body mass index (BMI), length of penile mucosa, length of penis and intravaginal ejaculation latency time (IELT) were measured.
  
  
  RESULTS
  The mean IELT in premature ejaculation group and control group were 47.58 ± 29.55 and 410.38 ± 190.2 s, respectively (p = 0.001). The mean penis length in premature ejaculation group and control group were 127.25 ± 16.23 and 127.03 ± 17.42 mm, respectively (p = 0.901, with nonsignificant difference); the mean penile mucosa in premature ejaculation group was 33.83 ± 11.54 mm and in control group was 31.40 ± 11.97 mm (p = 0.014, with significant difference).
  
  
  CONCLUSIONS
  Longer penile mucosa can be one of the factors in causing premature ejaculation.
