<b>Purpose:</b> The aims of this study were to find the difference in frequency between genders and to determine the correlation between age-related disease and other diseases in obstructive defecation. <b>Methods:</b> A consecutive series of<br>1,513<br>patients (343 males, 1,170 females) with obstructive defecation who undertook defecography and/or cinedefecography during 1 year period was analyzed. <b>Results:</b> The causes of obstructive defecation in males showed as spastic pelvic floor<br>syndrome<br>(SPFS) (48.3%), rectal prolapse (RP) (31.4%), descending perineum syndrome (DPS) (25.9%), enterocele or sigmoidocele (7.6%), and rectocele (7%). However, in females, the causes were rectocele (83.8%), DPS (49.2%), RP (37.6%), SPFS (32.5 %), and<br>enterocele or sigmoidocele (11.2%). The SPFS was negatively correlated with enterocele or sigmoidocele, DPS, RP in both genders, but SPFS had no statistical correlation with rectocele. DPS was correlated with RP in both genders and with<br>enterocele<br>or<br>sigmoidocele in females, but no statistical correlation was seen in males. The size of the rectocele showed a slight correlation with age in females (r=0.102, P=0.01). Age was correlated with rectal prolapse in females; however, it showed a<br>negative<br>correlation with SPFS in females. <b>Conclusions:</b> The frequency of diseases causing obstructive defecation is different between genders. Age may not play a role in aggrevating the diseases causing obstructive defecation. Further<br>pathophysiologic<br>study of gender differences in patients with obstructive defecation is needed.<br>
