# Gonad Dose Assessment of Patients Undergoing Pelvic Radiotherapy
## 3 Results
All patients who underwent ovarian transposition complied with the maximum dose limit (V\({}_{7.5\,\mathrm{Gy}}\) < 26%), suggesting that the volume receiving 7.50 Gy should have been less than 26%, as well as the mean dose limit (<8.80 Gy), according to the COKAIR project [25]. Two patients without ovarian transposition complied with these limits, while the rest did not. \begin{table}

Table 5: Technique and maximum and mean doses in Gy for the right and left ovaries of females with rectal tumors. No statistically significant differences were detected between the doses to the left and right ovaries (\(p>0.05\)). Statistically significant differences were observed between the maximum and mean doses for both the right (z = \(-4.704\); \(p<0.001\)) and left ovaries (z = \(-4.703\); \(p<0.001\)), with the maximum dose being significantly higher in both cases. No statistically significant differences were found between the VMAT and 3 DCRT techniques regarding the maximum and mean doses delivered to both the right and left ovaries (\(p>0.05\)). There were statistically significant differences between females who underwent ovarian transposition and those who did not, regarding both the maximum and mean doses to the right and left ovaries (\(p<0.05\)). Table 8 shows, on average, a reduction of 39 Gy in the maximum and mean doses to the right ovary and a reduction of 30 Gy in the maximum and mean doses to the left ovary in females who underwent ovarian transposition. \begin{table}
