[Analysis of prostate growth during human fetal period].
The objective of this study was to present quantitative data concerning prostatic growth during the foetal period (gestational age: 13 to 36 weeks) and to provide normal curves of the growth of the prostatic volume correlated with foetal age and weight, using the allometric method. This study was performed on 45 non-fixed human male foetuses, in a good state of preservation and not presenting any congenital malformations. The gestational age of the foetuses ranged from 13 to 36 weeks. Analysis of correlations showed that growth curves presented an angle less than 45 degrees, indicating that growth of the foetal prostate is slower than that of the individual as a whole. The authors also found a statistically significant correlation (p < 0.001) between prostatic volume and foetal weight during the foetal period.
