An insufficient flow of blood to the uterus would compromise nutritional supply to the foetus and waste removal from the foetus, and this can explain the heightened occurrence of low foetal birth weight (intrauterine growth restriction) and spontaneous abortions in women with Mullerian anomalies. Women with anomalies such as didelphys and bicornuate uteri present with a decreased uterine size and subsequent lower muscle mass. A diminished uterine capacity reduces the likelihood of the foetus reaching full-term development due to spatial constraints, explaining the higher rates of preterm births observed in women with Mullerian anomalies.
