Fluctuations in regulation of female reproductive hormones such as Estrogen and progesterone are known contributors to the formation of decidual cast. Endocrine imbalance of female reproductive hormones occurs due to polycystic ovarian syndrome (PCOS) or medications that interfere with hormonal balance such as oral contraceptives.

Uterine irregularities include fibroids or anomalies. Uterine anomalies are structural abnormalities of the uterus that cause variation of its shape along with weakness of the wall at the sites of deformation. Uterine fibroids or adenomyosis cause increased shedding of the uterine lining as it exerts pull on the uterine wall along with rupturing itself. This increases the likelihood of decidual cast formation that further threatens the uterine functions in the presence of an underlying reproductive condition.

3. Pregnancy-related factors:

Decidual casts are of common occurrence in pregnancy related cases such as abortions, miscarriages, or ectopic pregnancies. Retained products of conception stimulates the formation of decidual cast during the sequential menstrual cycles.
