Adenomyosis and ART

The goal of this clinical trial is to: * Prospectively investigate the association of Adenomyosis with fertility outcomes in relation to COH protocols for ART (long or ultra- long protocol) with a preventive high-dose anti-inflammatory progestin such as DNG and to assess their association with pregnancy and neonatal outcomes (preterm delivery,pre-eclampsia,Caesarean section,fetal malpresentation,small for gestational age,low birth weight and postpartum hemorrhage). * Understand how the endometrial interface by studying the response of progesterone and DNG stimulated decidualization markers, correlating them with the success of ART protocol stimulation and to pregnancy specific outcomes * Evaluate the immune changes during the implantation period and in the different trimesters of the pregnancies after ART conception.
