Impact of previous uterine artery embolization on fertility

Purpose of review To describe data on the effects of uterine artery embolization (UAE) on fertility. Recent findings UAE is used to treat postpartum hemorrhage (PPH) and fibroids. This effective therapy is replacing surgery in many cases. One of the main goals of UAE is to preserve the uterus and therefore fertility (pregnancies, menses and ovarian reserve). Pregnancies after this technique have been described. The main complications encountered during these pregnancies are not only PPH but also miscarriages and cesarean deliveries after UAE for fibroids. Conflicting results varying from completely well tolerated to serious complications such as definitive negative effect on endometrium and ovary function have been reported. Nevertheless, the series differ in that they included women of different ages and used different material for vessel occlusion (definitive microparticles of varying sizes, temporary pledgets of gelatine sponge, etc.). We discuss the impact of these differences on uterus vascularization and fertility. Summary UAE is an effective treatment for PPH and fibroids. Pregnancy is possible after UAE. Recurrent PPH is a serious and frequent complication. Synechia is also a potential complication. Desire of childbearing should be considered when choosing embolization or surgery and, in case of embolization, the choice of material used. Further studies on future fertility after UAE are needed as well as information on fertility after surgery.
