Assisted hatching of human embryos: a systematic review and meta-analysis of randomized controlled trials

Ultrasound for monitoring controlled ovarian stimulation: a systematic review and meta-analysis of randomized controlled trials

“…Only truly randomized RCTs were considered eligible; quasi-or pseudo-randomized trials were not included 17,18 . Studies that permitted inclusion of a participant more than once (crossover trials or 'per cycle' studies) were included only if data regarding the first cycle of each participant were available or if all consecutive cycles of each participant were performed in the same group; in all cases, the number of allocated women (rather than the number of cycles) was considered the denominator.…”

Time‐lapse embryo imaging for improving reproductive outcomes: systematic review and meta‐analysis

“…Assisted reproductive techniques (ART) have been widely used to treat this condition for more than three decades; however, both clinical‐pregnancy and live‐birth rates are still considered suboptimal, at approximately 35% and 25% per started cycle, respectively. In order to improve the overall treatment efficiency, several interventions are currently being studied.…”

Repeated implantation failure: a new potential treatment option

“…Several approaches have been suggested for the management of RIF. Treatment strategies, such as hysteroscopy, salpingectomy (in case of hydrosalpinx) and assisted hatching of the embryo, have been shown to improve ART outcomes in women with RIF [2][3][4]. Furthermore, it has been suggested that local 'endometrial injury' may improve pregnancy rates of RIF women undergoing ART [5].…”
