Influence of endometrioma size on ART outcomes.

Research Question: Does endometrioma size affect the number of oocytes retrieved after ovarian stimulation in women with endometriosis-related infertility undergoing IVF/intracytoplasmic sperm injection (ICSI)?

Design: Cohort study of infertile women with unilateral or bilateral endometrioma(s) associated with deep infiltrating endometriosis, undergoing their first IVF/ICSI cycle between January 2014 and November 2021. A total of 326 women with an adequate imaging work-up with transvaginal ultrasound and/or magnetic resonance imaging performed by senior radiologists before the start of ovarian stimulation was included. Prognostic factors associated with the number of oocytes retrieved were analysed.

Endometriosis and ART: A prior history of surgery for OMA is associated with a poor ovarian response to hyperstimulation.

Background: Many women whose fertility may have been impaired by endometriosis require assisted reproductive technology (ART) in order to become pregnant. However, the influence of ovarian endometriosis (OMA) on ovarian responsiveness to hyperstimulation has not been clearly established.

Objective: To evaluate the risk of a poor ovarian response (POR) to stimulation and ART outcomes in women with OMA.
