Perinatal outcomes in 6640 singleton pregnancies after donor oocyte IVF across three continents over 7 years.

Purpose: Are trends in singleton donor oocyte IVF perinatal outcomes consistent over time among four international ethnically diverse infertility centers?

Methods: This retrospective cohort consisted of an infertility network of four international IVF centers across three continents. Singleton live births resulting from fresh and frozen donor oocyte embryo transfers from January 1, 2012 to December 31, 2018 were included. The main outcome measures were birth weight (BW), preterm birth (PTB), large for gestational age (LGA), small for gestational age (SGA) and gestational age (GA) at delivery.

The impact of IVF procedures on endometriosis recurrence.

Objective: In infertile women with endometriosis requiring an in vitro fertilization (IVF) procedure, the potential risk of an IVF-related progression of the disease remains a matter of debate. Thus, since available data on this issue are scanty and controversial, an observational study has been herein conducted in order to clarify this issue.

Study Design: We recruited 233 women with endometriosis who underwent IVF cycles in our unit.

Is the dimension of ovarian endometriomas significantly modified by IVF-ICSI cycles?

Information regarding the growth and development of endometriomas during IVF-intracytoplasmic sperm injection (ICSI) cycles is lacking. In this study, the aim was to estimate the influence of IVF-ICSI on the dimension of these cysts and to assess whether this treatment contributes to the manifestation of new endometriomas in patients already affected. Women were eligible if they had been diagnosed with ovarian endometrioma(s).

IVF-ICSI outcome in women operated on for bilateral endometriomas.

Background: The influence of previous conservative surgery for endometriomas on IVF-ICSI outcome is debated. Conflicting information emerging from the literature may be consequent to the fact that endometriomas are mostly monolateral. The contralateral intact ovary may adequately supply for the reduced function of the affected one.

Endometrioma and oocyte retrieval-induced pelvic abscess: a clinical concern or an exceptional complication?

The authors evaluated the risk of developing a pelvic abscess in a series of 214 in vitro fertilization cycles that were performed in women with endometriomas. This complication was never recorded, indicating that its risk is very low (0.0; 95% confidence interval, 0.
