Tubal factor, cleavage stage and more than one embryo transferred were risk factors associated with ectopic pregnancy after assisted reproductive treatment.

Objective: Ectopic pregnancy is a well-known complication following in vitro fertilization with embryo transfer; studies have questioned, however, whether there are risk factors that could be identified before the procedure. The objective of this study was to investigate the possible risk factors involved in ectopic pregnancy following in vitro fertilization.

Methods: Retrospective case-control study performed at an assisted reproduction clinic in Brazil.

Ectopic pregnancy in left ovary and contralateral uterine tube diagnosed one week apart in In Vitro Fertilization with donor eggs: Case report.

Bilateral ectopic pregnancy is a rare clinical condition with an estimated prevalence of 1/200 000 in spontaneous pregnancies. Studies have found that In Vitro Fertilization (IVF) is related to ectopic pregnancy independently, but the incidence of tubal disease in the donor egg recipient population is thought to be significantly lower than in the standard IVF population. We report the case of a patient participating in the egg-sharing program, who was diagnosed with ovarian ectopic pregnancy, treated with surgery.

The antiapoptotic effect of galectin-3 in human endometrial cells under the regulation of estrogen and progesterone.

Galectin-3 (Gal-3), a ubiquitously expressed gene involved in many cellular processes, has been recently recognized as a factor related to endometrial receptivity. However, the precise biological function of Gal-3 in the endometrium and its regulation is still unclear. In this study, we detected the antiapoptotic role of Gal-3 in endometrial cells and the expression of Gal-3 regulated by estrogen and progesterone.
