Assessment of vascular endothelial growth factor, basic fibroblast growth factor, and transforming growth factor levels in amniotic fluid.

Objective: To measure amniotic fluid levels of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), and transforming growth factor (TGF)-beta2 and to characterize their levels with respect to advancing gestational age and pregnancy-related complications.

Study Design: Amniotic fluid was collected from a total of 37 patients, 2 of whom had twin pregnancies. Twenty-seven specimens were collected in the second trimester and 10 specimens were collected in the third trimester.

Association between time from endometriosis surgery and outcome of in vitro fertilization cycles.

Objective: To evaluate the effect of time from surgery on the outcome of subsequent in vitro fertilization (IVF) cycles in endometriosis patients.

Study Design: One hundred five women treated surgically for endometriosis and who underwent 252 IVF cycles were included. Approximately 1/2, 1/4 and 1/5 of the study group underwent 1, 2 and 3 cycles, respectively.
