Effects of ovarian puncture for in vitro maturation on subsequent in vitro fertilization cycle in women with polycystic ovaries.

We conducted a case-control study and compared the results of IVF treatment in two groups of women with polycystic ovaries. The first group consisted of 42 women who were previously treated unsuccessfully with in vitro maturation (IVM), and the second group, 48 others with no previous IVM (control group). We included the first IVF cycle only. Our preliminary result shows that previous ovarian puncture for IVM is associated with improved number of mature oocytes retrieved and total number of embryos produced. However, it is not associated with a better pregnancy rate. A larger study is needed. Copyright (c) 2010 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.
