DESIGN Retrospective review and prospective study. SETTING Private IVF clinic. PATIENT(S) Two hundred forty-nine couples undergoing first IVF and/or ...

DESIGN Retrospective analysis of IVF treatments. SETTING Hospital IVF clinic. PATIENT(S) Women with infertility according to ovarian reserve and endocrine profile were selected for different treatments. IN...
