About
In vitro fertilization (IVF) is an assisted reproductive technique to achieve pregnancy in subfertile couples of which the average success rate is only 25%. Mild ovarian stimulation treatment yields less oocytes, has less adverse effects but has a comparable clinical outcome compared to conventional stimulation treatment. There is high inter- and intra person variability in ovarian response and fertility outcome parameters after stimulation treatment and little is known about explanatory variables herefore.
Nutrition and in particular folate, or its synthetic derivative folic acid, is a B-vitamin which has been widely asssociated with reproductive outcome and subfertility. Therefore, in this study we aim to investigate the influence of preconception nutrition and folic acid use on ovarian response after mild/conventional stimulation treatment and to identify biomarkers in the follicular fluid which can indicate oocyte quality and other fertility outcomes.
