My fiancé and I were trying to conceive for five years. Finally we were told IVF would be our only best hope; as his sperm count was extremely low and I had PCOS. Whilst waiting for our IVF treatment to start, we took these supplements for three months, and two weeks before our injections were due to start for IVF, we found out we had conceived naturally! Taking these supplements was the only thing we changed, so there is no doubt that these products contributed to our miracle baby. Whilst taking them we did notice a change in our health and increases in our general energy levels too. Would wholeheartedly recommend this product.
