Study hypothesis
1. Micronutrient status influences the outcome of pregnancy and normal micronutrient status is necessary for a normal outcome
2. Micronutrient deficiency may prevent assisted conception, or if conception occurs there may be complications including early pregnancy loss and small-for-dates infant at birth
3. Assisted conception subjects who take ten weeks pre-conceptional Pregnacare Plus will produce more pregnancies that survive to 20 weeks than subjects on folic acid 400 mg in sub-fertile patients
