Study objectives1. 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
Ethics approval(s)Not provided at time of registration
Health condition(s) or problem(s) studiedFemale infertility
InterventionRandomised controlled trial of folic acid (400 mcg) versus Pregnacare Plus (contains folic acid 400 mcg and 17 other micronutrients) given for 10 weeks prior to assisted conception and follow-up to 20 weeks in those that become pregnant. Subjects will also be monitored for nutritional status.
