Study information
| Primary study design | Interventional |
|---|---|
| Study design | Randomised controlled trial |
| Secondary study design | Randomised controlled trial |
| Scientific title | |
| Study objectives | 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 |
| Ethics approval(s) | Not provided at time of registration |
| Health condition(s) or problem(s) studied | Female infertility |
| Intervention | Randomised 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. |
