Active Comparator: Sildenafil group Includes 45 women who received Sildenafil citrate (Respatio(R) 25mg tablets four times daily for 24 days preconceptionally starting first day of previous period) and folic acid (Folic acid(R) 0.5mg tablets once daily for 3 months preconceptionally). | Drug: Sildenafil group Respatio(R) 25mg tablets four times daily for 24 days preconceptionally starting first day of previous period |
Active Comparator: Control group Includes 45 women who received placebo oral tablets (apparently identical to Respatio(R) 25mg tablets, four times daily for 24 days preconceptionally starting first day of previous period) and folic acid (Folic acid(R) 0.5mg tablets once daily for 3 months preconceptionally). | Drug: Control group Placebo tablet apparently identical to Respatio(R) 25mg tablets, taken four times daily for 24 days preconceptionally starting first day of previous period |
