Abstract

OBJECTIVE:

To evaluate the effectiveness of metformin therapy in reducing early pregnancy loss in pregnant women with polycystic ovary syndrome (PCOS).

MATERIALS AND METHODS:

This is a prospective cohort study conducted in the Obstetric Department of the Gulf Medical College Hospital in Ajman, UAE, for a period of 3 years. This study involved 106 nondiabetic pregnant women with PCOS who became pregnant while using metformin. They were divided into two groups, namely, the group that received metformin throughout pregnancy (metformin group) and the group that discontinued using the drug once pregnancy started (control group). A comparison was made between the two groups of patients with respect to certain basal characteristics (age, body mass index, previous obstetric outcome, serum glucose with free testosterone). Statistical analysis was performed using Chi-square test to compare the differences between the two groups.

RESULTS:

There were 56 patients who received metformin during pregnancy (metformin group) compared with 50 patients who did not receive the treatment (control group). The rate of early pregnancy loss in the metformin group was 8.9% (5/56) compared with 36% (18/50) in the control group (p < 0.001). For patients in the metformin group with a history of previous miscarriage, the rate of pregnancy loss was 45% (35 cases/50 pregnancies).

CONCLUSION:

Metformin therapy in pregnant women with PCOS was associated with a significant reduction in the rate of early pregnancy loss.
