Yes, evidence suggests that continuing metformin throughout the first trimester in women with PCOS can significantly reduce the risk of early miscarriage and increase live birth rates, with studies showing substantial drops in miscarriage rates compared to stopping the medication. While it helps with pregnancy complications, more high-quality research is needed, especially regarding long-term effects on offspring, but it's generally considered safe and helpful for managing insulin resistance in PCOS pregnancies, say experts from the Endocrine Society and other research groups.
Compared with no treatment, continuing metformin treatment throughout the first trimester of pregnancy may reduce the risk of miscarriage and increase live birth rates in women with PCOS. Continuation of metformin seems to have greater clinical benefit than discontinuation of metformin after a positive pregnancy test.
If you have PCOS, what can you do to minimise the risk of miscarriage?
Among women receiving metformin, including those with live births and normal pregnancy for at least the first trimester, 1 of 10 (10%) had first-trimester spontaneous abortion compared with 73% in 22 previous pregnancies without metformin (P<. 002).
In summary, no evidence currently in the literature shows that use of metformin in women with PCOS is associated with increased risk of malformations. Most of the studies applicable to PCOS restricted exposure to the first trimester, ie, metformin was discontinued as soon as pregnancy was diagnosed.
Polycystic ovary syndrome affects 6 to 15% of reproductive age women worldwide. It is associated with increased risk of miscarriage, gestational diabetes mellitus, hypertensive disorders of pregnancy, preterm delivery, and birth of small for gestational age infant.
Because metformin can help regulate periods, people with PCOS may become pregnant more easily. If you are sexually active and not trying to become pregnant, be sure to also use a reliable form of birth control. Metformin can cause lower levels of the vitamin B12.
Overall, metformin use during pregnancy is considered safe, and no association has been demonstrated between first-trimester metformin use and the increased risk of congenital abnormalities.
In many cases, the cause of a miscarriage is not known and you would not have been able to prevent it.
Recurrent pregnancy loss can have a variety of causes including: Abnormalities in the uterus, such as a uterine septum, fibroids or retained pregnancy tissue. Cervical insufficiency, which causes losses late in pregnancy. Thyroid conditions, diabetes or high levels of the hormone prolactin.
At what week commonly do miscarriages happen with PCOS? Pregnancy loss is common during the first trimester (first 12 weeks).
There is no evidence of reduction in the risk of miscarriage in women prescribed bed rest. HCG administration as an alternative care for threatened miscarriage was more effective than bed rest in the Harrison study but this benefit is not confirmed when compared with placebo.
PCOS is often considered a high-risk condition for pregnancy due to the associated complications that can arise for both you and your baby.
There is no particular time limit for the use of Metformin. However, if you haven't seen any benefits after six months of use, we may discuss discontinuing the drug.
Research has shown that taking progesterone may prevent a miscarriage if you: are bleeding in early pregnancy (before 12 weeks) and.
Metformin treats PCOS by lowering insulin and blood sugar levels. This can also improve ovulation and encourage regular periods, even if you do not have diabetes. Metformin is available on prescription as tablets, as a liquid that you swallow and as sachets of powder that you dissolve in a drink.
Your risk of miscarriage is greatest between weeks 0 and 10. In the early days of pregnancy, you likely don't yet know you're pregnant.
Lifestyle Changes: A balanced diet, regular exercise, and stress reduction can help manage PCOS symptoms and reduce miscarriage risk. Medications: Ovulation-inducing medications, insulin-sensitising agents like Metformin, and progesterone supplements can improve pregnancy outcomes.
Nutrients and vitamins to prevent miscarriage or help reduce miscarriage risk
Use of metformin throughout pregnancy in women with polycystic ovary syndrome (PCOS) has shown to reduce the rates of early pregnancy loss, preterm labor, and prevention of fetal growth restriction.
Metformin has no known fetal teratogenicity and no known fetal harm, although it crosses the placenta readily, and it is unbound in serum (19). It remains Food and Drug Administration Category B during pregnancy.
In one study involving 228 women with PCOS, three women were left out due to medical problems, 111 women were treated with CC plus metformin (metformin group) and 114 were allocated to CC plus placebo (placebo group). The ovulation rate in the metformin group was 64% compared with 72% in the placebo group.
Final Takeaways
Metformin remains the go-to first-line medication for PCOS with insulin resistance, thanks to decades of research, safety, and accessibility. Ozempic may be preferable for those with significant weight loss goals or if metformin is not tolerated or effective.
They can also prescribe metformin or clomiphene to address other hormonal issues that contribute to your condition. These prescriptions are often helpful if you are trying to get pregnant.

In conclusion, the present study indicates that in pregnancies in women with PCOS both the prevalence of pregnancy complications and the offspring sex ratio may be affected by the mode of conception.
