Metformin and fertility -
Obese women diagnosed with PCOS are usually hyperinsulinemic, that is, they have increased levels of insulin and androgens male hormones in their body.
Metformin helps to decrease the insulin resistance in PCOS patients. Metformin may also decrease the risk of miscarriage associated with PCOS. Metformin makes the body cells sensitive to insulin. It also helps to diminish the excess production of androgen by the ovaries to a great extent.
Metformin is used as a hormone balancing drug to help resume the ovulation process in some PCOS women. Sometimes, fertility specialists prescribe Metformin along with Ovulation Induction drugs like Clomiphene or Letoval and Follicle Stimulating Hormone FSH for inducing ovulation.
Metformin has numerous actions on the body and the main is the suppression of the production of endogenous glucose by the liver. Metformin keeps the insulin production in the body at bay and improves its effectiveness.

However, the authors noted that the evidence was low-quality and more research is needed. A study showed that PCOS patients had fewer late miscarriages and premature births if they took metformin. PCOS raises the risk of complications such as preterm birth and miscarriage.
Out of women who took metformin, only 9 experienced miscarriage or preterm birth. This is compared to 23 out of women who had complications and did not take metformin. Ovarian Hyperstimulation Syndrome OHSS is a complication people can experience while taking injectable hormone medication.
It can cause painful and swelled ovaries. OHSS is more common in people with PCOS. For this reason, the drug may be prescribed to pregnant patients who are classified as overweight or obese. The drug may reduce glucose production and improve glucose uptake. Some believe that this may improve the overall metabolism, which reduces the risk of negative pregnancy outcomes associated with obesity.
More research is needed to understand how the drug affects weight. Some people are resistant to the fertility drug clomiphene. When looking at the documented benefits as a whole, it appears metformin may work—but only in certain cases.
Research suggests that metformin for fertility is only effective for specific people. This includes people with PCOS who are:. For this reason, some researchers suggest that patients continue taking metformin through the first trimester.

Under certain conditions, too much metformin can cause lactic acidosis. The symptoms of lactic acidosis are severe and quick to appear, and usually occur when other health problems not related to the medicine are present and are very severe, such as a heart attack or kidney failure.
Metformin does have some side effects, including nausea, diarrhea and excess gas. These generally occur only while the body is first getting used to the medication, and then they subside.

Commentary: In Ferhility Exposure Senior athlete nutrition Enhanced immune support Reduces fertolity Fertility of Male Offspring in Metforin. Metformin Metformin and fertility a fertiligy used for the treatment Immune system defense type 2 diabetes znd disorders associated with insulin resistance. Senior athlete nutrition is also used in the treatment of pregnancy disorders such as gestational diabetes. However, the consequences of foetal exposure to metformin on the fertility of exposed offspring remain poorly documented. In this study, we investigated the effect of in utero metformin exposure on the fertility of female and male offspring. We observed that metformin is detectable in the blood of the mother and in amniotic fluid and blood of the umbilical cord. Metformin was not measurable in any tissues of the embryo, including the gonads.
