Does Diabetes effect fertility?

"How gestational diabetes can affect your baby
Gestational diabetes affects the mother in late pregnancy, after the baby's body has been formed, but while the baby is busy growing. Because of this, gestational diabetes does not cause the kinds of birth defects sometimes seen in babies whose mothers had diabetes before pregnancy.

However, untreated or poorly controlled gestational diabetes can hurt your baby. When you have gestational diabetes, your pancreas works overtime to produce insulin, but the insulin does not lower your blood glucose levels. Although insulin does not cross the placenta, glucose and other nutrients do. So extra blood glucose goes through the placenta, giving the baby high blood glucose levels. This causes the baby's pancreas to make extra insulin to get rid of the blood glucose. Since the baby is getting more energy than it needs to grow and develop, the extra energy is stored as fat.

This can lead to macrosomia, or a "fat" baby. Babies with macrosomia face health problems of their own, including damage to their shoulders during birth. Because of the extra insulin made by the baby's pancreas, newborns may have very low blood glucose levels at birth and are also at higher risk for breathing problems. Babies with excess insulin become children who are at risk for obesity and adults who are at risk for type 2 diabetes. "

However, if you are already diabetic and not a gestational diabetic.....
==============================...
Despite advances, babies born to women with diabetes, especially women with poor diabetes control, are still at greater risk for birth defects. High blood glucose levels and ketones (substances that in large amounts are poisonous to the body) pass through the placenta to the baby. These increase the chance of birth defects.

For this reason, good blood glucose control before you get pregnant is very important. Most women do not know they are pregnant until the baby has been growing for two to four weeks. During the first six weeks of pregnancy, the baby's organs are forming. Your blood glucose levels during these early weeks affect the baby's growing organs. High blood glucose levels can lead to birth defects.

Because these early weeks are so important to your baby, you need to plan your pregnancy. If your blood glucose levels are not in good control, work to bring your diabetes under control before getting pregnant. It is a good idea to be in good blood glucose control three to six months before you plan to get pregnant. You'll want to keep excellent blood glucose control during pregnancy, and after as well.

How do high blood glucose levels cause problems? When extra sugar is in your blood, the baby is "fed" extra sugar, too. All this excess sugar can make the baby too big and fat. Delivery of big babies is harder on mom and baby.

Because your baby is getting extra sugar, your baby's pancreas makes extra insulin. After birth, it's hard for the baby to stop putting out extra insulin. The baby must be watched, and treated if the blood glucose level drops too low.

For some reason, jaundice happens more often in babies of women with diabetes. Jaundice is a build-up of old red blood cells that the body can't process fast enough. This problem goes away rapidly with treatment. Source(s): From the American Diabetes Association

They have much more information than what I quoted above.

I don't have an "official" medical opinion on this-but my Sister/Brother & Dad all have/had it-and I have 13 nieces & nephews and 3 siblings....
No , not really, but if you are a pregnant diabetic it will impact your ability to carry this child to birth.

You will need a doc.

If you and your child have a different blood type for instance , this could prove a challenge.

Any Pregnant diabetic needs a doc from day one.

No reason you shouldn't have a flawless pregnancy and birth, but you need a doc that knows your history.

A diabetic should never attempt a pregnancy without a doc to guide her.
Not sure if it can cause a miscarriage.I haven't heard of any cases.It can affect fertility,but alot of people that have diabetes have had children.
