What is a horned uterus?
A bicornuate uterus is a congenital abnormality, which means it’s something a woman is born with. It happens when a baby girl’s uterus doesn’t develop normally in the womb. Special ducts only partially fuse together, which leads to separation of the two upper parts, or horns, of the uterus.
What birth defects are caused by bicornuate uterus?
Offspring of mothers with a bicornuate uterus had a risk for congenital defects four times higher than infants born to women with a normal uterus. The risk was statistically significant for some specific defects such as nasal hypoplasia, omphalocele, limb deficiencies, teratomas, and acardia-anencephaly.
Which type of uterus is best for pregnancy?

What week do most miscarriages happen?
Most miscarriages happen in the first trimester before the 12th week of pregnancy. Miscarriage in the second trimester (between 13 and 19 weeks) happens in 1 to 5 in 100 (1 to 5 percent) pregnancies. As many as half of all pregnancies may end in miscarriage.

- Smoking, alcohol and illicit drugs.
- Weight.

How does the shape of the uterus affect fertility?
A woman may have a malformed or poorly shaped uterus as a result of a genetic issue. Examples of this include T-shaped uterus, a bicornuate uterus, and uterine septum. These uterine malformations may make it more difficult to become pregnant and can potentially increase risk of miscarriage or premature birth.
Can bicornuate uterus carry twins?
Having a twin pregnancy in a patient with a bicornuate uterus (uterus bicornis unicollis) is rare, especially if it is a spontaneous conception. Case: A 40-year-old primigravid woman conceived a twin dichorionic diamniotic pregnancy after three years of primary infertility.
Why do most miscarriages happen at 7 weeks?
Common First Trimester Miscarriages
Most miscarriages happen between 6 and 8 weeks gestation. We know that most of these occur due to a major genetic abnormality in the fetus. The sperm and the egg (which are known as gametes) each contain half the genetic material necessary for a complete person.

Why do I keep miscarrying at 8 weeks?
Recurrent early miscarriages (within the first trimester) are most commonly due to genetic or chromosomal problems of the embryo, with 50-80% of spontaneous losses having abnormal chromosomal number. Structural problems of the uterus can also play a role in early miscarriage.
