Effect On Reproduction
Pregnancies in a bicornuate uterus are usually considered high-risk and require extra monitoring because of association with poor reproduction potential.
A bicornuate uterus is associated with increased adverse reproductive outcomes like:
- Recurrent pregnancy loss: the reproductive potential of a bicornuate uterus is usually measured by live birth rate (also called fetal survival rate).
- Preterm birth: with a 15 to 25% rate of preterm delivery. The reason that a pregnancy may not reach full-term in a bicornuate uterus often happens when the baby begins to grow in either of the protrusions at the top. A short cervical length seems to be a good predicter of preterm delivery in women with a bicornuate uterus.
- Malpresentation (breech birth or transverse presentation): a breech presentation occurs in 40-50% pregnancies with a partial bicornuate uterus and not at all (0%) in a complete bicornuate uterus.
- Deformity: Offspring of mothers with a bicornuate uterus are at high risk for "deformities and disruptions" and "malformations."
Previously, a bicornuate uterus was thought to be associated with infertility, but recent studies have not confirmed such an association.

Famous quotes containing the words effect on, effect and/or reproduction:
“Movies are one of the bad habits that corrupted our century. Of their many sins, I offer as the worst their effect on the intellectual side of the nation. It is chiefly from that viewpoint I write of them—as an eruption of trash that has lamed the American mind and retarded Americans from becoming a cultured people.”
—Ben Hecht (1893–1964)
“The want of an international Copy-Right Law, by rendering it nearly impossible to obtain anything from the booksellers in the way of remuneration for literary labor, has had the effect of forcing many of our very best writers into the service of the Magazines and Reviews.”
—Edgar Allan Poe (1809–1849)
“As the twentieth century ends, commerce and culture are coming closer together. The distinction between life and art has been eroded by fifty years of enhanced communications, ever-improving reproduction technologies and increasing wealth.”
—Stephen Bayley (b. 1951)
