Fetus and annexes

Ovarian pregnancy is a rare form of ectopic pregnancy but it is the most common type of nontubal ectopic pregnancy. Many times it is operated with a misdiagnosis of ruptured tubal ectopic pregnancy or hemorrhagic corpus luteum.
Ectopic pregnancy is an important health problem and accounts for 10% of all maternal mortality. Incidence of ovarian pregnancy in natural conception vary from one in 7,000 to one in 40,000 deliveries and accounts for <3% of all ectopic pregnancies.

Environmental effects on the materno-foetal interaction determine birth outcomes that predict health over the lifespan. Thus, maternal undernutrition or stress associate with low birth weight, leading to an increased risk of metabolic and cardiovascular illness in the offspring.
