multiple gestation

The presence of two or more embryos in the uterus. Twin and higher gestations have greatly increased in the past two decades due to the increased use of ovulation induction agents and assisted reproduction technologies. Currently 3% of all births are multiple gestations. When twins are diagnosed by ultrasound early in the first trimester, in about half of these cases one twin will silently abort, and this may or may not be accompanied by bleeding. This phenomenon has been termed the vanishing twin. The incidence of birth defects in each fetus of a twin pregnancy is twice that in singular pregnancies. Triplet, quadruplet, and higher gestation pregnancies are usually a result of commonly used fertility drugs. Multiple gestations are associated with an increased risk of perinatal morbidity and mortality.

From this perspective, selective termination is not so much an extension of women's reproductive choice as it is the extension of control over women's reproductive capacity-through the use of fertility drugs, GIFT, and IVF as "solutions" to infertility that often result, when successful, in multiple gestations; through the provision of a technology, selective termination, to respond to multiple gestation that may create much of the same ambivalence for women as is generated by abortion; and finally through the imposition of limitations on women's access to the procedure.
