Fetal growth and the fetal origins hypothesis in twins--problems and perspectives.
Although there is substantial evidence from studies of singletons that small size at birth is linked with long-term adverse health effects, until recently little was known as to whether these associations extend to twins. A review of published studies suggests that at present there is little consistent evidence that birthsize in twins is associated with increased morbidity or morality. While, t...
متن کاملPlacentation in the African elephant, Loxodonta africana. IV. Growth and function of the fetal gonads.
The gonads, both ovaries and testes, of 44 elephant fetuses weighing 0.09-112 kg (6.1-21.3 months gestation) were examined grossly and histologically. As in equids, elephant fetal gonads undergo a phase of marked growth and enlargement during the second half of gestation, which is more pronounced in ovaries than testes due to growth and antrum formation of numerous follicles in the former. Stro...
متن کاملGender mix in twins and fetal growth, length of gestation and adult cancer risk.
This study evaluated the effect of gender mix (the gender combinations of twin pairs) on fetal growth and length of gestation, and reviewed the literature on the long-term effects of this altered fetal milieu on cancer risk. In singletons, it is well established that females weigh less than males at all gestations, averaging 125-135 g less at full term. This gender difference is generally belie...
متن کاملManagement of Fetal Growth Arrest in One of Dichorionic Twins: Three Cases and a Literature Review
Progressive fetal growth restriction (FGR) is often an indication for delivery. In dichorionic diamniotic (DD) twin pregnancy with growth restriction only affecting one fetus (selective fetal growth restriction: sFGR), the normal twin is also delivered prematurely. There is still not enough evidence about the optimal timing of delivery for DD twins with sFGR in relation to discordance and gesta...
متن کاملPerinatal outcomes in preterm growth-restricted twins: effects of gestational age and fetal condition.
OBJECTIVE To evaluate the perinatal outcome of intrauterine growth-restricted preterm twins and contribution of prematurity to morbidity and mortality. STUDY DESIGN A case-control study of 211 preterm twins: 108 growth-restricted twins matched with 103 normal growth twins of the same gestational age. Mortality and morbidity rates were compared between groups. RESULT Fetal and overall perina...
