In humans [4], multi-fetal pregnancy [5] occurs when a mother carries more than one fetus [6] during the pregnancy [7]. The most common multi-fetal pregnancy [5] is twins, but mothers have given birth to up to eight children (octuplets) from a single pregnancy [7]. Multiple fetuses can result from the release of multiple eggs or multiple ovulations, the splitting of a single fertilized egg [8],...

Early determination of pregnancy viability is essential for women at risk for experiencing ectopic pregnancy or spontaneous abortion. Several markers of pregnancy viability have been identified including serial human chorionic gonadotropin (hCG) monitoring and sonography, in addition to several less commonly available biochemical markers. An ideal test would be readily available, inexpensive an...

The epidemic of iatrogenic multiple births as a result of infertility treatment are responsible for an unacceptable high incidence of maternal, perinatal and childhood morbidity and mortality. Healthcare costs due to infertility therapy are too high and this may lead to social and political concern. The introduction of single embryo transfer (SET) was a real breakthrough, but was only accepted ...

BACKGROUND Women with multiple sclerosis (MS) are advised to discontinue interferon-beta therapy before trying to conceive. Unplanned pregnancies occur and risks related to exposure remain unclear. METHODS To determine pregnancy outcomes following interferon-beta therapy, we examined pregnancies from a global drug safety database containing individual case safety reports received in the post-...

thin ewes or very over-conditioned ewes and ewes carrying multiple pregnanciesare more likely to develop pregnancy toxemia (ketosis). pregnancy toxemia is a metabolic disorder characterized by hypoglycemia and hyperketonemia resulting from incapacity of the ewes to maintain adequate energy balance (usually in the last 5-6 weeks).available information about pregnancy toxemia focuses mainly on pa...
