Ectopic pregnancy and spontaneous abortions following in-vitro fertilization and embryo transfer. 1985

S Lindenberg, and J G Lauritsen, and S Lenz

In-vitro fertilization and embryo transfer was performed in 25 patients with diseased oviducts. Three pregnancies were achieved, but all ended in early abortion. One patient had ectopic pregnancy, one spontaneous abortion having a severe autosomal chromosome abnormality, and one had a rise in serum hCG but vaginal bleeding started 18 days after embryo transfer. We conclude that repeated ultrasonic examinations of all pregnancies following in-vitro fertilization and embryo transfer is recommendable until intra-uterine implantation has been confirmed and that amniocentesis should be offered to all these patients.

D011247	Pregnancy	The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.	Gestation,Pregnancies
D011274	Pregnancy, Tubal	The most common (>96%) type of ectopic pregnancy in which the extrauterine EMBRYO IMPLANTATION occurs in the FALLOPIAN TUBE, usually in the ampullary region where FERTILIZATION takes place.	Tubal Pregnancy,Pregnancies, Tubal,Tubal Pregnancies
D002905	Chromosomes, Human, 4-5	The large, submetacentric human chromosomes, called group B in the human chromosome classification. This group consists of chromosome pairs 4 and 5.	Chromosomes B,Group B Chromosomes,Chromosome, Group B,Chromosomes, Group B,Group B Chromosome
D004624	Embryo Transfer	The transfer of mammalian embryos from an in vivo or in vitro environment to a suitable host to improve pregnancy or gestational outcome in human or animal. In human fertility treatment programs, preimplantation embryos ranging from the 4-cell stage to the blastocyst stage are transferred to the uterine cavity between 3-5 days after FERTILIZATION IN VITRO.
