Human embryo is a human embryo, not a pre‐embryo
International Journal of Gynecology & Obstetrics, 2000Objectives: The aim of the study was to investigate the scientific evidence underlying the progressive introduction of the new term “preembryo” in the literature concerning in vitro fertilization and applied preimplantation genetics. Study Methods: Four approaches to the study of the developing human embryo were considered: genomics, DNA expression ...

Residual embryos in failed embryo transfer
Fertility and Sterility, 1986One hundred thirteen embryo transfers (ETs) were performed in an in vitro fertilization and ET program of which residual or extruded embryos were found in 17 transfers (15%). Residual or extruded embryos are those embryos found outside the uterine cavity, either at the cervical os, on the vaginal speculum, or remaining in the catheter after an ET ...

Embryo transfer is a critical step in the overall success of in vitro fertilization (IVF). Despite its apparent simplicity, it is an integral part of the IVF cycle that can be difficult to teach and perform well. In this chapter we describe the procedure of embryo transfer and discuss various modifications that have been evaluated in an effort to ...

Cryopreservation stands as an ongoing evolution in the field of assisted reproductive technologies. Face with increasing numbers of fertilized oocytes and early embryos, cryopreservation avails the ART program of a useful means to preserve embryos for future use without exposing patients to the risks of multiple pregnancies.

AbstractA number of viruses are capable of producing intrauterine infection and damage. Both rubella and cytomegalovirus may cause malformations. For rubella the most frequent defects are those involving the heart, eyes, brain, and ears. With cytomegalovirus, children may be microcephalic, small, and mentally retarded.

In order to determine the human rights of the embryo, we must first determine whether or not it is a person. Certainly, it does not look like a person when its life begins, or in the first stages of it existence. But in its genetic makeup, it has the active potency that enables it to develop the characteristics that we associate with personhood.

Genetica, 1968
In fossil material from two welis from Java, one section from East Java and two sections from Madura, specimens belonging to the extinet genusLepidocyclina (Foraminifera) were examined. Attention was paid to the embryonic part of the megalospheric forms exclusively.

Annals of the New York Academy of Sciences, 1985
Success and failure of embryo transfer involves at least five major variables: (1) technique, (2) what is transferred, (3) when transfer occurs, (4) endometrial status at transfer, and (5) endometrial support subsequent to transfer. Because of these and other variables associated with programs of in vitro fertilization, it is quite impossible to ...

AbstractIn Italy, the seat of the Vatican, the problem of the “rights of the embryo” has been particularly felt and has caused bitter debate between laymen and clergy. The disagreement has focused primarily on the definition of “person,”“individual,” and the “beginning of life.” Catholics, for the most part, have contested the concept of the “pre ...
