In vitro fertilization and embryo transfer. Present and future.

In Vitro Fertilization and Embryo Transfer

macrophages" is discussed in the third symposium. Most studies in this section have employed the methodology of DNA labeling, using tritiated thymidine (3H-Tdr) to ascertain whether microglia are related to blood monocytes (as one contributor contends most CNS macrophages are), or whether they represented a "third" glial cell line. Other articles attempt to quantitate neural synapses, to elabor...

In vitro fertilization and embryo transfer.

In vitro fertilization is one of the newest approaches to infertility. Opportunities for nurses in IVF involve teaching couples about physiology, providing technical assistance and care, and counseling about the medical and emotional aspects of the program. Many times the nurse serves as the primary support person for couples and as their advocate with other team members.

The Past, Present, and Future of Embryo Selection in In Vitro Fertilization

Assisted reproductive technology (ART) has been recognized for its success in treating infertility, a condition that affects 15 percent of couples in the United States. The most popular option is in vitro fertilization (IVF), which relies on embryo culture, selection, and transfer for implantation, with the ultimate aim of pregnancy. Previous embryo selection methods relied on morphological fac...

Heterotopic pregnancy after in vitro fertilization and embryo transfer.

We have presented a second case of heterotopic pregnancy after IVF-ET. The most likely cause is direct extrusion of embryos through the tubal ostia by the hydrostatic pressure associated with ET. The diagnosis of ectopic pregnancy must be suspected clinically and not ruled out on the sonographic demonstration of an intrauterine pregnancy. Early diagnosis is essential for the prevention of signi...
