Monozygotic twinning: is it related to apoptosis in the embryo?
The advent of prolonged in-vitro preimplantation embryo culture using sequential culture media (Gardner et al., 1998) has permitted many IVF laboratories to successfully adopt blastocyst transfer. Unfortunately, an unexpected side effect of this success has seen a small but significant appearance of monozygotic twinning. This has now been described by several authors (Peramo et al. Curiously en...
متن کاملMonozygotic Twinning in Mice.
Because of the predominance of multiple ovulation in mice, it has been generally accepted that evidence for monozygotic twinning would be difficult to obtain. The two attempts that have been made have failed to find any evidence for twins surviving birth at a measurable rate. In Fisher and Mather's (I936) sevenfold backcross experiment there is no evidence of twinning at all. In each of Bateman...
متن کاملHuman zona pellucida micromanipulation and monozygotic twinning frequency after IVF.
To assess the association of zona pellucida micromanipulation and subsequent development of monozygotic twins, cases of assisted embryo hatching (AH) and intracytoplasmic sperm injection (ICSI) were identified and related to treatment type, implantation and zygosity data. Embryology records from all patients undergoing in-vitro fertilization (IVF) at this centre from January 1995 to March 1998 ...
متن کاملHeterotopic pregnancy after a single embryo transfer
Heterotopic pregnancy is a rare and life-threatening condition which is defined as coexistent intrauterine and ectopic gestation. The risk of ectopic and heterotopic pregnancy is increasing due to the increased risk of multiple pregnancies with the aid of assisted reproductive technologies. However, it hardly happens in the setting of single embryo transfer, since single embryo transfer signifi...
متن کاملThe Comparison Between the Pregnancy Outcome after Easy Embryo Transfer and Difficult Embryo Transfer
Background: The role of embryo transfer (ET) in the success of in vitro fertilization/intra cytoplasmic sperm injection treatment is not well understood. In the present study we classified ET technique as difficult and easy types according to certain strict criteria, and compared the pregnancy outcome of the two ET types. Methods: This study was performed retrospectively on 295 infertile patien...
