There is some suggestion that birth defects are increased with the use of IVF in general, and ICSI specifically, though different studies show contradictory results. In a summary position paper, the Practice Committee of the American Society of Reproductive Medicine has said it considers ICSI safe and effective therapy for male factor ...
The majority of IVF-conceived infants do not have birth defects. [13] However, some studies have suggested that assisted reproductive technology is associated with an increased risk of birth defects. [14] [15] Artificial reproductive technology is becoming more available. Early studies suggest that there could be an increased risk for medical ...
The first human birth of oocyte cryopreservation was reported in 1986. [ 1 ] According to a review including 936 live births between 1986 and 2008 in the United States obtained from 58 cryopreservation studies, the incidence of major structural congenital anomalies was 1.3%, or no difference compared to the results of naturally conceived ...
High-quality sperms are injected into the egg for fertilization, it is an advanced version of ICSI. A high powered microscope is used to pick out and the best sperm cells which are then used in a traditional ICSI protocol. In ICSI a magnification of x400 is used, while in IMSI an amplification of x6000 to x10,000 is used, increasing the ...
[96] Parental factors included known independent risks for birth defects such as maternal age, smoking status, etc. Multivariate correction did not remove the significance of the association of birth defects and ICSI (corrected odds ratio 1.57), although the authors speculate that underlying male infertility factors (which would be associated ...
In current state of the art, early embryos having undergone cryopreservation implant at the same rate as equivalent fresh counterparts. [2] The outcome from using cryopreserved embryos has uniformly been positive with no increase in birth defects or development abnormalities, [3] [8] also between fresh versus frozen eggs used for intracytoplasmic sperm injection (ICSI). [9]
It is abnormally expressed in fetuses of both IVF and ICSI, which may contribute to the increase risk of birth defects in these ART. [7] This gene encodes a member of the annexin family. Members of this calcium-dependent phospholipid-binding protein family play a role in the regulation of cellular growth and in signal transduction pathways.
Gianpiero D. Palermo is the developer of the revolutionary procedure known as intracytoplasmic sperm injection (ICSI) in 1991, [1] [2] which is able to overcome male infertility in many cases. Since 1993, he has been the Director of Assisted Fertilization and Andrology at The Center for Reproductive Medicine and Infertility and has led the ICSI ...
