The risk of oocyte damage by the ICSI procedure is low in humans and is due to both the skill of the person performing the injection procedure and the quality of the gametes used during the procedure .The embryologist performing ICSI procedure is a significant predictor of fertilization, and laboratory conditions (i.e. incubators, culture of oocytes individually versus grouped) do Cited by: 1.

Factors affecting results of ICSI. Spermatozoal factors. Nagy et al. reviewed the effect of spermatozoal factors on results of ICSI in microinjection cycles. Despite no normal forms in a semen preparation, virtual azoospermia or essentially no motile sperm in the ejaculate, pregnancy could still be by: Acute = a single dose has less chance of affecting the embryo unless it is given at a critical period for a particular organ or set of organs Chronic = the benefits of the treatment for the mother must be weighed against the risks for the embryo.

Factors affecting risks of congenital malformations: reports from the collaborative perinatal project. Although mechanical factors have been implicated in the genesis of congenital malformations for centuries, only in more recent years has it been possible to relate specific malformations to mechanical causes.

There have been amazing advances in embryology, teratology, reproductive biology, genetics, and epidemiology in the past 50 years that have provided scientists and clinicians with a better perspective on the causes of congenital malformations.

Factors Affecting Risks of Congenital Malformations. By Chin S. Chung, Ph.D. and Ntinos C. Myrianthopoulos, Ph.D. Editor: Daniel Bergsma, M.D. Birth Defects: Original. INTRODUCTION. Congenital heart disease (CHD) is the leading cause of birth defects, and accounts for more deaths in the first year of life than any other condition when infectious etiologies are excluded .With an incidence ranging from 19 to 75 per one thousand live births and present in an even greater proportion of miscarriages, CHD is an important cause of childhood Cited by: The distinction should be made clear between a diagnostic and a screening test.
The former confirms or refutes the existence of an actual anomaly in a fetus believed to be at increased risk, whereas the latter identifies an increased likelihood of a fetal abnormality in an apparently normal pregnancy.
5 The value of a screening test is outlined by the fact that most congenital. Oligohydramnios (deficient amniotic fluid) often accompanies congenital malformations of the fetal urinary tract and severe fetal growth restriction. This study has attempted to assess the burden imposed by congenital anomalies in terms of postnatal mortality and morbidity, which were in turn used to classify anomalies as severe and mild types.
Factors studied were postnatal mortality through age 7 years and morbidity, as measured by neurologic and psychologic abnormalities, histories of major surgery, prolonged. Follow Chin Sik Chung and explore their bibliography from 's Chin Sik Chung Author Page.
• Genetic factors: Such factors cause nearly 40% of childhood hearing loss. It has been shown that hearing loss is much more frequent in children born of consanguineous marriages or those unions between two individuals who are closely related.
Congenital malformations of the ear and the hearing nerve,File Size: 1MB. Birth defects, congenital anomalies, and congenital malformations (defects) are all used interchangeably to describe the consequences of abnormal development. A birth defect is any defect present at birth regardless of whether it was detected at the time of birth.
The authors examined first-year mortality and risk factors for mortality among infants with major congenital malformations.|Infants with major congenital malformations born from to were identified from a statewide population-based congenita Cited by: The impact of genetic variability on embryogenesis and fetus development established medical genetics as essential for the prevention of congenital anomalies, early detection and appropriate management.
Advances in ultrasonography equipment and technique allow early detection of many congenital malformations. In addition, genetic testing can be performed in a prenatal Author: Mihaela Amelia Dobrescu, Florin Burada, Mihai Gabriel Cucu, AncaLelia Riza, Gratiela Chelu, Razvan M. Anorectal malformations (ARMS) are also known as imperforate anus (IA).
This is an "umbrella term" for a group of birth defects which affect the anorectal area. During a normal bowel movement, solid waste passes from the colon (large intestine) to the rectum (the final section the colon) and through the anus.
Teratology is the science of studying and investigating the birth defects and their etiologies. At birth, the incidence of the congenital malformations amounts to %, however by the elapse of the first neonatal year the incidence rises to about 5%.

CHDs occur as a result of abnormal embryogenesis of the heart. Congenital heart diseases are associated with significant mortality and morbidity. The damage of the heart is irreversible due to a lack of regeneration potential, and usually, the .
