WHY ? Congenital anomaly - IVF ? - Maternal DM ? - Chromosomal ?
Discussion Assisted reproductive technology and perinatal risk
Louise brown in 1978 - First ART baby - Oldham hospital
In Vitro Fertilization Step 1: Control Ovarian Hyperstimulation (COH) Step 2: Egg Retrieval Step 3: Fertilization Step 4: Embryo Culture & Embryo Quality Step 5: Embryo transfer Assisted reproductive technologies (ART)代表所有在體外對oocyte做的事情。 其中,IVF是ART中的老祖宗,也是現今最常用的一種方式。 三步驟: 排蛋抓蛋受精蛋 排蛋Monitoring and stimulating a woman's ovulatory process 抓蛋Removing ovum or ova from the woman's ovaries 受精蛋Letting sperm fertilize them in a liquid in a laboratory.
In Vitro Fertilization Factor which believed increase perinatal risk underlying causes of infertility - aspects of the ART procedures the medications used, culture media composition, length of time in culture, freezing and thawing of embryos, altered hormonal environment at the time of implantation, the manipulation of gametes and embryos or a combination of these.
Introduction Infertility 10-15% over world (50% female, 30% male, 20% unknown) ART induced perinatal risk Preterm birth LBW, SGA birth Birth defect Vertical transmission of genetic diseases ?
ART and Preterm birth Statistically significant about 20% increase in the relative risk of preterm birth in IVF twins Estimated two-fold increased risk of preterm birth in IVF singletons Reason ?

ART and LBW birth Both singleton and twin IVF pregnancies demonstrate an increased risk of low birth weight compared with naturally conceived (RR about 1.5) the relative risk of babies being SGA is also increased about 40–60% McDonald SD, Han Z, Mulla S, Murphy KE, Beyene J, Ohlsson A.

ART and Birth defect Between 2% and 3% of all infants are diagnosed with a congenital anomaly soon after birth. IVF is associated with a 30–40% increased risk of major congenital anomalies compared with natural conceptions. pre-auricular tags, tongue tie, undescended testicles, unstable hips, single umbilical artery (www.eurocat-network.eu) Hansen M, Bower C, Milne E, de Klerk N, Kurinczuk JJ.

ART and Vertical transmission of genetic diseases Microdeletions of the long arm of the Y chromosome (Yq), in particular the AZF region, can also cause spermatogenic failure and either oligo- or azoospermia ART imprinting syndrome ??? Beckwith-Wiedemann syndrome (BWS), Angelman syndrome (AS) and, more recently, maternal hypomethylation syndrome 本科張旭陽、蔡孟穎醫師(1997年)曾針對68位南台灣的這些罹患無精子或精子稀少症的男性分析,發現有6位( 9%)的確有這方面基因的缺陷。 Amor DJ, Halliday J.

Long-term outcomes for children ART parents - Expressed greater warmth towards their child, - interacted more with their child - less stress associated with parenting Golombok S1, Brewaeys A, Cook R, Giavazzi MT, The European study of assisted reproduction families: family functioning and child development.

Take home message IVF pregnancies are at increased risk of adverse perinatal outcomes, it is also the case that the majority of the children born following IVF will have a normal outcome Recommend complete pre-natal examination for IVF birth
