胚胎植入前遗传学诊断(PGD)

  植入前遗传学诊断(PGD)对于有遗传性疾病传染给孩子的夫妇来说是一个很好的选择。PGD 允许医生和胚胎学家根据其遗传组成确定胚胎是否携带特定疾病。
 
  PGD用于筛查染色体的异常数量,染色体的破损或损坏以及其他异常情况。
 
  PGD可用于筛选许多条件,包括:
 
  唐氏综合症
 
  21三体综合症
 
  泰萨克斯病
 
  血友病A和B.
 
  戈谢病,镰状细胞贫血
 
  PGD针对最常见的染色体问题在女性胚胎上进行,使医生和夫妇能够确定哪些胚胎最有可能导致健康的持续妊娠。另外,对于由于不明原因导致IVF周期失败的夫妇,植入前遗传诊断可以在确定失败原因时提供重要信息。
 
  PGD也可用于 性别选择。
 
  Preimplantation Genetic Diagnosis (PGD)
 
  Preimplantation Genetic Diagnosis (PGD) is a wonderful option for couples who are at risk of transmitting a genetic disease to their children. PGD allows the physician and embryologist to determine if an embryo carries a specific disease based on its genetic composition.
 
  PGD is used to screen for abnormal numbers of chromosomes, broken or damaged chromosomes, and other anomalies.
 
  PGD can be used to screen for many conditions including:
 
  Down Syndrome
 
  Trisomy 21
 
  Tay Sachs Disease
 
  hemophilia A and B
 
  Gaucher's Disease, Sickle Cell Anemia
 
  PGD performed on a woman's embryos for the most common chromosomal problems enables the physician and couple to determine which embryos will most likely result in a healthy, ongoing pregnancy. Additionally, for couples that have failed IVF cycles for unexplained reasons, preimplantation genetic diagnosis may provide important information in the determination of the cause(s) of the failures.
 
  PGD can also be used for gender selection.
