携带性连锁的疾病如杜兴氏肌营养不良和严重血友病的妇女,在生育小儿问题上,现时仍不能令人满意的选择:即可以选择不妊娠或下决心冒险生一个有1/2机会得病的孩子。现在通常用羊膜穿刺术和胎儿细胞培养来决定胎儿的性别,假如胎儿是男性。大多数孕妇选择中止妊娠。这样使父母承担失去50%正常男孩的机会而不可能有健康男孩。产前诊断的目的是为妊娠的血友病携带者提供有一个男性胎儿的新选择——即生育一个已知没有血友病的男孩。本文报告7例这样的病例。
Carriers of portability diseases such as Duchenne muscular dystrophy and severe hemophilia are still not satisfied with their options in childbirth: they can choose not to have pregnancy or are determined to take a risk of having a 1/2 Opportunity for sick children. Amniocentesis and fetal cell culture are now commonly used to determine the sex of the fetus, provided the fetus is male. Most pregnant women choose to suspend their pregnancy. This will make it impossible for parents to have healthy boys if they lose 50% of their normal boys’ chances. The purpose of prenatal diagnosis is to provide pregnant women with a hemophilia with a new option for a male fetus - that is, to give birth to a boy who is known to have no hemophilia. This article reports 7 such cases.
