I know that if man with AS genotype marries to a woman with AS genotype, they have 25% chances of giving birth to a child with SS genotype, for every pregnancy. I also know that one can determine the foetus genotype and abort. I also know that this can be determined through Aminocintesis.

My question now are:
1. How reliable and safe is this test? can the woman risk losing her life in the process? How expensive is the test?
2. Is there any other means giving birth to an SS child can avoided, after two AS couples have gotten married?
3. Can any of these tests be done in Nigeria?
4. Is there any major risk involved in abortion, medically? If yes where?

I have AS genotype and just got married to a woman with AS genotype. Please I need your answers, especially medical practitioners.
