[quote=pattiewrites] Twin pregnancies usually turn out just fine. [quote]
This is only half true. Less than 10% of women carry twins full term. Twins don't grow the same in utero as singletons do and so even twins born full term are more likely to be low birth weight babies with the various associated health risks. Twins are twice as susceptible to RSV, developmental disorders and delays and I haven't even started talking about the risks to mom. (But I will concede that many twins do grow and are just fine
I wouldn't necessarily consider it unethical to implant two embryos for women who are more likely to go full term (which really in a twin pg is very hard to predict. . .even very healthy women with healthy pg are high risk for preterm labor) but I hate the idea that it's considered an 'easy two for one deal'. It is not two for one and it's not easy--I just don't think people get it.
I guess the existential question here is when is it considered to do 'harm' to the mom and babies? Certainly creating a scenario where the babies will be premature should be considered 'harmful'. Putting a mother at risk for gestational diabetes, severe diastasis requiring surgery, heart problems, etc. should be considered 'harmful' as well. Regardless of the patient's wishes. JMHO
