I agree, but if it's your relatives, then it can be a big headache. I have a maternal aunt who underwent IVF decades back and she has 2 kids aged maybe 22 and 16 years old respectively. For the initial years, her own family members were talking behind their back, saying all the rubbish stuff, like "why the ivf baby has blue eyes, is it because the sperm comes from an ang moh?" (which is totally untrue), "the kid is so naughty, because he's not "natural" (again, it's rubbish)" blah blah blah, so I am not sure if the relatives ever told the children that they were via IVF and all the rubbish things and if yes, how the children felt. Kids tend to view other opinions very seriously and if it's negative, it may have an impact on their overall well-being.
It's just sad that some older folks see IVF children as different, lack of knowledge.
In fact, fertilization still depends on the egg n sperm alone. its up to them whether they fused and it's still not out of god's will. Implantation is also another natural factor so that's why success rate is not 100%.
The lab only help to give better environment for sperm to fuse with the egg. So to say, if it's out of god's will, why will there still be unsuccess???
I told my friends and relatives I've been tru so much and even though I'm lucky with twins pregnancy in first ivf but it was not a smooth process. don't care about folks cos their knowledge is limited.
