lets say IVF alone. with medical advances improving exponentially, the success rates increases. the highest average success rates are no more than 60%, with the average are about 30-40%. Any centers that claims higher are likely using falsified advertisement /bias data.
Success rates are affected by various factors, tends to be higher for younger couples, while lower for elderly couples. It is also affected by the current health status of the male and female.

Though u r right, the cost is about RM15k+ for the first time. But subsequent retry usually cost less, again, due to several factors. eg, (additional spare eggs were harvest from the first attempt).

I believe most couple find the time consumption, and going thru repeated failures most depressing. There are alot of centers for Reproductive Medicine specialist today. Its best to pick one thats reliable.

IVF does come with failure rates as i mentioned. These failures includes fail to conceive or miscarriage along the way.
(PS: doctors don't use the word "healthy". "No known medical illness", is a preferred term)
IVF is expected to have failure rates. It is more of a .... "push" or Assisted conceptions as they called it. If a fail to conceive or a miscarriage occurs, its usually bcoz that pregnancy was not meant to be (usually due to bad genetic combination of the embryo). It is just by chance. (FYI about 50% of natural conception auto aborts without the women realizing their pregnant for the same reasons. Most women noticed a slight late/heavier periods.)

A couple going for assisted conception used to be stigmatized and alone. But today, fortunately we have this forum and community to help one another.
Dont worry too much about it. Looking at your very own pair of eyes looking back at you.... priceless.
I wish you all the best. perhaps one day, ull return here to share and help another couple in the future.
