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.

Hmm.. there are numerous Reproductive medicine in Malaysia now. Truth is its hard to tell who are the best. But picking one thats reliable should be ok.
I believe scrolling the forum, ull notice a few recommendation.

In malaysia, there is no restriction yet as whom(doctor) can treat infertility.
My advise is to pick on thats a fully registered reproductive specialist (A gynaecologist whom have further sub-specialist in reproductive medicine).

Perhaps you could look into Asst Prof Dr Tee Swi Peng.

Dr Tee Swi Peng is one of the fully registered Reproductive Medicine Specialist in Malaysia. When reproductive medicine became on official specialization in Malaysia, he was among the pioneer whom were direct recognized by the ministry and NSR.

He is a lecturer UTAR as a clinical-assistant Professor and also run his own private practice in MetroIVF.

Statistically his success rate is among the highest in Malaysia which is y he is recommended.

He has appeared in several public talks and interviews and has appeared several times in TV and radios in Malaysia. We might be able to still find his talks and seminar recordings on youtube.

You could try search MetroIVF facebook or email via their official website.

Probably none of my business to ask why are u trying to get ur ex wife pregnant and emailing on her behalf, but

Malaysia have set up several regulations in reproductive medicine. I am not entirely familiar but there are criteria before allowing an individual to be pregnant via artificial methods,eg, marriage/capability of having a baby, age limit, egg donors and etc. Its best to consult the a reproductive medicine specialist in malaysia.
Some of ur questions are medical related questions and some questions could not be reply by the sales management inquiry. Should you need to seek a doctors opinion, unfortunately u are required to be physically present there.

Every physician has their own protocol and techniques. Cost has always been an issue. IVF has a more guaranteed success as it relies on less factors (eg, tubal blockage).
Some specialist prefer to jump in straight for IVF, rather than spending more of patients money and time running procedures of to what caused the infertility, which may not even change the outcome.
Some would try for IUI which is less costly.
Block tubes can be an acquired or congenital(birth). Pelvic inflammatory disease are notorious and often asymptomatic can cause tube narrowing later in life.

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.
