thanks for your query.
You need to provide me with further details, as to why an ICSI
was necessary in the first place.
Also, the cause of stillbirth needs to be investigated.
You have to rule out genetic, chromosomal, autoimmune, infectious causes, uterine abnormalities and hormonal
imbalances - before planning a future pregnancy
If ICSI was advised and carried out in the first case, then chances are high that you would require ICSI and IVF again to conceive.
The chances of natural conception after 12 years of married life and 4 failed ICSI cycles are quite low .
Please consult an Infertility
specialist and do not waste more time.
take care and wish you luck .
