Thanks for posting your query at DoctorSpring.com
Before assisting you further, I would like to ask you for a few more details.
Since how long have you been trying for conception ?
What is the height and weight of your wife ?
Has she had any miscarriages ?
Why was IVF advised in the first place - any problems such as blocked tubes, problems in ovulation, fibroids, cysts etc ?
Where was the IVF carried out, and did she produce good quality eggs and embryos in the IVF ?
How long back was the IVF attempt carried out ?
Please write back with these details.
Looking forward to hearing from you.
