Testicular sperm is healthy and can be used for ICSI. A percutaneous approach offers some advantages over the open approach, namely in the faster recovery and less pain.
The testis aspiration retrieval when used with ultrasound guidance is safe.
When combined with color flow doppler, retrieval rates approach the open technique.
Finally, this approach is good for the couple who is unsure about whether to proceed with ovarian stimulation prior to IVF-ICSI or to proceed with donor IUI.
I think this is the safest way. I will suggest this to my friend. Thanks for posting the informative article.
