IMSI for severe teratozoospermia: does magnification help?

What was investigated and what was found?

In the double-blind trial, high-magnification selection did not significantly improve pregnancy or live birth over standard ICSI. Selected-sperm DNA damage measures were also similar.

Interpreting the findings

Results apply to the enrolled population and tested protocols; they are not a personal success prediction.

How can you prepare for a consultation?

Bring semen analyses, any DNA-fragmentation or urology/andrology reports, and previous fertilization results. Findings from both partners should guide discussion of IVF or ICSI planning.
