What was investigated and what was found?
Fresh and frozen-thawed testicular sperm were compared across 36 studies and 5,086 ICSI cycles. Some outcomes were associated with an advantage for fresh sperm.
Interpreting the findings
The designs of the included studies and patient selection limit causal conclusions.
How can you prepare for a consultation?
When discussing sperm freezing research, share any available laboratory information about sample origin, storage and previous thawing results. Ask which outcomes were compared using fresh and thawed sperm. Separating laboratory measures, such as motility or DNA integrity, from pregnancy and live-birth outcomes helps clarify what the publication means for your treatment discussion.
