Task: Answer Verification
Input (English): Question: Does semen treatment with progesterone and/or acetyl-L-carnitine improve sperm motility or membrane damage after cryopreservation-thawing?
Answer: Neither progesterone nor acetyl-L-carnitine seemed to prevent cryodamage assessed by motility changes or membrane integrity in human spermatozoa of subfertile men. Annexin V binding, a reflection of membrane translocation of phosphatidylserine, provided more distinct information about postfreezing membrane integrity changes than eosin-Y staining.
Output (English): no
