Changes in DNA fragmentation during sperm preparation for intracytoplasmic sperm injection over time

Friday, June 28, 2013
We assessed sperm DNA fragmentation (TUNEL) at different time periods before ICSI, and found DNA fragmentation significantly decreased after gradient and samples with TUNEL >20% were more susceptible to a significant increase over time.

Frozen-thawed spermatozoa from oligozoospermic ejaculates are susceptible to in situ DNA fragmentation in PVP-based sperm immobilization medium

Friday, June 8, 2012
Polyvinylpyrrolidone-based medium can induce sperm DNA fragmentation during intracytoplasmic sperm injection, and frozen-thawed sperm from oligozoospermic ejaculates are more susceptible to in situ DNA fragmentation.
