Discordance between human sperm quality and telomere length following differential gradient separation/swim-up
BackgroundStrong evidence has suggested an important role of telomeres in meiosis, fertilization, and embryo development.
PurposeTo determine if...

Second ejaculation produces good quality sperm and blastocyst and decreases the rate of unexpected ICSI cycle: a propensity score-matched analysis
BackgroundSecond ejaculation can influence sperm quality which may define the first-line treatment. The purpose of this study was to evaluate the...

Molecular Chaperone HSPA2 Distribution During Hyaluronic Acid Selection in Human Sperm
During fertilization, sperm hyaluronidase activity is essential for spermatozoa to successfully penetrate the hyaluronic acid-enriched extracellular...
-
Sperm selection during ICSI treatments reduces single- but not double-strand DNA break values compared to the semen sample
PurposeTo detect a possible bias in sperm DNA fragmentation (SDF) testing when performed on semen samples or on those few spermatozoa selected for...

Variables and protocols of the tethered swimming method: a systematic review
BackgroundThe tethered swimming (TS) is an ergometer where swimming is simulated in an ecological environment, commonly used for assessing force in...

Chronically high stress hormone levels dysregulate sperm long noncoding RNAs and their embryonic microinjection alters development and affective behaviours
Previous studies on paternal epigenetic inheritance have shown that sperm RNAs play a role in this type of inheritance. The microinjection of sperm...
