What does DNA fragmentation indicate?

Sperm DNA fragmentation is a term used to denote abnormal genetic material within the sperm, which in turn may lead to male subfertility, IVF failure and miscarriage.

What happens if DNA is fragmented?

DNA damage, such as fragmentation and denaturation, can have adverse effects on fertilization and embryo development and can cause infertility [5].

Can you get pregnant with DNA fragmentation?

A DNA fragmentation index consistently >30% is associated with poorer fertility prognosis (increased risk of spontaneous abortion, failure to achieve pregnancy, longer time to successful pregnancy, and more IVF cycles).

Can you fix DNA fragmentation?

DNA fragmentation can be improved in most cases using nutritional and lifestyle changes.

What causes high sperm DNA damage?

Oxidative stress produces free radicals which attack the DNA molecule causing breaks in the DNA strands. Sperm DNA damage is often associated with underlying medical conditions (including: varicocele, infection or fever), or certain lifestyle choices (including: drinking, smoking or heat).

Does sperm DNA fragmentation cause birth defects?

Sperm DNA damage is often accompanied by numerical and structural chromosomal abnormalities of spermatozoa [28, 29], which can lead to birth defects or congenital malformation in newborns. In the present study, sperm DFI did not significantly affect birth defects of newborns among the three groups.

What causes DNA sperm fragmentation?

Sperm DNA fragmentation is associated with infections, cigarette smoking, drug use, exposure to environmental and occupational pollutants, advanced age, varicocele (enlarged veins inside the scrotum), illnesses with high fevers, elevated testicular temperature (laptop computers, hot tubs), chronic diseases such as …
