Antioxidants have long been the sole treatment option for men with high levels of sperm DNA fragmentation. A new study has shown that another treatment option may be helpful too - daily ejaculation - which has been shown to significantly decrease the percentage of sperm with DNA damage.
In one study, daily ejaculation for seven days was enough to make a significant difference to sperm quality. The study followed 118 men with higher than average sperm DNA damage. Damage to sperm DNA is usually measured as a percentage on a DNA Fragmentation Index (DFI). A DFI index over 15% is considered to indicate a problem with sperm quality and all men in the study had at least this level of damage (between 15-98%).
On the seventh day of the daily ejaculation period, 81% of the men had an approximately 12% decrease in sperm DNA damage. The remaining 19% had an average 10% drop in damaged sperm levels. Other sperm parameters were not damaged by the daily program.
The lead researcher, Dr. Greening is quoted as remarking:
"The optimal number of days of ejaculation might be more or less than seven days, but a week appears manageable and favorable. It seems safe to conclude that couples with relatively normal semen parameters should have sex daily for up to a week before the ovulation date."
"In the context of assisted reproduction, this simple treatment may assist in improving sperm quality and ultimately achieving a pregnancy. In addition, these results may mean that men play a greater role in infertility than previously suspected, and that ejaculatory frequency is important for improving sperm quality, especially as men age and during assisted reproduction cycles."
Numerous studies have shown the positive effects of oral antioxidant treatments on DNA fragmentation highlighting the importance of using carefully chosen supplements and a high-antioxidant diet. The main sources of antioxidants in the diet are fruits and vegetable but also beans, nuts and seeds. Just be sure the beans don't come from a can as BPA in can liners is toxic to sperm!
