Damaged Sperm May Be Improved Through Frequency of Sex
Couples with fertility problems receive varying recommendations for conceiving depending on their doctor’s opinions. The medical community has long debated whether refraining from sex for several days would improve the chance of pregnancy for couples hoping to conceive. Some doctors are now recommending the best way to have a baby is to have more sex.
Research presented by Dr. David Greening of Sydney IVF, an Australian center for infertility and in vitro fertilization, indicates that increasing sexual activity may be the right approach. Dr. Greening studied 118 men with above-average sperm DNA damage. The participants were told to ejaculate every day for seven days, and the damage to their sperm count fell to 26 percent down from 34 percent. Other studies have indicated that better sperm quality results in higher pregnancy rates.
Frequent sex does decrease semen volume and it did so in the 118 participants but Dr. Greening said in a statement, “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 achieve pregnancy.” Sperm quality is also better in men who do not smoke, drink little, exercise and ingest more antioxidants.
