LONDON (Reuters) – Having sex every day improves the quality of
men's sperm and is recommended for couples trying to conceive,
according to new research.
Until now doctors have debated whether or not men should refrain
from sex for a few days before attempting to conceive with their
partner to improve the chance of pregnancy.
But a new study by Dr David Greening of Sydney IVF, an
Australian center for infertility and in vitro fertilization (IVF)
treatment, suggests abstinence is not the right approach.
He studied 118 men with above-average sperm DNA
damage and found the quality of their sperm increased
significantly after they were told to ejaculate daily for seven
days.
On average, their DNA fragmentation index -- a measure of sperm
damage -- fell to 26 percent from 34 percent, Greening
told the European Society
of Human Reproduction and Embryology in Amsterdam
Tuesday.
Frequent sex does decrease semen volume but for most men this is
not a problem.
"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," he said in a statement.
"In the context of assisted reproduction, this simple treatment
may assist in improving sperm quality and ultimately achieving a
pregnancy."
Greening said it was likely frequent ejaculation improved the
quality of sperm by reducing the length of time they were exposed
to potentially damaging molecules called reactive oxygen species in
the testicular ducts.
