Acupuncture Improves Fertility Odds

Just read the blurb for next weeks article
http://www.abc.net.au/catalyst/stories/promo.htm

“…experts say that science and technology has reached a plateau, and improvements in the success of these fertility treatments may only come from entirely different medical traditions - like acupuncture”

so I’m wondering where this proposed increase in fertility comes from, and how sticking needles into nerve junctures would help.
any ideas?
