Electroacupuncture improved stress urinary incontinence—that's when a woman can experience an involuntary loss of urine such as when sneezing or coughing—but acupuncture did not increase the likelihood of childbirth among women with infertility, according to two studies published by JAMA.

Stress urinary incontinence (SUI) is an involuntary loss of urine on physical exertion, sneezing, or coughing. Electroacupuncture involving the lumbosacral region (near the small of the back and the back part of the pelvis between the hips) may be effective for women with SUI, but evidence is limited. Baoyan Liu, M.D., of the China Academy of Chinese Medical Sciences, Beijing, China, and colleagues randomly assigned 504 women with SUI to receive 18 sessions (over 6 weeks) of electroacupuncture involving the lumbosacral region (n = 252) or sham electroacupuncture (n = 252) with no skin penetration on sham acupoints. For the electroacupuncture, paired electrodes were attached to needle handles; stimulation lasted for 30 minutes with a continuous wave of 50 Hz and a current intensity of 1 to 5 mA.

Among the randomized participants, 482 completed the study. The researchers found that at week six, the electroacupuncture group had a greater decrease in average urine leakage than the sham group. The effects persisted 24 weeks after treatment. The incidence of adverse events was low.

"Further research is needed to understand long-term efficacy and the mechanism of action of this intervention," the authors write.

Limitations of the study are noted in the article.

In another study, Xiao-Ke Wu, M.D., Ph.D., of Heilongjiang University of Chinese Medicine, Harbin, China, and colleagues randomly assigned 1,000 women with to active or control acupuncture administered twice a week and clomiphene or placebo administered for five days per cycle, for up to four cycles.

Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility (when the ovaries do not release an egg during a menstrual cycle) and is reported to affect 5 percent to 10 percent of women of reproductive age. Clomiphene citrate is a first-line, inexpensive treatment to induce ovulation in women with PCOS; however, it has had a high failure rate. New treatments are needed for this population. Acupuncture is used to induce ovulation in some women with polycystic ovary syndrome, without supporting clinical evidence.

In this study, the active acupuncture group received deep needle insertion with combined manual and low-frequency electrical stimulation; the control acupuncture group received superficial needle insertion, no manual stimulation, and mock electricity.

Among the women in the study, 250 were randomized to each group; a total of 926 women (93 percent) completed the trial. The researchers found that the live birth rate was significantly higher in the women treated with clomiphene than with placebo (28.7 percent vs 15.4 percent) and not significantly different between women treated with active vs control acupuncture (21.8 percent vs 22.4 percent).

"This finding does not support acupuncture as an infertility treatment in such ," the authors write.

A limitation of the study was the fixed acupuncture protocol; personalized treatment might have been more effective.
