摘要

Acupuncture is a key component of Traditional Chinese Medicine in which needles are inserted into specific areas in the body to stimulate certain physiological reactions of the body. Clinical research shows that acupuncture is beneficial in treating a variety of illnesses, such as erectile dysfunction. Therefore, we investigated the effect of electroacupuncture (EA) stimulation of both low- and high frequencies at Guanyuan (CV4) and Zhongji (CV3) acupoints on male copulatory behavior in sexually experienced male rats. The animals were randomly divided into four groups: control, sham EA, EA, and only acupuncture. The administered low and high EA were 2 Hz and 80 Hz, respectively, for which the respective intensities were 1.5 mA (30 min/day for 5 days) and 1.5 mA (30 min once). The only acupuncture-administered group received acupunctures at CV4 and CV3 without electrical stimulation. Following the acupuncture treatments, copulatory behavior test was conducted. Eventually, animals were sacrificed and blood samples were collected for testing the serum hormonal profile including luteinizing hormone (LH), testosterone (T), and serotonin (5-HT). Results showed that low-frequency EA-treated rats exhibited increasing intromissions and ejaculation latency compared to control, sham EA, and acupuncture groups, while high-frequency EA-treated rats displayed lower intromissions and ejaculation frequency when compared with those in controls. Furthermore, serum levels of 5-HT and LH in low-frequency EA-treated rats were higher than all the other groups. These results indicate that compared to high-frequency EA, the low-frequency EA might be efficacious in the treatment of premature ejaculation, thereby improving sexual behavior.
