Previous research has shown that acupuncture can improve fertility levels in women. Fewer studies on male infertility have been conducted, although evidence suggests that acupuncture can have an effect on sperm production and quality, without causing any changes in behavior or sexual desire. A recent trial published in Fertility and Sterility has shown just how effective acupuncture can be in the treatment of this condition, leading to significant increases in the number of normal sperm and equally significant reductions in structural defects.
In the study, 28 men who were diagnosed with idiopathic infertility received acupuncture twice a week over a period of 5 weeks.
Semen samples were collected from each of the men after a 3-day period of sexual abstinence. Two samples were collected from each patient: one obtained the day before treatment began, the other after the last acupuncture treatment. Samples from the treatment group were then randomized with semen samples from 12 untreated control patients and analyzed.
Compared to the control group, motility levels increased significantly in semen samples in the men receiving acupuncture. While median motility levels increased from 32% to 37% in the control group, they increased from 44.5% to 50% in the acupuncture group.
The number and percentage of healthy sperm also increased dramatically in the acupuncture patients. At baseline, only 0.06% the sperm among men in the acupuncture group was considered "healthy," while the median number of healthy sperm calculated in ejaculate was 0.04 x 10 6 (40,000). After 10 sessions of treatments, the median percentage of healthy sperm had increased more than four-fold, to 0.26%, while the median number of healthy sperm per sample had reached 0.2 x 10 6 (200,000).
In addition, significant changes in sperm structure and quality were seen in the samples from the acupuncture group. Before treatment, only 22.5% of the sperm samples in the acupuncture patients contained normal-shaped acrosomes, a cap-like structure that develops over the anterior portion of a sperm cell's nucleus. After treatment, the median percentage of normal acrosome shapes showed a "statistically significant improvement" to 38.5%.
Similarly, the percentage of sperm with a normal axoneme pattern increased significantly among men receiving acupuncture. (The axoneme is a microscopic structure that contains a series of tubules arranged in a distinct pattern, and is believed to aid in sperm motility.) Prior to the start of the study, the correct axoneme pattern was present in 52% of sperm in the control group, but only 46.1% in the acupuncture group. After 5 weeks of therapy, the median percentage increased to 52.2% in acupuncture patients, but actually decreased to 38.2% in the control group.
The authors concluded that despite the inability of acupuncture to significantly reduce some sperm abnormalities, the treatment could be used to improve overall sperm quality, leading to the possibility of increased fertility.
