So far,only a few studies about the effects of nature cure on male infertil
ity have been published. Most data are available for application of acupunc
ture in andrological patients. Since randomized, double-blind and placebo-c
ontrolled studies cannot be easily performed with acupuncture, it is diffic
ult to interpret the possible effects on semen quality. Significant improve
ment in pregnancy rates and standard semen parameters after treatment with
Chinese medical herbs has been reported in the Chinese scientific literatur
e. However, almost all manuscripts are written in Chinese language or are n
ot available in German libraries. Therefore, only English abstracts with in
sufficient data can be evaluated. Studies about homeopathic treat ment of m
ale infertility have not yet been performed. Most reports about positive ef
fects on semen quality are based on unpublished observations and case repor
ts.
