Many infertile man have an increased proportion of genetically abnormal sperm. Normally this is not an issue, because the sperm number is so small, that it fails to fertilise an egg. But in case of ICSI, the potentially genetically abnormal sperm is injected directly in to an egg. This increases the risk risk for ICSI failure as well as the risk of transmitting diseases such as Klinefelter’s syndrome, Down’s syndrome, congenital heart defects, etc.
Scientists from university of Kent conducted research on six men who had very high levels of chromosome abnormalities in their sperm. After a course of traditional Chinese medicine each of the six men participating in the study showed a significant reduction in the proportion of sperm genetic abnormalities.
This research offers promise to male infertility patients. However more research is needed to convince the skeptics.
