Effect of Fertility Blend® Administration on the Epididymal Sperm Function Parameters of Vasectomized Mice: Physiological and Genetical Study as Model for Obstructive Azoospermic Men


Male Fertility Blend® is a new nutrient supplements containing many constituents especially a plant called Dong quai(Angelia Sinensis). The plant extract has been used to facilitate the sperm function parameters. However, the studies concern on its effects on epididymal sperms of vasectomized males and obstructive azoospermia are very rare. Thus, this investigation was designed to elucidate the role of Male Fertility Blend® (MFB) formula on the in vivo epididymal sperm characters and DNA fragmentations of vasectomized male mice as a model for man. In this study, the orally administration of 3.4 µg/ml MFB was used for vasectomized and non-vasectomized mice along 35 days. The results revealed a significant (p≤0.05) increment in certain sperm function parameters of vasectomized mice by using fertility Blend® than that of not treated by this supplement. The percentage of progressive and unprogressive active sperm motility using MFB was significantly (P≤0.05) increased compared with non-treated group. It was concluded that the MFB formula containing different sources of energy and variety of factors that sustain the epididymal sperm of healthy and vasectomized mice. Therefore this supplement can be utilized for males complaining from obstructive azoospermia and other factors of infertility.
