Abstract

Background: Speramax® was found to play an important role in sperm function characters and males reproductive performance with no studies on its effects on the oocyte maturation and embryonic development in females. Objective: The goal of the present work was to examine the effect of Speramax ® on oocyte maturation ,ova quality , embryonic development and live birth using mice as a model for mammals . Materials and Methods: In this study, Speramax ® was administrated orally for 1, 2 and 4 weeks . One hundred and ten female mice were randomly divided into four groups , the first group was superovulated(SUO) while the second group was treated by Speramax® with SUO and the third group was spontaneously ovulated (SPO) and treated with Speramax ® and the forth group was spontaneously ovulated (SPO ) and served as control group .Another forty-eight female mice were used for the determination of the number of live births . Results: The results indicated that treatment with Speramax® showed a positive effect on oocytes maturation in vivo. There was a highly significance ( p˂ 0.0001) improvement in the number of mature oocytes following treatment with Speramax® in SPO and SUO mice compared with SPO and SUO mice not treated with Speramax® . The percentage of embryonic development after 24 and 48 hours of mating in treated groups with Speramax® was significantly ( p˂ 0.05) higher than SPO and SUO mice .The study showed that the quantity and quality of embryos obtained from the treated groups were superior to that of the untreated group . Conclusions: It was concluded that the Speramax® greatly improved oocyte maturation, early embryonic development and embryo grading quality embryos with an increase in the numbers of mice live births.
