Effect of Toxic Compounds Extracted from Microalgae Oscillatoria limosa (Roth) Agardh on the Fertility of White Male Mice Mus musculus L.

Abstract

The effect of toxic compounds extracted from cyanobacteria Oscillatoria limosa isolated from Abu-Alkaseeb rivers in the southern Iraq was studied, water samples  were collected from rivers, and cultured in chu-10 medium .Supernatant of toxic extract from biomass was extracted and  test its effects on the fertility of male mice .The present study reveal   that di(2-ethyl hexyl) phthalate and phytol compounds effected on the fertility of male mice based on the sperm count ,sperm abnormalities and testosterone hormone level. The current study concluded that the toxic compounds extracted of Oscillatoria limosa had a positive effect on fertility of Mus musculus these effects represented in increasing in abnormal sperms ,decreasing  of sperm count and testosterone hormone levels compared with control group .

Keywards: oscillatoria limosa, sperm count, testosterone hormone.
