الملخص EN

The study aimed to find out the role of extract Rosmarinus officinalis to resist the toxic pesticide Chlorpyrifos on reproductive efficiency of male rats and some fertility standards as a study of sperm parameters and the concentration of hormones.

The experiment has involved the use of (40) male adults were distributed randomly to (4) groups equally, each group (10) animals.

control group (C) administered with distilled water, and first group (T1) gavage pesticide Chlorpyrifos concentration (20) mg / kg of body weight, and second group (T2) administered aqueous extract Rosmarinus officinalis (100) mg / kg, and Third group (T3) administered pesticide Chlorpyrifos a concentration of 20 mg / kg and extract of rosemary (100) mg / kg for 60 days.

At the end of the experiment were dissected five animals after taking blood samples for the purpose of obtaining serum to assess hormone levels Testosterone and stimulating follicle and LH, then animals explained and eradicated the testes , The tail of the epididymis was taken to study sperm parameters, while the remaining five animals from each group were isolated for the purpose of fertility test them and to study the male's ability to fertilization and cause pregnancy.

The results of the statistical analysis obtain significant decrease (P <0.05) levels of hormones (T, FSH, LH) and a significant decrease (P <0.05) for the parameters of sperm studied for a pesticide (T1) compared with the control group and the rest of the treatment results were mixed differences close totals.

Conclude from this study that the aqueous extract of Rosmarinus officinalis treatment has allowed to reduce toxicity and improve the pesticide chlorpyrifos on sperm parameters and the concentration of the hormones studied.
