المستخلص:
يعد العقم واحدة من المشاكل الاجتماعية المهمة في معظم انحاء العالم.استنادا الى الاحصائيات الحالية حوالي 15% من المتزوجين يواجهون العقم. يؤدي تقييم السائل المنوي غير الطبيعي للاستروجينات الى تشخيص قلة اعداد النطف ونشاطها وشكلها الطبيعي ومن ناحية اخرى تؤثر | Infertility is one of the most critical social problems in the all of population world. According to the current statistics, about 15% of married couples face with infertility. Assessment of abnormal semen parameters leads to diagnosis of oligoasthenoteratozoospermia, and in others, it leads to isolated abnormalities of sperm concentration, motility, and morphology, due to the lack of differentiable or correctable etiology, Both clomiphene citrate and tamoxiphene citrate, as an anti - estrogen, is the most common prescribed medication for male infertility. In humans, ant estrogens interfere with the normal negative feedback of sex steroids at the hypothalamus and pituitary, thereby increasing endogenous gonadotropin releasing hormone (GnRH) secretion from the hypothalamus and follicle stimulating hormone (FSH) and luteinizing hormone (LH) secretion directly from the pituitary. Objective : The objective of this study was to investigate the effect of clomiphene citrate (CC) and tamoxiphene citrate (TC) administered to male mice on quality of sperm parameters.Materials and Methods : Ninety six male mice were divided into two major groups, and every one of these groups was subdivided into three minor groups involving control and two treated groups. In the CC study, 48 mice were administrated orally 0, 0.0125 mg and 0.025 mg as control (G 1), low dose (G 2) and high dose (G 3) for 42 days. While, in the TC study, 48 mice were administrated orally 0, 0.01 mg and 0.02 mg as control (G 1), low dose (G 2) and high dose (G 3) for 42 days. Then, the male mice were sacrificed, both vas deferens were collected and assessment sperm parameters involving sperm concentration, sperm motility and activity, and normal sperm morphology. Results : The results of present study appeared that the use high dose of CC or TC significantly increment (P<0.05) sperm concentration as compared to control groups. However, use high dose of CC significantly increment (P<0.05) percentages of sperm motility and normal sperm morphology. Meanwhile, the percentage of progressive sperm motility was increased significantly (P< 0.05) when low CC dose administered as compared to control and high CC dose groups. In this study, percentages of sperm motility, progressive sperm motility and normal sperm morphology showed best elevation when used low TC dose as compared to both control and high TC dose groups. High TC dose causes significant increment (P<0.05) in the percentage of sperm agglutination when compared to control and low TC dose groups.Conclusions : Based on the results of this study, it can be concluded that the administration of high dose of either CC or TC increases sperm concentration, while administration of low dose of either CC or TC enhances progressive sperm motility.
