ABSTRACT
OBJECTIVE:
To study the possible pathogenesis of infertility caused by dibutyl phthalate (DBP) and investigate the effects of Yishen Shengjing Capsules (YSC, kidney-tonifying and essence-producing capsules) on DBP-induced reproductive function injury and its possible action mechanisms in male Wistar rats.METHODS:
Models of DBP-induced reproductive function injury were made in 80 male Wistar rats and another 20 were used as blank controls. After modeling, the model rats were randomly divided into a model control, a high-dose YSC, a medium-dose YSC, and a low-dose YSC group. Four weeks after intervention, all the animals were sacrified for observation of the histomorphologic changes in the testis under the light microscope, measurement of sperm concentration, motility and abnormality, and determination of the levels of serum testosterone (T), luteinizing hormone (LH) and follicle-stimulating hormone (FSH) by radioimmunoassay.RESULTS:
Compared with the blank controls, the model rats showed obvious pathological changes in testicular histomorphology, significantly decreased sperm concentration and motility, increased sperm abnormality, reduced contents of serum T and LH, and elevated the level of serum FSH (P<0.01). After 4 weeks of medication, the animals of the high-, medium-, and low-dose YSC groups, in comparison with the model controls, exhibited different degrees of recovery from testicular histomorphological damage, remarkably increased sperm concentration and motility, decreased sperm abnormality, elevated levels of serum T and LH, and reduced content of serum FSH (P<0.01). There were statistically significant differences in all the parameters above between the high-dose YSC and medium- and low-dose YSC groups (P<0.01).CONCLUSIONS:
DBP reduces sperm motility and concentration, increases sperm abnormality, causes damage to the morphological structure of the rat testis, decreases the contents of serum T and LH, and elevates the level of the serum FSH. Yishen Shengjing Capsules can improve DBP-induced productive function injury, increase sperm motility and concentration, decrease sperm abnormality, elevate the level of serum T and LH, reduce the content of serum FSH, improve the morphological structure of the testis, and thus promote the reproductive function of the male rat.Palavras-chave
