The concentration of the studied uterine elements, with the exception of P, correlated with the concentration of their homologue in the serum at different stages of the cycle. It is believed that the concentration of serum Na, K, Mg and Ca maintains the intrauterine concentrations at the physiological level for the survival of the gametes and the embryo.
Significant differences in the uterine concentrations of Na, K and P were noted between the groups at different stages of the cycle. These various concentrations as well as the nonsignificant variations of the uterine secretions might explain the infertility in the abnormal group.
相似文献No significant changes were noted in Na and Ca concentration in either serum or uterine fluid. On the other hand, significant changes in the Mg, K and P were observed. Both drugs have caused a decrease in the content of Mg in the serum (P<0.05) during diestrus, a fall in the level of uterine K (P<0.01) during proestrus and a decrease of P during proestrus both in serum (P<0.001 after dexamethasone treatment) and in uterine fluid (P<0.001 for both drugs).
It is obvious that the two drugs change the chemical composition of blood and endometrial secretions. This could jeopardize the survival of the spermatozoids and of the ovum as well as the fertilization and the implantation processes.
