Study on the effects of letrozole and clomiphene on the treatment of ovulation induction and the changes of reproductive hormone in the patients with polycystic ovary syndrome
Objective To study the effects of letrozole and clomiphene on the treatment of ovulation induction and the changes of reproductive hormone in the patients with polycystic ovary syndrome.Methods In Zhenhai District People's Hospital from January 2015 to December 2016, 100 cases with polycystic ovary syndrome as the research object in this study, were randomly divided into the control group and the experimental group, 50 cases in each group.The control group were treated with clomiphene, the experimental group were given letrozole combined clomiphene.The levels of reproductive hormones, ovulation rate and pregnancy rate were compared in the two groups.Results The ovulation rate was 90%, pregnancy rate was 46%, the numbers of follicles was(1.2±0.4).In the control group, the ovulation rate was 72%, the pregnancy rate was 22%, and the number of follicles was(2.2±0.5).The results showed that the ovulation rate and pregnancy rate in the experimental group were significantly higher than those in the control group, with statistical significance(P<0.05).The number of follicles in the control group was significantly higher than that in the control group, with statistical significance(P<0.05).There was no significant difference between the experimental group and the control group in the time of follicular maturation, which was not statistically significant.The levels of reproductive hormones in the experimental group were significantly lower than those in the control group, with statistical significance(P<0.05).Conclusion Letrozole combined clomiphene can improve the ovulation rate and pregnancy rate, reduce the reproductive hormone level, which has clinical application value.
