Analysis of therapeutic outcomes of polycystic ovary syndrome patients with hyperprolactinemia / 中华妇产科杂志

ABSTRACT

Objective To study effect of drug treatment in polycystic ovary syndrome patients withhyperprolactinemia.Methods We retrospectively studied 63 women with polycystic ovary syndrome and hyperprolactinemia from the Reproductive Medicine Center,Provincial Hospital between January 2005 andMarch 2007.According to the beginning time of bromocriptine,all women were divided into two groups.Group Ⅰ was composed of 48 cases who received bromocriptine administration before induction of ovulation cycles,and the dose of bromocriptine was modulated depending on the level of serum prolactin.When serum prolactin was controlled at normal levels,we decreased the dosage of bromocriptine step by step(1.25 mgonce),and then continued the treatment at maintenance dosage for no less than 3 weeks.After a baselineultrasonographic examination on day 3,patients were treated with clomiphene citrate at a dosage of 100 mg (2 tablets/day)for 5 days of a normal cycle or progesterone-induced bleeding.On day 9,we monitored the growth conditions of follicles routinely with trans-vaginal uhrasound.If there was no dominant follicle,we added human menopausal hormone(hMG,75 U/d)to the protocol.Human chorionic gonadotropin(hCG,6000-10000 IU)was given intramuscularly when the mean diameter of a follicle reached at least 18 mm.At the same time we instructed the patients to have sexual intercourses or carried out artificial inseminationsbefore and after ovulation.Group Ⅱ were 15 cases in which induction of ovulations were commenced almostsimultaneously with beginning of bromocriptine.The same protocol was given to patients in group Ⅱ.The procedures of ovulation induction and the outcomes of treatment were analyzed and compared.Results Compared with groupⅡ.the days of using hMG in Group Ⅰ was shorter by instructing the time of sexualintercourse.The difference was significant(P=0.004).And there were similar results in the artificial insemination cycles(P=0.009).The rate of pregnancy in group Ⅰ(40%,19/48)was higher than that in groupⅡ(27%,4/15),but the difference was not obvious(P=0.525).Conclusion Bromocriptine administration before the stimulated ovulation therapy can decrease the total dosage and treatment course of ovulating drugs.Induction of ovulations simultaneously with start of bromocriptine therapy can shorten the treatment time of infertility.
