OBJECTIVE： To investigate the effects of Qigong pills decoction combined with chemical drugs on hormone levels of polycystic ovarian syndrome （PCOS） patients complicated with infertility. METHODS： A total of 98 PCOS patients complicated with infertility selected from gynaecology department of our hospital during Jul. 2015-Jun. 2016 were divided into observation group and control group according to random number table， with 49 cases in each group. Control group was given Clomiphene citrate tablet 50 mg orally， qd， for consecutive 5 d； B-ultrasonography for follicle development was monitored at the 11th day of menstruation， and then they were given Chorionic Gonadotropin for injection 2 000 U intramuscularly， qod， if there was not dominant follicle ＞10 mm till the diameter of follicle reached 18 mm. Observation group was additionally given one dose of Qigong pills decoction， every day 400 mL after decocted with water， each 200 mL for morning and night， on the basis of control group. After 3 months of treatment， the levels of FSH， LH， PRL， E2， T， DHEA-S and SHBG， the endometrial thickness， the number of mature follicle and pregnancy rate were compared between 2 groups. RESULTS： Before treatment， there was no statistical significance in the levels of FSH， LH， PRL， E2， T， DHEA-S or SHBG between 2 groups （P＞0.05）. 3 months after treatment， the levels of PRL， T and DHEA-S in 2 groups were decreased and E2， SHBG were increased significantly； the levels of FSH， PRL， T and DHEA-S in observation group were significantly lower than control group， while the levels of E2 and SHBG were significantly higher than control group， with statistical significance （P＜0.05）. Endometrial thickness of observation group were significantly higher than that of control group； pregnancy rate （18.37％） was significantly higher than control group （4.08％）， with statistical significance （P＜0.05）. CONCLUSIONS： Qigong pills decoction combined with chemical drugs can help to improve pregnancy rate and regulate serum hormone level in the treatment of PCOS complicated with infertility.
