Abstract:Objective To study the clinical effects of Qilin pills combined with HMG on patients with luteinized unruptured follicle synodrome (LUFS). Methods Sixty-nine patients with LUFS were assigned into a trial group (group A, 35 cases) and a control group (group B, 34 cases) who were treated with Qilin pills combined with HMG and HMG alone, respectively. The ovulation rate, natural pregnancy rate and the levels of serum sex hormones (LH, FSH, E2 and P) of the two groups were compared after treatment. Results The ovulation rates (76.1% vs 59.8%) and natural pregnancy rates (40.0% vs 17.6%) were significant different between the groups A and B after treatment (P < 0.05). In additional, the levels of LH and E2 on the follicle maturity day, and the level of P in one week after induced ovulation in the group A were obviously higher than those in the group B (P < 0.05). Conclusions Qilin pills combined with HMG can significantly enhance the ovulation and natural pregnancy rate in patients with LUFS.
