子宫内膜息肉对不孕患者的影响

子宫内膜息肉（endometrial polyps，EP）是子宫内膜的局部良性病变，常发生于育龄期女性。观察性研究表明，EP对生育有不利的影响，但EP的发病机制尚不明确。EP的诊断方法通常包括二维阴道超声、三维阴道超声、生理盐水宫腔声学造影（saline infusion sonohysterography，SIS）、子宫输卵管造影（hysterosalpingography，HSG）及宫腔镜检查，宫腔镜联合活组织检查是EP诊断的金标准。在大多数情况下，较小且无症状的息肉可采取期待疗法，然而为了提高自然受孕率或辅助生殖成功率，对于不孕症患者，采取手术切除EP方法仍是首选的治疗方案，而且疗效显著。相关证据表明，在促排卵的过程中，行EP切除术，可提高体外受精（in vitro fertilization，IVF）的成功率。

The Influence of Endometrial Polyps on Infertile Patients

Endometrial polyps (EP) is a benign local lesion of the endometrium. It is common in women of childbearing age. Observational studies have shown that EP has an adverse effect on fertility, but its pathogenesis is not clear. Diagnosis methods of EP usually include two-dimensional transvaginal ultrasound and three-dimensional transvaginal ultrasound, saline infusion sonohysterography (SIS) and hysterosalpingography (HSG) and hysteroscopy. Hysteroscopy and biopsy is the gold standard for the diagnosis of EP. In most cases, small and asymptomatic polyps can adopt expectant therapy, however, in order to improve the natural conception or pregnancy rate of assisted reproduction, surgical resection of endometrial polyps is still the first choice for the treatment of infertility patients, and the curative effect is remarkable. Relevant evidence suggests that endometrial polypectomy in the course of ovarian stimulation improves the success rate of in vitro fertilization.
