title: Pregnancy rates following hysteroscopic polypectomy, myomectomy, and a normal cavity in infertile patients.
abstract: Objective: To assess the reproductive benefits of hysteroscopic myomectomy and polypectomy for infertility when compared to infertile couples with a normal cavity at hysteroscopy.Material and Methods: All patients with a diagnosis of infertility who underwent hysteroscopic evaluation by a single surgeon between 1975 and 1996 were sent a questionnaire as routine follow-up regarding their reproductive history. All 100 subjects who were located responded to the questionnaire, and 78 subjects met the inclusion criteria; age <45 years, 12 months of infertility, and 18 months of follow-up with attempts to conceive including in vitro fertilization in patients with bilateral tubal occlusion.Results: Of the 78 subjects, 36 had undergone a myomectomy, 23 a polypectomy, and 19 had a normal cavity. Among the three groups there was no significant difference in their ages, types of infertility, length of infertility, or follow-up after the procedure. Using the Cox proportional hazard model, and adjusting for age, polypectomy patients had a significantly higher pregnancy rate (RR 3.89, P <.01) and a higher live birth rate (RR 2.42, P =.06) than patients with a normal cavity. Patients who had undergone a myomectomy also had a higher pregnancy rate (RR 2.02, P =.11) and live birth rate, but this did not achieve statistical significance. Pregnancy following a hysteroscopic myomectomy was associated with a larger fibroid resection (3.15 cm vs 2.5 cm P =.05). The spontaneous abortion rate following the myomectomy, polypectomy, or a normal study was equivalent, 28.1%, 23.1%, and 29.2%, respectively.Conclusions: Both hysteroscopic polypectomy and hysteroscopic myomectomy appear to enhance fertility when compared to infertile patients with a normal cavity. Despite concern that hysteroscopic resection of a large myoma may ablate a large surface area of the endometrial cavity, patients with larger myomas were more likely to conceive following resection.
