Value of hysteroscopy in management of unexplained infertility

Abstract

Abstract Objective To assess the value of hysteroscopy in unexplained infertility. Methods 200 infertile women in whom standard infertility investigations revealed no abnormalities were included in the study between January 2009 and December 2013. All women underwent hysteroscopy for diagnosis and treatment of any uterine lesion which was previously undetected by hysterosalpingography (HSG). Treated women were followed up for one year during which pregnancy rate was determined. As all other causes that contribute to infertility (other than the subtle uterine lesions) were excluded. No other infertility treatment was performed during this period. Results Of the 200 women studied, hysteroscopy revealed abnormalities in 65 (33%) women. Most uterine abnormalities were mild adhesions, small submucous myomas and polyps and their incidence was greater in women aged ≥ 30 years and women with secondary infertility. The overall pregnancy rate in the treated women within one year of follow up was 46%. Conclusion As a cause of unexplained infertility, subtle uterine abnormalities are diagnosed only during hysteroscopy and they are relatively common in infertility women. Although the presence of these abnormalities is not detected by the basic investigations for infertility, their correction seems to be necessary when infertility is desired and other infertility causes are excluded.
