Background With increasing cases of iatrogenic premature ovarian insufficiency (POI), more clinicians are required to counsel patients regarding the gonadotoxic effects of iatrogenic treatments. This survey aimed to explore obstetricians and gynaecologists' knowledge regarding iatrogenic POI. A national online questionnaire survey was conducted across China. Respondents were asked to select the iatrogenic condition(s) that can cause POI based on their experience and knowledge. Results Of the 5523 returned questionnaires, 4995 were analysed. Among tumour therapies causing POI, most respondents agreed that radiotherapy (73.5% of respondents) and chemotherapy (64.1%) are risk factors for POI. While only 6.5 and 7.8% of the gynaecological oncologists believed that tumour immunotherapy and tumour-targeting therapy, respectively, may cause ovarian impairment, 31.8 and 22.2% of the non-gynaecologic oncologists believed that these therapies could affect ovarian health. Most respondents believed that ovarian cystectomy (54.4%) was a risk factor for POI. In contrast, only a few respondents believed that hysterectomy with bilateral salpingectomy (39.6%) and uterine artery embolisation (33.5%) could cause ovarian impairment. Only 30.5% of respondents believed that immunosuppressants (ISs) increased the risk of POI. Views differed with experience and hospital setting. Conclusions The knowledge of gonadal toxicity due to traditional tumour treatments is generally high among Chinese obstetricians and gynaecologists. A misunderstanding may exist in primary care hospitals and general gynaecologists regarding a link between novel tumour treatments and POI, owing to the lack of convincing evidence. Knowledge of POI caused by hysterectomy and ISs should be improved. Keywords: Premature ovarian insufficiency, Iatrogenic menopause, Ovarian impairment, Knowledge, National survey
