Background/Objectives: Human papillomavirus (HPV) is the most common sexually transmitted virus worldwide and is frequently detected in women of reproductive age. In this population, HPV-related diseases and their management may affect reproductive health and pregnancy outcomes. This narrative review summarizes the current evidence on HPV infection and HPV-related diseases in relation to fertility, pregnancy, and neonatal outcomes, and discusses preventive strategies, with a particular focus on HPV vaccination. Methods: An international, multidisciplinary team of clinicians from the European Society of Gynaecological Oncology (ESGO) Prevention Committee reviewed the literature on HPV, HPV-related diseases, HPV vaccination, and reproductive outcomes, without time restrictions, prioritizing studies judged to meaningfully reflect the available evidence. Results: The most consistent evidence linking HPV-related conditions to adverse pregnancy outcomes relates to the treatment of cervical precancer, particularly excisional procedures, which are associated with an increased risk of preterm birth and mid-trimester pregnancy loss. In contrast, evidence that maternal HPV detection alone causes adverse pregnancy or neonatal outcomes remains limited and inconsistent. Data on HPV infection and subfertility are scarce and heterogeneous. Management of HPV-related lesions during pregnancy remains challenging and requires careful balancing of maternal safety with avoidance of unnecessary interventions. HPV DNA has been detected in neonatal samples, but convincing evidence for clinically relevant vertical transmission is lacking. Available data indicate that inadvertent HPV vaccination shortly before or during pregnancy is not associated with adverse pregnancy outcomes. Conclusions: Current evidence suggests that reproductive risks are more strongly associated with the treatment of HPV-related diseases than with HPV infection itself. Preventive strategies—especially HPV vaccination—remain central to reducing HPV-related disease burden. Although HPV vaccines are not routinely recommended during pregnancy, evidence supports the safety of inadvertent exposure around conception or during gestation, while potential long-term benefits of vaccination regarding reproductive health require further study.

Introduction: Adult-type granulosa cell tumors (AGCTs) are rare ovarian neoplasms with a low overall incidence of recurrence, and also data on secondary recurrence and survival after relapse remain limited. This study aimed to identify factors associated with secondary recurrence and survival after recurrence in patients with recurrent AGCTs.

Background/Objectives: The levonorgestrel-releasing intrauterine device (LNG-IUD) is widely used as a long-acting reversible contraceptive and as a therapeutic option for heavy menstrual bleeding, endometriosis, adenomyosis, and endometrial hyperplasia. Although its predominant effect is local, systemic levonorgestrel exposure has raised questions regarding its potential influence on cancer risk. This review aims to summarise and critically appraise the available evidence on the association between LNG-IUD use and gynaecologic, breast, and selected non-gynaecologic malignancies (including colorectal, lung, pancreatic, gastric, thyroid, skin [melanoma], and haematological cancers). Methods: A structured narrative review was developed by a multidisciplinary expert group affiliated with the European Society of Gynaecological Oncology (ESGO) and the European Society for Gynaecological Endoscopy (ESGE). PubMed/MEDLINE, Embase, and Scopus were searched in December 2024 without publication-date restrictions. We critically appraised epidemiological and clinical evidence on LNG-IUD use and breast, endometrial, ovarian, cervical, and selected non-gynaecologic cancer risks, prioritising population-based cohorts, registry-based studies, case–control studies, systematic reviews, and meta-analyses. Results: The strongest and most consistent evidence supports a substantial reduction in endometrial cancer risk among LNG-IUD users, with a possible protective association also suggested for ovarian cancer. Available data do not indicate a clear increase in cervical cancer, CIN3+, or invasive cervical disease. In contrast, evidence for breast cancer remains heterogeneous, with some registry-based studies suggesting a modest relative increase and other cohort or case–control studies showing no significant association. Evidence regarding non-gynaecologic cancers remains limited and inconclusive. Conclusions: Overall, current evidence suggests that the LNG-IUD has a favourable oncological safety profile, with the strongest evidence supporting a significant reduction in endometrial cancer risk and a potential protective effect against ovarian cancer. There is no evidence pointing to increased risk of cervical cancer. However, results related to breast cancer are mixed, and a slight risk increase cannot be ruled out; thus, counselling should be personalised based on the indication, menopausal status, duration of use, and individual breast cancer risk.
