Sexually transmitted infections (STIs) are a significant global health concern, affecting millions of people worldwide, particularly sexually active adolescents and young adults. These infections, caused by various pathogens, including bacteria, viruses, parasites, and fungi, can have profound implications for women’s reproductive health and fertility. This review explores the role of vaginal and uterine infections in women’s infertility, focusing on the most common pathogens and their impact on reproductive outcomes. Bacterial infections, such as those caused by intracellular bacteria (Mycoplasma, Ureaplasma, and Chlamydia), Neisseria gonorrhoeae, and bacterial vaginosis, are among the most prevalent causes of infertility in women. Studies have shown that these infections can lead to pelvic inflammatory disease, tubal occlusion, and endometrial damage, all of which can impair fertility. Mycobacterium tuberculosis, in particular, is a significant cause of genital tuberculosis and infertility in high-incidence countries. Viral infections, such as Human papillomavirus (HPV) and Herpes simplex virus (HSV), can also affect women’s fertility. While the exact role of HPV in female infertility remains unclear, studies suggest that it may increase the risk of endometrial implantation issues and miscarriage. HSV may be associated with unexplained infertility. Parasitic infections, such as trichomoniasis and schistosomiasis, can directly impact the female reproductive system, leading to infertility, ectopic pregnancy, and other complications. Fungal infections, such as candidiasis, are common but rarely have serious outcomes related to fertility. The vaginal microbiome plays a crucial role in maintaining reproductive health, and alterations in the microbial balance can increase susceptibility to STIs and infertility. Probiotics have been proposed as a potential therapeutic strategy to restore the vaginal ecosystem and improve fertility outcomes, although further research is needed to establish their efficacy. In conclusion, vaginal and uterine infections contribute significantly to women’s infertility, with various pathogens affecting the reproductive system through different mechanisms. Early diagnosis, appropriate treatment, and preventive measures are essential to mitigate the impact of these infections on women’s reproductive health and fertility. Full article

Background/Objectives: Hysterosalpingography (HSG) is pivotal in delineating tubal pathology, but is associated with pain and exposure to ionizing radiation. This study investigated which reproductive factors predict HSG-identified tubal pathology. Methods: From May 2016 to August 2023, 3322 infertile females with HSG (mean age 33.9 ± 4.3 years) were assessed for fallopian tube status. Results: HSG indicated that 2764 had patent tubes while 558 (16.8%) had non-patent tubes. Unilateral and bilateral absence of free contrast spillage occurred in 377 (11.3%) and 181 (5.4%) cases, respectively. Non-spillage, denoted as non-patency, was seen in 148 (4.5%) and 153 (4.6%) right and left cases, respectively. Tubal occlusion was observed in 181 (5.4%) and 159 (5.4%) right and left cases, respectively. Hydrosalpinx was found in 37 (1.2%) right and 58 (1.7%) left cases. Multivariate logistic regression revealed CT-IgG positivity (odds ratio [OR]: 1.57), endometrioma (OR: 1.64), and fibroids (OR: 1.58) as independent factors for increased non-patency. CT-IgG positivity (OR: 1.92) and fibroids (OR: 1.88) were significant risk factors for occlusion. Painful defecation (OR: 2.79), CT-IgA positivity (OR: 2.09), CT-IgG positivity (OR: 2.07), and endometrioma (OR: 3.11) were significant risk factors for hydrosalpinx. Conclusions: In females with painful defecation, CT-IgG positivity, endometrioma, and fibroids, HSG may be used as a second-line investigation, with laparoscopy as the preferred assessment tool.

Introduction: While tubal occlusion is a prevalent cause of infertility, accounting for 11–35% of infertility cases among women, there remains a limited understanding of the factors influencing clinical pregnancy following in vitro fertilization (IVF). Methods: In our retrospective, cross-sectional cohort study conducted at a single tertiary center, medical records of women aged 19 to 43 years were analyzed. Logistic regression models were employed to identify the prognostic factors associated with clinical pregnancy after IVF in patients with tubal factor infertility, excluding cases with hydrosalpinx. Results: Data from 219 women diagnosed with tubal occlusion were compared to 1140 cases with non-tubal indication, covering a total of 1359 IVF cycles. A lower maternal age (adjusted odds ratio [AOR]: 0.89, p = 0.001) and a higher embryo quality (AOR: 1.26, p = 0.01) emerged as important factors in clinical pregnancy in the tubal infertility group. Moreover, a lower maternal (AOR:0.91, p < 0.01) and paternal age (p = 0.001), and favorable semen quality (AOR: 1.32, p = 0.03) were critical determinants in the non-tubal infertility group. BMI was generally higher in tubal infertility patients (p = 0.01). Furthermore, FSH level (AOR: 0.93, p = 0.004), AMH level (p < 0.04), number of embryos transferred (AOR: 2.04, p < 0.001), and embryo quality (AOR: 1.26, p < 0.001) came into prominence only in the non-tubal infertility group. The clinical pregnancy rate (34.2%) of women with tubal occlusion did not differ significantly from those in other forms of infertility undergoing IVF (35.4%). Conclusions: Although tubal infertility is typically anticipated to yield the highest clinical pregnancy rates following IVF, it is crucial to acknowledge that both maternal and paternal characteristics can also significantly impact the outcomes.

Background and Objectives: Fallopian tubal pathology is a primary risk factor for female infertility, with simple proximal disease and proximal disease extending more distally being more common than pure distal occlusion. Proximal tubal occlusion is often attributed to ascending events, such as pelvic inflammatory disease. Conversely, while distal occlusion can also be attributable to ascending pelvic inflammatory disease, it can also have a pelvic origin, such as through endometriosis and ruptured appendicitis. The aim of this study was to identify certain causes of infertility and their association with tubal occlusion. The focus was on the location of tubal occlusion, uni- versus bilateral occlusion, and other causes of infertility, including male factors. Methods: In a retrospective study cohort study, 373 women aged between 18 and 40 years, treated from 1 January 2017 to 31 December 2022, were included. Fallopian tube patency was tested using either hysterosalpingography, hysterosalpingo-contrast sonography, or laparoscopic chromopertubation. Results: In total, 95 of 373 women (25.5%) revealed at least one occluded tube, with unilateral occlusion being more common than bilateral occlusion (60/95, 63.2% vs. 35/95, 36.8%). The majority of tubal occlusions occurred proximally (86.2%). According to the adjusted multivariate regression models, the presence of hydrosalpinx (odds ratio, OR, 13.323, 95% confidence interval, CI: 2.679–66.253, p = 0.002), myomas (OR 2.108, 95%CI: 1.008–4.409; p = 0.048), and an abnormal sperm test result of the male partner (OR 2.105, 95%CI: 1.156–3.833; p = 0.015) were statistically significant associated factors for tubal occlusion. Conclusions: Fallopian tube patency testing is still of major relevance in fertility evaluation. The presence of uterine myomas, hydrosalpinges, and a male factor significantly increase the risk.

Hydrosalpinx is a fluid occlusion and distension of the fallopian tubes, often resulting from pelvic inflammatory disease, which reduces the success of artificial reproductive technologies (ARTs) by 50%. Tubal factors account for approximately 25% of infertility cases, but their underlying molecular mechanisms and functional impact on other reproductive tissues remain poorly understood. This proteomic profiling study applied sequential window acquisition of all theoretical fragment ion spectra mass spectrometry (SWATH-MS) to study hydrosalpinx cyst fluid and pre- and post-salpingectomy endometrial fluid. Among the 967 proteins identified, we found 19 and 17 candidate biomarkers for hydrosalpinx in pre- and post-salpingectomy endometrial fluid, respectively. Salpingectomy significantly affected 76 endometrial proteins, providing insights into the enhanced immune response and inflammation present prior to intervention, and enhanced coagulation cascades and wound healing processes occurring one month after intervention. These findings confirmed that salpingectomy reverses the hydrosalpinx-related functional impairments in the endometrium and set a foundation for further biomarker validation and the development of less-invasive diagnostic strategies for hydrosalpinx.

Objective: To identify the prevalence and risk factors for chronic endometritis (CE) with tubal factors and the correlation between chronic endometritis and tubal factors among infertile populations. Method: A total of 52 patients with chronic endometritis (CE group) who underwent laparoscopy and hysteroscopic surgery were recruited between July 2020 and December 2021. A total of 38 patients without chronic endometritis (non-CE group) were included as a control. Patients with endometriosis and intra-uterine abnormalities were excluded. Endometrial samples were collected during surgery for CD138 immunohistochemistry staining for the diagnosis of CE. Preoperative information (including age, reproductive health characteristics, previous medical and surgical history), intra-operative information (including the patency of the fallopian tube, the presence of hydrosalpinx, score and the grade of tubal lesion condition) and post-operative information (counts of CD138-positive HPF in the endometrial specimen) were collected. Result: A multivariate analysis revealed that tubal factors with unilateral or bilateral occlusion were significantly higher in the CE group (OR 3.066, 95% CI 1.020–9.213, p = 0.046). The bilateral occlusion of fallopian tubes (OR 8.785, 95% CI 1.408–54.818, p = 0.020) rather than unilateral occlusion (OR 2.860, 95% CI 0.893–9.162, p = 0.077) was significantly associated with chronic endometritis. The presence of a hydrosalpinx on one side (OR 7.842, 95% CI 1.279–48.086, p = 0.026) or both sides (OR 9.450, 95% CI 1.037–86.148, p = 0.046) was significantly associated with chronic endometritis. The comparison of CD138-positive HPF counts among the tubal occlusion patients without hydrosalpinx, patients with unilateral hydrosalpinx and patients with bilateral hydrosalpinx were as follows: 1 HPF (50.00% vs. 12.50% vs. 11.11%, p = 0.051), 2 HPF (38.89% vs. 25.00% vs. 22.22%, p = 0.615), ≥3 HPF (11.11% vs. 62.50% vs. 66.67%, p = 0.005). The stage of tubal condition was positively correlated with CD138-positive HPF counts in women with chronic endometritis (r = 0.460, p = 0.001). Conclusion: CE was closely related to the blockage of fallopian tubes and hydrosalpinx. The severity degree of the fallopian lesion condition was associated with inflammation of the endometrium.

Background: Hysterosalpingo-foam sonography (HyFoSy) has gained popularity in the last decades, as it represents a feasible, well-tolerated, and minimally invasive method of evaluation of tubal patency in cases of infertility. The purpose of this study was to communicate the technical tips and tricks based on our experience in performing HyFoSy, with the aim to improve the feasibility, to reduce the pain, and to evaluate pregnancy-obtaining rate after procedure. Methods: Our observational study includes 672 patients from infertile couples who underwent HyFoSy for tubal patency evaluation. During HyFoSy, tubal pathway and patency as well as the level of pain were evaluated. A telephonic questionnaire was conducted in order to assess the pregnancy obtaining rate in the first 3 months and more than 3 months after the procedure. Results: The median age in our group was 33.5 years. Most of our patients (61.16%) underwent HyFoSy in the 8–10 days of the menstrual cycle. Tubal patency was present bilaterally in 86% cases, unilaterally in 11% of patients, and was absent in 3% of cases; 75% of patients related absent or tolerable pain, 17% described HyFoSy as a painful procedure, and 8% experienced extreme pain. After HyFoSy, pregnancy was naturally obtained in 10.86% of cases within the first 3 months after HyFoSy. Conclusions: HyFoSy represents a useful, easy to use, and painless tool in female infertility evaluation and should be considered as a complementary method of the transvaginal ultrasonography, completing the genital tract imaging with information about the hidden part of the standard examination: tubal patency. HyFoSy provides information about patency, caliber regularity, pathway, and occlusion location of the fallopian tubes; therefore, it should be introduced along with transvaginal ultrasound as a first-line infertility exploration method.

There are limited data on how non-infectious risk factors influence tubal patency in women with subfertility. With hormonal shifts influencing tubal secretions, it has been argued that subfertile women with polycystic ovary syndrome (PCOS) have lower tubal patency. In a retrospective study, 216 women, who underwent diagnostic evaluation for PCOS and infertility, were included. Fallopian tube patency was tested using HSG, HyCoSy, and laparoscopic chromopertubation in 171 (79.2%), 28 (13.0%), and 17 (7.9%), respectively. Bilateral patency was found in 193 women (89.4%), unilateral patency in 13 (6.0%) and bilateral occlusion in 10 (4.6%) patients. Women with PCOS phenotypes C (odds ratio, OR 0.179, 95% CI: 0.039–0.828) and D (OR 0.256, 95% CI: 0.069–0.947) demonstrated lower risks for Fallopian tube occlusion. In conclusion, our data suggest that about 5% of infertile women with PCOS also have bilateral tubal occlusion, which seems similar to the rate in non-subfertile women. With 11% of participants having unilateral or bilateral tubal occlusion, this should reassure women with PCOS that their hormonal challenges do not seem to increase their risk for tubal factor subfertility.

Endometriosis seems to have a strong negative effect on female fertility. The aim of this study was to assess the rate of tubal occlusion diagnosed via laparoscopic chromopertubation in infertile women with endometriosis and compare the results to infertile women without endometriosis. In this retrospective cohort study, 275 infertile women with endometriosis and 49 infertile women without endometriosis undergoing diagnostic laparoscopy for primary or secondary infertility with chromopertubation at the Medical University of Vienna between January 2012 and December 2020 have been investigated. During the laparoscopic assessment of tubal patency, significantly more fallopian tubes were occluded in the endometriosis group compared to the control group (25.8 versus 15.3%; p = 0.029). Unilateral and bilateral occlusion was found significantly more often in patients with endometriosis (p = 0.021). In the multivariate analysis, only the rASRM stage (the revised classification of endometriosis by the American Society for Reproductive Medicine) showed a significant association with bilateral occlusion (OR 1.400, 95%CI: 1.018–1.926; p = 0.038). Both a higher rASRM stage (OR 2.181, 95%CI: 1.191–3.995; p = 0.012) and secondary infertility (OR 1.514, 95%CI: 1.156–1.983; p = 0.003) were associated with an increased risk for any kind of fallopian tube occlusion. Endometriosis seems to be associated with an increased risk for fallopian tube occlusion. The rate of tubal occlusion increased significantly with the rASRM stage. Full article

Chlamydia trachomatis IgG antibody testing (CAT) has been used as a screening test for tubal factor infertility (TFI), but as the CAT is only a marker of a past exposure to C. trachomatis and not of late sequelae, the positive predictive value (PPV) of the test is low. The persistence of C. trachomatis in the upper genital tract has been suggested as one of the key mechanisms in the development of TFI. Serum antibodies against C. trachomatis TroA and HtrA, proteins expressed specifically during persistent infection, have been suggested as novel biomarkers for TFI diagnostics. We studied serum IgG antibody responses against C. trachomatis TroA, HtrA and MOMP in 79 subfertile women, of whom 28 had laparoscopically proven TFI. We confirmed that the accuracy of CAT in diagnosing TFI is low, whereas TroA IgG and HtrA IgG are more accurate tests in detecting tubal occlusion and pelvic adhesions. However, the sensitivity and negative predictive value (NPV) of TroA IgG and HtrA IgG are still too low to justify their use as a screening test in clinical practice. Individual immunogenetic profiles combined with TroA and HtrA antibody responses might identify women with the highest risk for developing late complications after C. trachomatis infection.

Objective. To evaluate the diagnostic accuracy of hysterosalpingography in the diagnosis of tubal pathology among infertile patients.
Patients and methods. A prospective cross-sectional study in Kaunas University of Medicine Hospital within the period of 18 months was performed. Consecutive infertile women formed the study group according to defined criteria. Hysterosalpingography was performed in the preovulatory phase of the menstrual cycle. Laparoscopy and dye test was performed within one – three months after hysterosalpingography. General tubal pathology, tubal occlusion, and peritubal adhesions detected at hysterosalpingography were compared with general tubal pathology, tubal occlusion, and peritubal adhesions detected at laparoscopy.
Results. The study population comprised 149 infertile women. The sensitivity of 81.4% and specificity of 47.8% the likelihood ratio of a positive test result of 1.6 and a negative test result of 0.4 for hysterosalpingography while evaluating general tubal pathology was determined. Sensitivity of 84.1% and specificity of 59.1% and likelihood ratios of 2.1 and 0.3, respectively, were calculated, when tubal occlusion was defined as any abnormality of tubal patency. When definition of tubal occlusion was limited to two-sided occlusion, the sensitivity and specificity were 89.5% and 90% and likelihood ratios 9.0 and 0.1, respectively. As a test of peritubal adhesions, hysterosalpingography had sensitivity of 35.5% and specificity of 81.3% and likelihood ratios of 1.9 and 0.8, respectively.
Conclusion. The diagnostic performance of hysterosalpingography in the diagnosis of general tubal pathology and peritubal adhesions is poor. Hysterosalpingography is more accurate in the diagnosis of tubal occlusion. Full article
