Ultrasound findings in infertile women with endometriosis: evidence of concomitant uterine disorders

Recurrence of Uterine Fibroids After Conservative Surgery or Radiological Procedures: a Narrative Review

The present narrative review aims to discuss the available data on the incidence and the risk factors of uterine fibroids (UFs) recurrence after different types of conservative surgical or radiologic procedures in women wishing to preserve their uterus. UFs are the most common benign tumors in women all over the world. Clinical presentation, including abnormal uterine bleeding (AUB), pelvic pain, bulky symptoms, and infertility affect patients' quality of life, and a large variety of conservative treatments are available especially for those with desire of pregnancy. Fertility sparing surgery, by either laparoscopy, hysteroscopy or laparotomy, or radiological interventions (uterine artery embolization, high-intensity focused ultrasound or magnetic resonance-guided focused ultrasound), are the most common therapeutic approaches. However, the genetic or acquired predisposition to UFs remain despite the treatments, and the recurrences are frequently described in a large percentage of patients. The most relevant risk factors for recurrence of UFs are young age at the first surgery, incomplete fibroid resection, the presence of multiple lesions, an enlarged uterus, and the coexistence with other pelvic diseases. The discussion on the possible medical strategy to reduce the recurrence is an open field of clinical investigation, in particular by using hormonal drugs.

Epidemiology of infertility in women with endometriosis

Endometriosis is a benign, chronic, inflammatory condition affecting up to 10 % of women and characterised by the presence of glands and stroma tissue outside the uterus. Epidemiological and clinical studies demonstrate a consistent association between endometriosis and infertility. However, this relationship is far to be clearly understood and several mechanisms are involved. Available data show that patients with endometriosis have an increased estimated risk of infertility between two and four times compared with the general population. On the other hand, the probability of patients with infertility to have endometriosis is reported up to about 50 % of the cases. Future studies should aim to better elucidate the mechanisms behind endometriosis-associated infertility in order to offer the more appropriate and tailored management for the patients.

Shorter Anogenital Distance in Women with Ovarian Endometriomas and Adenomyosis, but Not Uterine Leiomyomas

We investigated whether anogenital distance (AGD) is associated with adenomyosis, endometriosis and uterine leiomyomas (UL, also called uterine fibroids). We recruited 81 women with UL, 105 with ovarian endometrioma (OE), 116 with adenomyosis, 28 with both adenomyosis and UL, and 100 control subjects with other acquired gynecological conditions but not endometriosis, adenomyosis, UL, or polycystic ovarian syndrome. Measurements from the anterior clitoral surface to the center of the anus (AGDAC), from the tip of the clitoris to the center of the anus (AGDACt), and from the posterior fourchette to the center of the anus (AGDAF) were made in all subjects. Multiple regression was performed to estimate the association between AGDs and presence of OE, adenomyosis, and UL while controlling for possible confounding factors. We found that, compared with controls, women with OE and adenomyosis, but not UL, had significantly shorter AGDAF, but not AGDAC. However, the amount of variance that could be explained by the disease status is rather moderate, suggesting that factors other than disease status, bodyweight and height were also responsible for AGD. Thus, prenatal exposure to reduced levels of androgen may increase the risk of developing endometriosis and adenomyosis. However, other factors may also contribute to the pathogenesis of endometriosis and adenomyosis.

Fertility return after hormonal contraceptive discontinuation and associated factors among women attended Family Guidance Association of Ethiopia Dessie model clinic, Northeast Ethiopia: A cross-sectional study

BACKGROUND

Women who use hormonal contraception face delayed return of fertility upon discontinuation. There was limited evidence of fertility return after hormonal contraceptive discontinuation in the study area. Hence this study assessed fertility return after hormonal contraceptive discontinuation and associated factors among pregnant women attending Family Guidance Association Ethiopia (FGAE) Dessie model clinic, Northeast Ethiopia, 2019.

METHODS

A cross-sectional study was conducted on 423 samples selected by using systematic random sampling. Data were collected by face-to-face interview using a pretested and structured questionnaire and reviewing client records. Data were entered using Epi Data version 3.1 and analyzed using SPSS version 23. Both bi-variable and multivariable binary logistic regressions were used to identify predictors of delayed fertility return. Adjusted odds ratio (AOR) along with a 95% Confidence Interval (CI) was used to measure the strength and the direction of the association and statistical significance was declared at a P-value less than 0.05.

RESULT

The proportion of fertility return among currently pregnant women after discontinuation of any hormonal contraceptive methods was 88.6% (95% CI; (85.6%-92%)). The proportion of fertility return among Depo-Provera, implant, Intrauterine Contraceptive Device (IUCD), and Oral Contraceptive Pill (OCP) users was 75%, 99.1%, 100%, and 97.8% respectively. Age, (AOR = 5.37, (95% CI; (1.48, 13.6)) and using Depo-Provera (AOR = 4.82, 95% CI; (1.89, 14.2)) had a significant association with delayed fertility return.

CONCLUSIONS

The proportion of fertility return among women after discontinuation of any hormonal contraceptive methods was high. Age and using Depo-Provera had a positive association with delayed fertility return. This study recommends a contraceptive counseling approach that addresses concerns about delay in the return of fertility after hormonal contraceptive discontinuation to avoid confusion among family planning users.

The impact of small and asymptomatic intramural and subserosal fibroids on female fertility: a case-control study

STUDY QUESTION

Do small and asymptomatic intramural and subserosal uterine fibroids affect female fertility?

SUMMARY ANSWER

Small and asymptomatic fibroids that do not encroach the endometrial cavity appear to not markedly affect female fertility.

WHAT IS KNOWN ALREADY

The available evidence on uterine fibroids and fertility is limited. Most information has been obtained in IVF settings by comparing the success in women affected and not affected by fibroids. These studies have shown a detrimental effect of submucosal and possibly intramural fibroids. However, this study design provides information only on embryo implantation, not on female fertility in general.

STUDY DESIGN SIZE DURATION

A retrospective observational case-control study on 200 women whose partner was diagnosed with severe male infertility and 200 women with unexplained infertility was conducted. If the null hypothesis (that fibroids do not affect fertility) is valid, one would expect a similar prevalence of fibroids in the two study groups. Conversely, if fibroids do impact fertility, one would expect a higher prevalence among women with unexplained infertility. The study was carried out at the Infertility Unit of the Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico covering a 5-year period between January 2014 and June 2020.

PARTICIPANTS/MATERIALS SETTING METHODS

We retrospectively recruited women seeking pregnancy whose partner was repeatedly documented to have a sperm concentration below 1 million/ml and matched them by age and study period to a group of women with unexplained infertility. The latter group of women was considered as a case group (infertile subjects), while the former group of women was considered as a control group (reflecting the general female population). Women with fibroids could be included in both study groups; only those with submucosal lesions were excluded.

MAIN RESULTS AND THE ROLE OF CHANCE

Fibroids were diagnosed in 31 women (16%) with unexplained infertility and in 32 women (16%) with severe male factor infertility. The adjusted odds ratio of carrying fibroids in women with unexplained infertility was 0.91 (95% CI: 0.52-1.58). Subgroup analyses according to number, dimension and location of fibroids failed to highlight an increased risk of infertility in any group.

LIMITATIONS REASONS FOR CAUTION

This is a retrospective study and some inaccuracies in fibroids detection cannot be ruled out. Moreover, the relatively small sample size hampers robust subgroup analyses. Even though we excluded women with patent causes of infertility, some women with specific causes of infertility could have been included among controls (yet are expected to account for <10% of the group).

WIDER IMPLICATIONS OF THE FINDINGS

This study suggests that small fibroids that do not encroach the endometrial cavity do not markedly affect female fertility. This information is clinically relevant when counseling infertile women with small fibroids and an otherwise unremarkable diagnostic work-up. Surgery may still be considered but only in selected cases.

Endometriosis-associated infertility: From pathophysiology to tailored treatment

Despite the clinically recognized association between endometriosis and infertility, the mechanisms implicated in endometriosis-associated infertility are not fully understood. Endometriosis is a multifactorial and systemic disease that has pleiotropic direct and indirect effects on reproduction. A complex interaction between endometriosis subtype, pain, inflammation, altered pelvic anatomy, adhesions, disrupted ovarian reserve/function, and compromised endometrial receptivity as well as systemic effects of the disease define endometriosis-associated infertility. The population of infertile women with endometriosis is heterogeneous, and diverse patients' phenotypes can be observed in the clinical setting, thus making difficult to establish a precise diagnosis and a single mechanism of endometriosis related infertility. Moreover, clinical management of infertility associated with endometriosis can be challenging due to this heterogeneity. Innovative non-invasive diagnostic tools are on the horizon that may allow us to target the specific dysfunctional alteration in the reproduction process. Currently the treatment should be individualized according to the clinical situation and to the suspected level of impairment. Here we review the etiology of endometriosis related infertility as well as current treatment options, including the roles of surgery and assisted reproductive technologies.

Adenomyosis and fertility: does adenomyosis impact fertility and does treatment improve outcomes

PURPOSE OF REVIEW

Adenomyosis has recently been associated with infertility. Relief of bleeding and pain has been demonstrated with medical and surgical therapy. Less is known about reproductive outcomes after treatment.

RECENT FINDINGS

Imaging findings during infertility evaluation can be suggestive of adenomyosis without pathologic evaluation. Among women with infertility undergoing assisted reproductive technologies (ART), adenomyosis is associated with lower live birth rates and clinical pregnancy rates. Treatment with gonadotropin releasing hormone (GnRH) modulators prior to frozen embryo transfer may increase the live birth rate and clinical pregnancy rate among women with adenomyosis. Pregnancy has been documented following image-guided adenomyosis ablation; however, the reproductive impact is not well established. Pregnancy following excisional procedures appears to be well tolerated, although may carry a higher risk of uterine rupture compared with pregnancy following myomectomy. It is not clear if ablative therapy or resection increases pregnancy rates.

SUMMARY

Adenomyosis is associated with lower embryo implantation rates and ongoing pregnancy rates. Adenomyotic changes in the uterus can be seen by ultrasound and MRI. GnRH modulators may be useful for women with adenomyosis undergoing ART. Additional prospective data is warranted to determine the optimal medical or surgical therapy for women with adenomyosis desiring conception.Video abstract Supplementary digital content, http://links.lww.com/COOG/A78.

Morphological Uterus Sonographic Assessment Criteria for Adenomyosis Diagnostic: A Case Report

BACKGROUND : The MUSA (Morphological Uterus Sonographic Assessment) statement is a consensus statement on terms, definitions and measurements that may be used to describe and report the sonographic features of the myometrium using gray-scale sonography, color/power Doppler and three-dimensional ultrasound imaging. MUSA Adenomyosis ultrasound features : Asymmetrical thickening, fan shape shadowing, cyst, hyperechoic island, Echogenic sub endometrial lines and buds, trans lesion vascularity, Irregular junctional zone, Interrupted junctional zone. Classification and descriptions of the MUSA criteria for adenomyosis are presented : location, classification (diffuse/focal), cystic, layer involvement (type), extent, size of the lesion. 

Sonographic Signs of Adenomyosis in Women with Endometriosis Are Associated with Infertility

We compared the prevalence of ultrasound signs of adenomyosis in women with endometriosis who underwent surgery to those who were managed conservatively. This was a retrospective study of women evaluated at a tertiary endometriosis referral center who underwent 2D/3D transvaginal ultrasound. Adenomyosis diagnosis was based on the presence of at least three sonographic signs. The study group subsequently underwent laparoscopic surgery while the control group continued conservative management. Statistical analysis compared the two groups for demographics, symptoms, clinical data, and sonographic findings. The study and control groups included 244 and 158 women, respectively. The presence of any, 3+, or 5+ sonographic signs of adenomyosis was significantly more prevalent in the study group (OR = 1.93–2.7, p < 0.004, 95% CI; 1.24–4.09). After controlling for age, for all findings but linear striations, the OR for having a specific feature was higher in the study group. Women in the study group with ≥ 5 sonographic signs of adenomyosis had more than twice the risk of experiencing infertility (OR = 2.31, p = 0.012, 95% CI; 1.20–4.45). Sonographic signs of adenomyosis are more prevalent in women with symptomatic endometriosis who underwent surgery compared with those who continued conservative management. Women with 5+ findings have a significantly increased risk of infertility. Adenomyosis on ultrasound should be considered in the management decisions regarding these patients.

Uterine involvement by endometriosis: Sonographic features from elusive findings to apparent adenomyosis

OBJECTIVE

The primary aim of this study is to investigate whether there are any minor sonographic uterine findings, not typical for adenomyosis, in endometriosis patients. The secondary objective is to determine the prevalence of sonographic features of adenomyosis in an infertile population with endometriosis.

STUDY DESIGN

The investigation was of 291 infertile women with endometriosis, either manifesting endometrioma (OMA) or diagnosed through laparoscopy, who were investigated for two-dimensional transvaginal sonographic (2D-TVS) features of adenomyosis. These patients were grouped as either having endometriosis with adenomyosis (EwA,n = 121) or without adenomyosis (EwoA, n = 170). Additionally, patients without both endometriosis and 2D-TVS features of adenomyosis constituted the control group (n = 170).

RESULTS

At least one 2D-TVS feature of adenomyosis was detected in 41.6 % (n = 121) of women with endometriosis. Asymmetrical myometrial thickening of uterine walls (57.9 %), hyperechogenic islands (47.1 %), and fan-shaped shadowing (46.9 %) were relatively more prevalent 2D-TVS findings among EwA patients. Multiple OMA (p = 0.038), OMA ≥ 4 cm (p = 0.034), and total OMA volumes were found to be higher (p = 0.004) in the EwA group. Additionally, uterine volumes were found to be 96.7 cm³, 73.0 cm³, and 64.2 cm³ in the EwA, EwoA, and control groups, respectively (EwA vs EwoA, p < 0.001; EwoA vs control, p <0.001). Multivariate linear regression analysis revealed that the presence of endometriosis was independently associated with an increase in uterine volume (β = 0.243, p < 0.001).

CONCLUSION

A stepwise and statistically significant volume increase from the control group to the EwoA and then to the EwA group may reflect a spectrum of uterine involvement in endometriosis. This might indicate that many uterine endometriosis cases are still hidden from view, possibly demonstrating an "iceberg phenomenon".

Comorbidities and Quality of Life in Women Undergoing First Surgery for Endometriosis: Differences Between Chinese and Italian Population

An observational cross-sectional study was conducted in a group (n = 371) of fertile age women with endometriosis, by administering a structured questionnaire, in order to evaluate the incidence of gynecological and systemic comorbidities and the impact on quality of life (QoL) in two different groups of Italian and Chinese patients affected by endometriosis. Chinese (n = 175) and Italian (n = 196) women were compared regarding systemic (inflammatory, autoimmune, and mental) and gynecological comorbidities, pain symptoms, and QoL, by using the Short Form 12 (SF-12). Italian patients resulted younger at the diagnosis and suffered more frequently from severe pain than Chinese ones. Deep infiltrating endometriosis (DIE) and mixed phenotypes were more frequent in Italian patients, whereas ovarian (OMA) and superficial endometriosis (SUP) were more common in the Chinese. The Italian group showed more systemic comorbidities, and those disorder were already present before the diagnosis of endometriosis. Furthermore, the Italian group showed lower SF-12 physical and mental scores, suggesting a worse health-related QoL in Italian endometriotic patients. A number of differences has been observed between Italian and Chinese women with endometriosis in terms of comorbidities and QoL, which may be related to the ethnicity, the different health system organization and the social and cultural background.

Comparing the effects of alcohol sclerotherapy with those of surgery on anti-Müllerian hormone and ovarian reserve after endometrioma treatment. A prospective multicenter pilot cohort study

STUDY OBJECTIVE

To compare the effects of ultrasound-guided aspiration and ethanol sclerotherapy with those of laparoscopic surgery on anti-Müllerian hormone (AMH) levels and ovarian reserve in benign-appearing ovarian endometrioma.

DESIGN

A prospective, cohort pilot study.

SETTING

Multiple centers, Spain.

PATIENTS

Forty patients with a suspected ovarian endometrioma with a maximum diameter of 35-100 mm. Serum hormonal concentrations were analyzed in 26 of these women.

INTERVENTIONS

Two groups: one that received US-guided aspiration plus alcohol sclerotherapy (n = 16) and the other that underwent laparoscopic cystectomy (n = 10).

MEASUREMENTS AND MAIN RESULTS

We studied serum hormonal concentrations (AMH, FSH and 17-β-estradiol) and antral follicle counts (AFC) in each patient at baseline, and after the procedures and pregnancies. No differences were found when comparing AMH and FSH concentrations before and after each procedure. 17-β-estradiol concentrations were significantly increased after alcohol sclerotherapy (p < 0.001). AFC recovery after 6 months seemed to be higher after sclerotherapy than after surgery. Three patients became pregnant in the sclerotherapy group.

CONCLUSION

This pilot study indicated that alcohol sclerotherapy preserves fertility in patients with endometriomas better than surgery, with significant increases in serum estradiol concentrations, possible AFC recovery and spontaneous pregnancies observed in the patients after sclerotherapy.

Epidemiology of Adenomyosis

Adenomyosis, characterized by the presence of endometrial glands and stroma within the myometrium, can have a substantial impact on the quality of women's lives. Despite this, the epidemiologic research on this condition lags considerably behind that of other noncancerous reproductive health conditions. The lack of progress and knowledge is due in part to the challenges in designing valid epidemiologic studies, since the diagnosis of adenomyosis historically has been limited to the examination of uterine specimens from hysterectomy. This review describes the available data on the frequency of this condition and the epidemiologic investigation thus far into the risk factors for disease-highlighting the methodologic and inference challenges primarily around study sample selection. We conclude with providing recommendations for approaches to future epidemiologic study that capitalize on the advancements in imaging technology to detect adenomyosis and provide a fuller picture of the occurrence and risk factors for disease.
