Postpartum sexual function; the importance of the levator ani muscle

Women`s sexual function during the postpartum period: A systematic review on measurement tools

BACKGROUND

Sexual health is a critical component of overall well-being, yet discussions around sexual function, especially in the context of postpartum recovery, are often taboo or sidelined. The aim was to review measurement tools assessing women's sexual function/health during the postpartum period.

METHODS

We did a systematic search according to preferred reporting items for systematic reviews and meta-analyses 2020 guidelines in different databases, including PubMed, Web of Science, Scopus, Embase, ProQuest and Open Access Thesis and Dissertations, and Google scholar search engine until June 2023. Also, the reference list of the related reviews has been screened. Eligible studies included observational studies or clinical trials that evaluated women`s sexual function during the postpartum period using existing tools. Data extraction covered study characteristics, measurement tools, and their validity and reliability.

RESULTS

From 3064 retrieved records, after removing duplicates and excluding ineligible studies, and reviewing the reference list of the related reviews, 41 studies were included in this review. Tools measuring sexual function were developed from 1996 to 2017. Sexual activity questionnaire, female sexual function index (FSFI), sexual function questionnaire, short form of the pelvic organ prolapse/urinary incontinence sexual questionnaire, sexual health outcomes in women questionnaire, shorter version of FSFI, and sexual function questionnaire's medical impact scale and Carol scale.

CONCLUSION

Sexual activity questionnaire, FSFI, sexual function questionnaire, short form of the pelvic organ prolapse/urinary incontinence sexual questionnaire, sexual health outcomes in women questionnaire, shorter version of FSFI, sexual function questionnaire's medical impact scale, and Carol scale are valid and reliable measuring tools to assess sexual function or sexual health during postpartum period, which can be used in primary studies according to the study aim and objectives.

The predicting value of the ratio of levator hiatus diameter to fetal head circumference in pregnant women at 37 weeks of gestation in the progression of the second stage of labor and levator ani injury 6 weeks postpartum

Objective

This study investigated the predicting value of the ratio of levator hiatus diameter (LHS) to fetal head circumference (HC) in pregnant women at 37 weeks of gestation in the progression of the second stage of labor and levator ani injury 6 weeks postpartum.

Methods

A total of 120 first-time women who gave vaginal delivery at 37 weeks of pregnancy were selected as the subjects in our hospital during March 2021 to March 2022. The subjects were divided into the second stage of labor > 1 h group and the second stage of labor ≤ 1 h group, according to the delivery time of the second stage of labor. According to the 6-week postpartum follow-up ultrasound examination with or without levator ani injury, they were divided into levator ani injury group and no injury group. All primipara women underwent three-dimensional ultrasonography at 37 weeks of gestation, and the resting LHS, Valsalva LHS, fetal HC and the ratio of resting LHS and fetal HC were compared. The correlation between these factors and the length of the second labor stage was analyzed using Pearson correlation analysis. The value of these factors in predicting labor progression and postpartum levator ani injury was assessed by receiver operating characteristic (ROC) curves.

Results

The resting LHS, Valsalva LHS and the ratio of resting LHS and fetal HC in the levator ani injury group were lower than these in the no injury group, while fetal HC in the levator ani injury group was higher than that in the no injury group (P < 0.05). The resting LHS, Valsalva LHS and the ratio of resting LHS and fetal HC in the second stage of labor > 1 h group were lower than these in the second stage of labor ≤ 1 h group, while fetal HC in the second stage of labor > 1 h group was higher than that in the second stage of labor ≤ 1 h group (P < 0.05). A significant negative correlation was observed between resting LHS/HC and total labor process (=-0.333, P < 0.01). ROC curve analysis showed that the AUCs of resting LHS, Valsalva LHS, HC, and resting LHS/HC ratio in predicting prolongation of the second stage of labor were 0.741, 0.740, 0.702, and 0.843 respectively. Besides, the AUCs of resting LHS, Valsalva LHS, HC, and resting LHS/HC ratio in predicting the total labor process were 0.657, 0.684, 0.768, and 0.836 respectively. The AUCs of resting LHS, Valsalva LHS, HC, and resting LHS/HC ratio in predicting postpartum levator ani muscle injury were 0.769, 0.773, 0.747, and 0.885 respectively.These results suggested that the ratio of resting LHS and fetal HC may have certain clinical value in predicting levator ani injury in pregnant women.

Conclusion

LHS, fetal HC and the ratio of resting LHS and fetal HC are significantly correlated with labor progression and postpartum levator ani injury, which have certain value in predicting labor progress and postpartum levator ani injury. Therein, the ratio of resting LHS and fetal HC has the highest predictive value, and early detection of the ratio of resting LHS and fetal HC is helpful to guide the selection of appropriate delivery mode.

Quality of Life and Sexual Satisfaction in the Early Period of Motherhood-A Cross-Sectional Preliminary Study

The aim of the study was to assess the impact of breastfeeding-related fatigue and family support on the sexuality and quality of life of mothers during early motherhood. A cross-sectional preliminary study was conducted between 1 October 2021 and 15 May 2022 in 65 women being in early postpartum period. We used the authors' questionnaire developed for the purposes of the study; the Sexual Satisfaction Scale for Women-SSS-W; the Mell-Krat scale for women; and the General Health Questionnaire-GHQ28. A significant negative correlation was found between the age of the patients and the reduction in somatic symptoms (GHQ28 questionnaire) (r = -0.315, p = 0.011). Women working professionally achieved significantly higher results in the SSS-W contentment category (r = 0.313, p = 0.014). Frequent sexual activity reduced disorders in social functioning (the GHQ28 questionnaire) (r = -0.107, p = 0.283). Women who breastfed up to 5 times a day (p = 0.033) reached significantly higher SSS-W scores in terms of communication. The partner's help significantly contributed to higher sexual satisfaction in the aspect of compatibility (p = 0.004) and the overall level of satisfaction determined with the SSS-W questionnaire (p = 0.016). The presented study suggests that older mothers who are employed and supported by a partner have a higher level of contentment, sexual satisfaction and quality of life.

A review of levator ani avulsion after childbirth: Incidence, imaging and management

Key Content • Levator ani muscle (LAM) avulsion injury occurs occultly during childbirth, most commonly during operative vaginal deliveries. • Injuries of levator ani have long term sequelae for pelvic floor health. As life expectancy increases the burden of disease upon urogynaecology services will need to be considered. • Diagnosis of this condition can be difficult as there is no agreed 'gold standard' imaging modality. • There is no consensus regarding surgical management of LAM avulsion. Learning objectives • Review anatomy and function of levator ani muscle • Identify the risk factors for levator ani avulsion injury • Role of imaging to appropriately identify LAM injury and current management options including appropriate follow up • Management of subsequent pregnancy following LAM avulsion Ethical issues • Is there value to the patient in diagnosing levator ani avulsion when there is no recommended treatment for these injuries?

Ultrasonography Comparison of Pelvic Floor and Abdominal Wall Muscles in Women with and without Dyspareunia: A Cross-Sectional Study

Pelvic floor hypertonicity and narrowing of the levator ani hiatus is traditionally assumed in women with dyspareunia and considered a therapeutical target by physical therapists. However, accurate pre-treatment assessment of pelvic floor muscles is difficult to perform in clinical sites. In addition, the abdominal musculature has not been evaluated in this population, despite its relationship with pelvic floor disfunctions. The purpose of this study was to determine the existence of differences in the length of the anteroposterior diameter of the levator ani hiatus (APDH), the thickness of the abdominal wall musculature and the interrecti distance (IRD) in subjects with dyspareunia compared to a control group. A cross-sectional observational study was designed using ultrasound imaging to measure the APH, the thickness of the abdominal musculature—rectus abdominis (RA), transverse abdominis (TrAb), internal oblique (IO), external oblique (EO)—and IRD at rest and during contraction. Thirty-two women were recruited through advertising and social webs and divided into two groups: dyspareunia (n = 16) and no dyspareunia (n = 16). There were no statistically significant differences (p < 0.05) in RA, TrAb, OI and OE muscle thickness. No differences in APH or in supraumbilical and infraumbilical IRD were found. The findings of this study suggest that the relationship between the abdominal structure/levator ani hypertonia and dyspareunia remains uncertain.

New Method for Genital Aesthetic Surgery: An Easy-To-Learn Two-Step Approach With Acellular Dermal Matrix (ADM)

BACKGROUND

Vaginal laxity, usually accompanied with prolapse symptoms, affects women's sexual satisfaction and quality of life. Vaginal tightening surgery aims to reinforce the peri-vaginal muscle strength and restore the normal vaginal anatomy.

OBJECTIVES

The objective of this study was to introduce a new surgical approach with vaginal tightening using acellular dermal matrix (ADM).

METHODS

In this retrospective study, we analyzed data from 80 patients with vaginal laxity who underwent surgery from April 2017 to April 2021. Three-dimensional transvaginal ultrasound (3D-TVS) and the Female Sexual Function Index (FSFI) were evaluated among the patients.

RESULTS

The mean age of the patients was 44.6 years. The mean patient follow-up was 13.2 months. No infection, rectovaginal fistula, or implant explantation occurred. 3D-TVS demonstrated a significant reduction of introital diameter on a maximum Valsalva maneuver (2.3 cm vs. 4.1 cm; p<0.05) and the reconstruction of acute vaginal angulation. FSFI orgasm subscore increased significantly.

CONCLUSIONS

Vaginal tightening with ADM is a minimally invasive surgery with safety and efficacy for patients with vaginal laxity.

Pelvic floor dysfunction one year after first childbirth in relation to perineal tear severity

The aims of this study were to evaluate pelvic floor dysfunction symptoms one year after delivery and investigate whether adverse functional outcomes after childbirth were related to the degree of perineal injury. A prospective cohort of 776 primiparas were included. Self-reported pelvic floor function data were obtained using a web-based questionnaire. Women with no/first-degree injuries, second-degree injuries, third-/fourth-degree injuries (obstetric anal sphincter injury, OASI) and cesarean section were compared. A total of 511 women (66%) responded. Second-degree tears were a risk factor for stress incontinence (aOR 2.6 (95% CI 1.3–5.1)). Cesarean section was protective against stress incontinence (aOR 0.2 (95% CI 0.1–0.9)). OASI was a risk factor for urge incontinence (aOR 4.8 (95% CI 1.6–15)), prolapse (aOR 7.7 (95% CI 2.1–29)) and pelvic pain (OR 3.3 (95% CI 1.1–10)). Dyspareunia was reported by 38% of women, 63% of women in the OASI group (aOR 3.1 (95% CI 1.1–9.0)). Women with OASI reported that the injury affected daily life (OR 18 (95% CI 5.1–59)). Pelvic floor dysfunction is common after childbirth, even in women with moderate injury. Women with OASI had significantly higher risks of symptoms of prolapse, urge urinary incontinence, pain, dyspareunia and impacts on daily life.

Surgical Repair of the Genital Hiatus: A Narrative Review

INTRODUCTION AND HYPOTHESIS

An enlarged genital hiatus (GH) is associated with the development of prolapse and may be associated with prolapse recurrence following surgery; however, there is insufficient evidence to support surgical reduction of the GH as prophylaxis against future prolapse. The objective of this review is (1) to review the association between GH size and pelvic organ prolapse and (2) to discuss the existing literature on surgical procedures that narrow the GH.

METHODS

A literature search was performed in the PubMed search engine, using the keyword "genital hiatus." Articles were included if they addressed any of the following topics: (1) normative GH values; (2) associations between the GH and prolapse development or recurrence; (3) surgical alteration of the GH; (4) indications, risks or benefits of surgical alteration of the GH.

RESULTS

An enlarging GH has been observed prior to the development of prolapse. Multiple studies show that an enlarged pre- and/or postoperative GH is associated with an increased risk of recurrent prolapse following prolapse repair surgery. There are limited data on the specific risks of GH alteration related to bowel and sexual function.

CONCLUSIONS

GH size and prolapse appear to be strongly associated. Because GH size appears to be a risk factor for pelvic organ prolapse, the GH size should be carefully considered at the time of surgery. Surgeons should discuss with their patients the risks and potential benefits of additional procedures designed to reduce GH size.
