A prospective cohort study of assisted bladder emptying following primary cloacal repair: The Children's National experience.

INTRODUCTION/BACKGROUND: Although the combination of bladder dysfunction and upper tract anomalies puts patient with cloaca at risk for renal disease, the rarity of this condition makes it difficult to study empirically. As a high-volume center, we uniquely capture bladder function outcomes following our growing number of cloacal repairs. OBJECTIVE: 1) Describe the rates of incomplete bladder emptying following primary cloacal repair (at 2-3 months after repair and last follow up), and 2) identify clinical factors associated with assisted bladder emptying. STUDY DESIGN: We performed a prospective cohort study of patients undergoing primary cloaca repair by our Children's National Colorectal Center team between 2020 and 2021. The primary outcome was assisted bladder emptying at 2-3 months postoperatively and last visit. Covariables included preoperative characteristics (cloacagram measurements), ARM complexity (moderate = common channel [CC] <3-cm, severe = CC ≥ 3-cm), vesicoureteral reflux (VUR) status, sacral ratio (good ≥0.7, intermediate 0.7-0.4, poor ≤0.4), spinal cord status, means of preoperative bladder emptying, and operative details (age at repair, repair type, & concomitant laparotomy). RESULTS: Eighteen participants were eligible. A majority had moderate cloaca (78%), VUR (67%), spinal cord abnormalities (89%), and good sacral ratios (56%). Preoperatively, 10 patients were diapered for urine and 8 had assisted bladder emptying. Surgical repairs were performed at a median age of 8 months (range 4-46). Nine (50%) patients underwent urogenital separation (UGS), eight (44%) total urogenital mobilization, and 1 (6%) perineal sparing posterior sagittal anorectoplasty with introitoplasty. Exploratory laparotomy was performed in 7 (39%) patients. At 2-3 months, 7 patients were voiding and 11 required assisted bladder emptying. Median length of long-term follow up was 12 months (range 5-25), and 8 patients were voiding and 10 required assisted bladder emptying. Postoperative need for assisted bladder emptying was significantly associated with assisted bladder emptying preoperatively, a shorter urethra and increasing common channel length, UGS and exploratory laparotomy. Spinal cord imaging findings were not associated. DISCUSSION: Bladder emptying following cloaca repair is likely a result of congenital function and surgical effects. Indeed, increasingly cloaca complexity requiring UGS and laparotomy was associated with both pre- and post-operative assisted bladder emptying. The lack of association with spinal cord imaging may reflect a divergence between anatomy and function. CONCLUSION: Approximately half of patients required assisted bladder emptying in this study. Associated factors included urethral and common channel length, the need for assisted bladder emptying preoperatively, the type of surgical approach and additional laparotomy. Being diapered with seemingly normal voiding prior to surgery did not guarantee normal bladder function postoperatively.

Los factores causantes del acortamiento de pene después de la cirugía con plicatura en pacientes con incurvación peneana congénita / The factors that cause penile shortening after plication surgery in patients with congenital penile curvature

Objetivo La incurvación peneana congénita se define como la incurvación del pene en ausencia de patología uretral o peneana. Nuestro objetivo es evaluar los factores causantes del acortamiento del pene después de la plicatura en pacientes con incurvación peneana congénita. Métodos Entre noviembre de 2010 y diciembre de 2020 revisamos de forma retrospectiva a los pacientes con incurvación peneana congénita que se sometieron a una cirugía mediante técnica de plicatura de la túnica albugínea. Antes del procedimiento, se registró la edad de los pacientes, la ubicación y los grados de la desviación y la longitud del pene. Tras el tratamiento se midió y registró de nuevo la longitud del pene. Se registraron los resultados de los períodos inicial y final. Resultado Se realizó cirugía con plicatura en 130 pacientes. La media de edad era de 24 años. Setenta y seis pacientes tenían incurvación ventral, 22 dorsal y 32 lateral. El acortamiento medio de la longitud del pene en aquellos pacientes con incurvación inferior a 30° fue: ventral 8-16 mm, dorsal 6-13 mm, lateral 5-12 mm. En los pacientes con incurvación superior a 30° fue: ventral 12-22 mm, dorsal 8-20 mm, lateral 2-12 mm. Conclusión El acortamiento del pene después de la plicatura es inevitable. El grado y la dirección de la desviación son factores que afectan la longitud del pene después de la operación. Por lo tanto, los pacientes y sus familiares deben recibir información detallada sobre esta complicación (AU)

Objective Congenital penile curvature is defined as the non-straightness of the penis without any urethral or penile pathology. We aimed to evaluate the factors that cause penile shortening after plication surgery in patients with congenital penile curvature.Methods Between November 2010 and December 2020, we retrospectively reviewed patients with CPC undergoing tunica albuginea plication surgery. Before the procedure, patients’ age, curvature location and degrees, as well as penile length were recorded. After the treatment, penile lengths were measured and recorded again. Early and late period results were recorded. Results plication surgery was performed in 130 patients. The median age was 24 years. Seventy-six patients had ventral curvature, 22 had dorsal curvature, 32 had lateral curvature. Average shortening of penile length in patients with curvature below 30° was: ventral 8-16 mm, dorsal 6-13 mm, lateral 5-12 mm. Patients with curvatures above 30° were: ventral 12-22 mm, dorsal 8-20 mm, lateral 2-12 mm. Conclusion Penile length shortening after plication is inevitable. Curvature degree and direction are factors affecting penile length after surgery. Therefore, patients and relatives should be informed in more detail about this complication (AU)

Disorders of sex development: Challenges in a low-resource country.

AIM: We aimed to identify the challenges in the management of sexual development abnormalities in a low-resource country. METHODS: The study was retrospective from January 2000 to December 2017 based on patient records from two pediatric surgery departments. Epidemiological, clinical, paraclinical, treatment, and outcome data were studied. RESULTS: We collected data on 13 patients (average age = 7.95 years). The sex of rearing was as follows: three females (23%), 10 males (77%). Atypical genitalia other than hypospadias represented the reason for consultation in 92% of the cases. We could not find complete hormonal analyses; testosterone levels were studied in 69.23% of cases. We found the following disorders of sexual development (DSD): four patients with 46,XX karyotype (30.77%), eight patients with 46,XY karyotype (61.53%), and one patient with 46,XX/XY karyotype. Four patients had medical treatment only, four had surgical treatment only, and one patient had medical and surgical treatment. The medical treatment comprised topical administration of androgen. The surgical treatment consisted of feminizing genitoplasty for one patient and masculinizing genital surgeries for two patients. Six of the 13 patients were lost to follow-up. CONCLUSION: The socioeconomic difficulties of the population and the lack of access to basic diagnostic and paraclinical methods, coupled with the negative cultural representations of the pathology, constitute the challenges in the management of DSD in our practice.

Effects of patients' understanding and choice of surgical types on postoperative outcomes of Peyronie's disease: a single-center retrospective study of 108 patients.

Surgical correction can be considered for treating patients with a chronic phase of Peyronie's disease (PD) and persistent penile curvature. In clinical practice, some patients pay too much attention to surgical complications and refuse the recommended feasible surgical types. Meanwhile, they require operations according to their preferences. This study aimed to evaluate the effects of patients' own choice of surgical type on postoperative satisfaction. This retrospective study analyzed data from 108 patients with PD who underwent surgical correction according to doctors' recommendations or patients' own demands. The objective and subjective surgical outcomes were assessed. Patients' understanding of the disease was analyzed using a questionnaire survey. Objective measurements of surgical outcomes, including penile straightening, penile length, and sexual function, in patients who received the recommended surgery, were similar to those in patients who did not accept the recommended surgery. However, subjective evaluations, including erectile pain, discomfort because of nodules on the penis, and decreased sensitivity in the penis, were more obvious in patients who did not follow doctors' recommendations. In addition, a questionnaire survey showed that understanding PD and the purpose of surgery of patients who did not follow doctors' advice were inappropriate, as they did not conform to the principle of treatment. The present study showed that surgical correction seemed to be an objectively effective option in the management of patients in the stable chronic phase of PD. Low patient satisfaction might be related to patients' lack of correct understanding of the disease and its treatment strategy as well as unrealistic expectations.

A New Combined Laparoscopic-Vaginal Lateral Suspension Procedure for the Treatment of Pelvic Organ Prolapse.

OBJECTIVE: To show an original technique of a new combined vaginal-laparoscopic lateral suspension in Hysteropexy with cistocele and rectocele. In recent years, changes in attitudes toward sexuality, psychological value of reproductive organs and the desire to preserve fertility have led to a growing interest in uterine-preserving surgery for Pelvic Organ prolapse. Minimally invasive procedures derived from sacrocolpopexy are considered the gold standard in the treatment of apical Pelvic Organ prolapse. However, dissection at the level of the promontory may be challenging, particularly in obese women and when an anatomical variation exists. This may be associated with rare but serious neurological or ureteral morbidity as well as life-threatening vascular injury. MATERIALS AND METHODS: Stepwise demonstration of the technique with narrated video footage. Local institutional review board was consulted, and this study was exempted from approval. RESULTS: Our technique entails 2 times. During the vaginal time, a polypropylene mesh is fixed to the cervical fascia and the 2 extremities are introduced in the abdominal cavity through the Douglas pouch. During the laparoscopic time, a retroperitoneal tunnel is made along the walls of the lateral abdominal walls; thereafter, each of the 2 extremities of the mesh is passed through the omolateral tunnel and "tension-free" suspended to the abdominal wall. CONCLUSION: Our combined technique may allow a safer approach, reducing the risks of serious complications. Moreover, it leads to a more physiological orientation of the vaginal axis. Further controlled studies are needed to confirm our suggestion.

Robotic Low Anterior Resection and Partial Bladder Resection for Management of Locoregional Endometrial Cancer Recurrence.

OBJECTIVE: To demonstrate a robotic tumor debulking for management of locoregional endometrial cancer recurrence. DESIGN: Case report. SETTING: Tertiary referral center in New Haven, CT. INTERVENTIONS: A 70-year-old patient with a history of stage IB endometrioid endometrial cancer presented with rectal bleeding 3 years after the completion of treatment. A mass involving the distal sigmoid colon/upper rectum and bilateral distal periureteral masses were visualized on imaging. There was no distant metastatic disease. Colonoscopic biopsies were consistent with endometrial cancer recurrence. Because the patient was symptomatic with rectal bleeding and had no distant metastasis, it was recommended that she undergo surgical resection for management of this locoregional recurrence. The patient was placed in reverse Trendelenburg position with a rightward tilt to mobilize the splenic flexure. Once the cephalad aspect of the descending colon mobilization was completed, the patient was placed in Trendelenburg lithotomy position to expose the pelvis. A robot was docked at this point and the pelvic avascular spaces were delineated. A medial-to-lateral approach was used in mobilization of the sigmoid colon mesentery. The left ureter was identified and the sigmoid branches of inferior mesenteric artery were sealed. The descending/sigmoid colon junction was stapled. After complete mobilization of the sigmoid colon, the tumor-free upper rectum was delineated and stapled. Attention was then turned to the distal peri-ureteral masses. The 2-cm mass on the right, which was densely adherent to the distal right ureter, was completely resected after extensive ureterolysis. The resection of the 4-cm mass on the left which involved both the distal left ureter and the bladder dome required an intentional cystotomy and a partial cystectomy to attain negative margins (Supplemental Figure 1). The procedure was continued with the bowel anastomosis. The anvil was introduced through the vagina and was placed into the proximal limb through an antimesenteric incision. An end-to-end tension-free anastomosis was performed and adequate vascularization was confirmed with intravenous indocyanine green. CONCLUSION: Robotic low anterior resection and partial bladder resection were performed without any complications with negative margins. Robotic tumor debulking should be considered in appropriate patients when managing locoregional recurrence of endometrial cancer [1,2].

Full-thickness tissue engineered oral mucosa for genitourinary reconstruction: A comparison of different collagen-based biodegradable membranes.

Tissue engineering is a method of growing importance regarding clinical application in the genitourinary region. One of the key factors in successfully development of an artificially tissue engineered mucosa equivalent (TEOM) is the optimal choice of the scaffold. Collagen scaffolds are regarded as gold standard in dermal tissue reconstruction. Four distinct collagen scaffolds were evaluated for the ability to support the development of an organotypical tissue architecture. TEOMs were established by seeding cocultures of primary oral epithelial cells and fibroblasts on four distinct collagen membranes. Cell viability was assessed by MTT-assay. The 3D architecture and functionality of the tissue engineered oral mucosa equivalents were evaluated by confocal laser-scanning microscopy and immunostaining. Cell viability was reduced on the TissuFoil E® membrane. A multi-stratified epithelial layer was established on all four materials, however the TEOMs on the Bio-Gide® scaffold showed the best fibroblast differentiation, secretion of tenascin and fibroblast migration into the membrane. The TEOMs generated on Bio-Gide® scaffold exhibited the optimal cellular organization into a cellular 3D network. Thus, the Bio-Gide® scaffold is a suitable matrix for engineering of mucosa substitutes in vitro.

Trends in the diffusion of robotic surgery in prostate, uterus, and colorectal procedures: a retrospective population-based study.

This study aimed to propose quantifiable metrics on the adoption lifecycle of robotic-assisted surgery (RAS) within and across prostate, hysterectomy, and colorectal procedures. This was a retrospective population-based cohort study of commonly performed RAS procedures in the US conducted from July 2001 to July 2015. The patients were identified from the Premier Hospital Database using International Classification of Diseases, 9th revision, Clinical Modification codes denoting prostate, uterus, and colorectal procedures. The Diffusion of Innovations theory was applied to percent RAS utilization to determine discrete eras of technology adoption. Overall and by-era patient baseline characteristics were compared between robotic and non-robotic groups. This study included a total of 2,098,440 RAS procedures comprising prostate (n = 155,342), uterus (n = 1,300,046), and colorectal (n = 643,052) procedures. Prostate (76.7%) and uterus (28.9%) procedures had the highest robotic utilization by the end of the study period and appear to be in the last adoption era (Laggard). However, robotic utilization in colorectal procedures (7.5%) was low and remained in the first era (Innovator) for a longer time (15 vs 60 vs 135 months). Whites, privately insured, patients with fewer comorbidities, and those admitted in large teaching hospitals were more likely to undergo RAS in the early study period. AS-associated patient and hospital profiles changed over time, suggesting that selected patient cohorts should be contextualized by overall adoption of a novel medical technology. The time-discretized analysis may also inform patient selection criteria and appropriate timing for clinical study stages proposed by the Idea, Development, Exploration, Assessment, Long-term study-Devices framework.

Efficacy of prostatic urethral lift compared with transurethral resection of the prostate.

This article reviews the prostatic urethral lift (PUL) and its potential benefits and risks compared with transurethral resection of the prostate (TURP). TURP is the traditional procedure for benign prostatic hyperplasia (BPH), and is associated with ejaculatory and erectile dysfunction. PUL is a minimally invasive option, but its efficacy has not been well studied. A literature review indicates that both procedures should be afforded equal consideration, and both have limitations. Further long-term research is needed to establish if PUL is superior to TURP.

Penile Sparing Techniques For Penile Cancer.

Penile cancers are rare malignancies. Traditional surgical options, including partial and total penectomy, can dramatically affect a patient's quality of life and mental health. In select patients, penile sparing techniques (PST) have the potential to remove the primary tumor with comparable oncologic outcomes while maintaining penile length, sexual function, and urinary function. In this review, we aim to discuss the indications, advantages, and outcomes of the various PST currently available for men seeking an organ-preserving option for their penile cancer.

Evolving indications for surgical intervention in patients with differences/disorders of sex development: Implications of deferred reconstruction.

Rare medical conditions are difficult to study due to the lack of patient volume and limited research resources, and as a result of these challenges, progress in the care of patients with these conditions is slow. Individuals born with differences of sex development (DSD) fall into this category of rare conditions and have additional social barriers due to the intimate nature of the conditions. There is also a lack of general knowledge in the medical community about this group of diverse diagnoses. Despite these limitations, progress has been made in the study of effective ways to care for patients who are born with chromosomal or anatomical differences of their internal reproductive organs or external genitalia. Advocacy groups have placed a spotlight on these topics and asked for a thoughtful approach to educate parents of newborns, medical providers, and the adolescents and young adults themselves as they mature.1 There is growing interest in the approaches to surgical reconstruction of the genitalia and the management of internal gonads, specifically the timing of procedures and the indications for those procedures.2 Advocates suggest deferring surgical procedures until the affected individual can participate in the decision-making process. This approach requires a roadmap for addressing the long-term implications of delayed surgical management. Presented here is a review of the specific issues regarding the complex management of the various categories of DSD.

In Support of a Simple Urethrocutaneous Fistula Closure Technique Following Hypospadias Repair.

OBJECTIVE: To evaluate the success rates of a simple posthypospadias urethrocutaneous fistula repair. STUDY DESIGN: We evaluated children who underwent urethrocutaneous fistula closure by means of a simple standard technique in which the fistula tract was dissected to its base and resected and the urethral defect closed with a single layer of continuous sutures and covered with local subcutaneous tissue. No urethral stents or catheters were used, and the patients were discharged on the same day. Excluded were children who underwent fistula repair by a different technique, revision hypospadias repair for fistula, or concomitant meatoplasty for meatal stenosis. Study endpoints were fistula recurrence and the need for further penile surgery other than fistula repair. RESULTS: Seventy-two children underwent 81 repairs. The mean follow-up was 7.9 years. Recurrence occurred in 17 cases (21%). Seven children (9%) underwent penile surgery other than fistula repair, including meatoplasty (n = 5) and re-do hypospadias repair for a diagnosis other than fistula recurrence (n = 2). There was no significant difference in recurrence rate between large and small fistulas, coronal or more proximal fistulas, or children w/wo prior fistula repairs. CONCLUSION: Standard fistula closure solely by adjacent tissues yielded success rates of 79% after long-term follow-up. This repair can be safely offered with the expectation of similar results for a variety of urethrocutaneous fistulas in children.

Perioperative nursing care of a patient with urogenital sinus malformation who underwent vaginal calculus removal and correction: a case report.

Cases of urogenital sinus malformation with a huge calculus are complex and rare. Improper nursing care of these cases can lead to a series of problems. We report here a 23-year-old married woman who was admitted to hospital because of primary amenorrhea and failed sexual intercourse for 5 years. Through combined diagnosis and treatment of radiology, ultrasound, urology, gynecology, and other disciplines, the patient was diagnosed with urogenital sinus malformation, a vaginal calculus, and primary amenorrhea. After full preparation, the patient underwent an operation for extraction of the vaginal calculus, urethroplasty, vaginoplasty, and hysteroscopy. The calculus of the patient was removed and the vagina was returned to its normal anatomy. Patients with urogenital sinus malformation and a huge calculus have complex care requirements and experience a particular state of vulnerability during the diagnostic phase. By establishing good communication with patients and providing proper perioperative nursing, physiological and psychological rehabilitation of these patients can be achieved.

Labial adhesion in a postmenopausal female: A case report.

RATIONALE: Voiding difficulty is more common in males, although it is not uncommon in females. Female voiding difficulty can be caused by iatrogenic, anatomic, and neurogenic factors, and specifically urethra stricture, impaired detrusor contractility, primary bladder neck obstruction, and detrusor-external sphincter dyssynergia. Labial adhesion is a rare cause of female voiding difficulty.The incidence of labial fusion has been reported to be 0.6% to 1.4% in children; however, the incidence in the elderly has yet to be fully elucidated. PATIENT CONCERNS: We present the case of a postmenopausal and sexually inactive 76-year-old female patient who had nearly total vaginal and urethral occlusion due to labial adhesion. She had no underlying diseases and came to our clinic with a 10-month history of voiding difficulty, postmicturition dribbling, and involuntary urinary leakage when getting up. DIAGNOSIS: A genital examination revealed nearly total fusion of the labia minor with only a 3-mm pinhole opening at the posterior end. INTERVENTIONS: Treatment included surgical separation, the local application of estrogen cream, and self-dilatation. She also received an antimuscarinic agent to treat overactive bladder secondary to bladder outlet obstruction which was caused by labial adhesion. OUTCOMES: No surgical complications occurred. Moreover, no labial adhesion or voiding dysfunction was found immediately after the surgery or after 6 months of follow-up. LESSONS SUBSECTIONS: Genital examinations are a basic but very important noninvasive skill for physicians. This case report highlights that genital examinations should be a priority for patients with gynecological or urological symptoms.

[Vesicovaginal fistulas: diagnosis and surgical management]. / Vesikovaginale Fisteln: Diagnostik und operatives Management.

Vesicovaginal fistulas (VVF) represent a detrimental condition causing psychological, physical and social strain on patients. In developed countries they are predominantly the result of pelvic surgery or radiation therapy, whilst obstetric VVF are common in developing countries due to prolonged and complicated births. The majority of VVF require surgical therapy, thus a comprehensive diagnostic workup is needed. Depending on diagnostic characteristics fistula repair can be performed by a transvaginal, transabdominal or minimally invasive approach. Timing of surgery, appropriate interposition of vascularized grafts, optimized postoperative management and surgical expertise are determining factors for successful treatment. This review describes the diagnostic workup and therapeutic management of VVF including various surgical techniques.

Cost Analysis of Vaginal Anti-incontinence Procedures at a Tertiary Care Center.

OBJECTIVE: To compare the cost of 3 vaginal procedures used in the surgical management of stress urinary incontinence (SUI) at 1 tertiary institution. METHODS: The costs of autologous fascial sling (AFS), synthetic mid-urethral sling (MUS), and anterior vaginal wall suspension (AVWS) were analyzed from a prospective long-term database, with follow-up to 5 years after these procedures. Original costing data were obtained for operating room, medical and surgical supplies, pharmacy, anesthesia supplies, and room and bed over 2 consecutive years. Included were complete cost data provided by our institution from Medicare (2012) and private payer insurance. RESULTS: For the year 2013, the AVWS, AFS, and MUS had total median costs of $4513, $5721, and $3311, respectively. Total cost and all subcosts except for pharmacy costs were significantly different for each procedure. AVWS and MUS placement differed from each other regarding the cost of anesthesia and hospital stay, which was higher for AVWS. Compared to AFS, AVWS had significantly lower total costs due to decreased costs associated with operating time, hospital stay, and surgical supplies (P <.0001). At 5 years after these procedures, synthetic slings had less frequent follow-up visits. The most common revision for SUI failure was a bulking agent injection. CONCLUSION: Initial costs of vaginal SUI procedures at our institution fared favorably compared to SUI procedures reported in the contemporary US literature. Long-term costs can vary based on physician preference in follow-up routine and etiology of SUI.

Long-term follow-up of 453 patients with pelvic organ prolapse who underwent transvaginal sacrospinous colpopexy with Veronikis ligature carrier.

Sacrospinous ligament fixation (SSLF) is one of the most utilized surgeries in the management of pelvic organ prolapse (POP). We conducted a large-series study of SSLF in a tertiary center by an experienced urogynecologic team. The 453 women with POP who underwent SSLF at National Taiwan University Hospital in the period from 2002 to 2015 are reviewed. All patients received unilateral SSLF with Veronikis ligature carrier. Concomitant anterior colporrhaphy was performed in 75.3% of the cases and posterior colporrhaphy in 78.6%. The mean operation time was 92.3 ± 31.5 minutes. The intraoperative blood loss was 92.3 ± 91.4 ml. The objective cure rate was 82.5%, and 79 (17.5%) patients recurred. The Kaplan-Meier recurrence-free analysis showed a steep decline during the first postoperative year, and the yearly number of recurrent patients decreased as the follow-up period proceeded. A comparison of the site of recurrence found that anterior compartment prolapse was the most common with 57 cases (12.6%). Paravaginal repair is frequently implemented in the management of recurrent anterior prolapse. In conclusion, SSLF provides excellent support to the apex compartment, and our long-term results show that the anterior compartment is the most commonly encountered type of POP recurrence.

Laparoscopic Ovarian Drilling Improves Endometrial Homeobox Gene Expression in PCOS.

The study was designed to investigate whether laparoscopic ovarian drilling (LOD) of ovaries alters the expression levels of HOXA-10 and HOXA-11 mRNA in the endometrium of infertile women with clomiphene-resistant PCOS. Expression of HOXA-10 and HOXA-11 mRNA in the endometrium obtained before and after LOD during the midsecretory phase was measured. Expression of each gene was evaluated using real-time reverse transcriptase polymerase chain reaction (RT-PCR). Expression levels of HOXA-10 and HOXA-11 mRNA were lower in endometrium of patients with PCOS before LOD compared with fertile controls. But the differences failed to show statistical significance. Compared with fertile subjects, LOD of PCOS ovaries up-regulated endometrial HOXA-10 and HOXA-11 mRNA expression. Fold changes of HOXA-10 and HOXA-11 mRNA after LOD were found to be 4.46 and 4.19, respectively. Fold change increase in HOXA-10 and HOXA-11 mRNA was found to be statistically significant (P < .01, P < .02). There is a receptivity defect in the endometrium of women with PCOS that affects fertility regardless of other causes of infertility. LOD increases endometrial HOXA-10 and HOXA-11 mRNA expressions and improves receptivity in patients with clomiphene-resistant PCOS.
