This study evaluates the impact of fresh versus frozen microTESE on the progression to intra‐cytoplasmic sperm injection (ICSI) cycles, focusing on sperm motility.Materials and MethodsWe conducted a retrospective analysis of microTESE procedures at a major medical centre from 2007 to 2021, excluding cases of obstructive azoospermia and cryptozoospermia. Patients were divided into two groups: fresh microTESE (Group FR) and frozen microTESE (Group FZ). Sperm motility was assessed, and ICSI outcomes were compared between groups.ResultsOut of 128 microTESE procedures on 113 NOA patients, 31 were fresh and 97 were frozen. Sperm was found in 67.7% of fresh cases and 45.3% of frozen cases. In fresh cases, 85.7% had motile sperm for ICSI, whereas in frozen cases, 81.8% had motile sperm initially, but only 52.7% retained motility post‐thaw.ConclusionsOur findings indicate a significant drop in motile sperm availability for ICSI in frozen microTESE cases compared to fresh ones. This suggests a potential advantage of fresh microTESE for certain couples, despite the logistical challenges, highlighting the need for careful patient selection and counselling.","PeriodicalId":8599,"journal":{"name":"Australian and New Zealand Journal of Obstetrics and Gynaecology","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142256687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Websites were assessed for Health on the Net certification. Readability was assessed using a readability calculator, and understandability/actionability of website and video information was assessed using the Patient Education Materials Assessment Tool (PEMAT) for Print or Audiovisual Materials.ResultsLess than one‐third (24%) of the websites were certified for quality. The median readability score for the websites was grade 9 and the websites and videos both rated highly for understandability and actionability. The median understandability score for the website information was 87%, and the median actionability score was 71%.

The device was available in 17/21 units represented. The 108 users of the device reported this was most commonly on collegial advice (63%) or after personal experience of a difficult delivery (33%) and most (80%) believed it reduced maternal morbidity. Only around one‐third of the 130 respondents who had heard of the device agreed there was adequate research demonstrating its efficacy for maternal (36%) and neonatal (30%) morbidity. The majority reported they would change practice in response to a randomised trial, although they were more likely to start use (81% of current non‐users) than stop (53% of users).

Overactive bladder (OAB) is estimated to affect 11.8% of women worldwide, causing diminished quality of life. Lifestyle modifications, muscarinic receptor antagonist and beta‐adrenoreceptor agonist remain the mainstay of treatment but are limited by their efficacy and adverse effects. Access to third‐line therapies of intravesical botulinum toxin type A or sacral neuromodulation is limited by their invasive nature. Percutaneous tibial nerve stimulation (PTNS) has emerged as a non‐invasive treatment option for OAB.MethodsThis study was a single‐arm trial of women requesting third‐line treatment for OAB. The primary treatment outcome was patient‐reported visual analogue score (VAS) improvement of at least 50%. Secondary outcome measures were Urinary Distress Inventory Short Form (UDI‐6) score and two‐day bladder diary. Patients also provided feedback on adverse effects encountered.ResultsIn the 84 women recruited, initial treatment protocol showed a success rate of 77.2% among those who completed treatment based on VAS, with a statistically significant improvement in mean UDI‐6 score of 20.13 (<jats:italic>P</jats:italic> &lt; 0.01, standard deviation: 12.52). Continued success following tapering protocol of 60.8% and a mean maintenance protocol of 14.2 months was achieved.

Further randomised controlled trials to evaluate the optimal treatment protocol are warranted to establish a standardised regime.","PeriodicalId":8599,"journal":{"name":"Australian and New Zealand Journal of Obstetrics and Gynaecology","volume":"244 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140626505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
