MATERIALS AND METHODS: A cross-sectional, global, online survey on PE was conducted using a questionnaire developed by an international cohort of experts. Results were analyzed using R version 4.1.2. Additionally, expert recommendations were formulated using a modified Delphi method.
RESULTS: The survey was completed by 264 participants from 41 countries. The majority of respondents were below the age of 45 years and were urologists focusing on andrology and sexual health. PE diagnosis was primarily based (by 61.5%) on an intravaginal ejaculatory latency time of less than one minute. Lifelong PE was the most common category reported (47.7%), and most respondents (84.2%) observed ante-portas PE in less than 25% of cases. Distinguishing PE from erectile dysfunction was challenging for many respondents (60.7%). Diabetes mellitus was the most common comorbidity (17.1%). Pharmacological therapy was the most common treatment method (34.3%), with dapoxetine being the most preferred medication (37.9%). Surgical methods were infrequently used. Emerging treatments like hyaluronic acid gel glans augmentation were favored by only 11.7%. Patient satisfaction was the primary criterion for successful PE treatment (55.9%), and cost was a significant concern for many (35.5%).
CONCLUSIONS: This global survey highlights significant diversity in the diagnostic and treatment strategies for PE. Standard diagnostic criteria are generally accepted, off-label medication is widely used in therapy, and the role of surgery is still controversial. A multi-modal therapy approach, tailored to the patient's specific needs, is favored. Further research into the neurobiology of PE and the development of effective and safe options is crucial for improving the management of PE.
MATERIALS AND METHODS: A 56-item questionnaire survey on NOA diagnosis and management was conducted globally from July to September 2022. This paper focuses on part 1, evaluating NOA diagnosis. Data from 367 participants across 49 countries were analyzed descriptively, with a Delphi process used for expert recommendations.
RESULTS: Of 336 eligible responses, most participants were experienced attending physicians (70.93%). To diagnose azoospermia definitively, 81.7% requested two semen samples. Commonly ordered hormone tests included serum follicle-stimulating hormone (FSH) (97.0%), total testosterone (92.9%), and luteinizing hormone (86.9%). Genetic testing was requested by 66.6%, with karyotype analysis (86.2%) and Y chromosome microdeletions (88.3%) prevalent. Diagnostic testicular biopsy, distinguishing obstructive azoospermia (OA) from NOA, was not performed by 45.1%, while 34.6% did it selectively. Differentiation relied on physical examination (76.1%), serum hormone profiles (69.6%), and semen tests (68.1%). Expectations of finding sperm surgically were higher in men with normal FSH, larger testes, and a history of sperm in ejaculate.
CONCLUSIONS: This expert survey, encompassing 367 participants from 49 countries, unveils congruence with recommended guidelines in NOA diagnosis. However, noteworthy disparities in practices suggest a need for evidence-based, international consensus guidelines to standardize NOA evaluation, addressing existing gaps in professional recommendations.
MATERIALS AND METHODS: A 56-question online survey covering various aspects of the evaluation and management of NOA was sent to specialists around the globe. This paper analyzes the results of the second half of the survey dealing with the management of NOA. Results have been compared to current guidelines, and expert recommendations have been provided using a Delphi process.
RESULTS: Participants from 49 countries submitted 336 valid responses. Hormonal therapy for 3 to 6 months was suggested before surgical sperm retrieval (SSR) by 29.6% and 23.6% of participants for normogonadotropic hypogonadism and hypergonadotropic hypogonadism respectively. The SSR rate was reported as 50.0% by 26.0% to 50.0% of participants. Interestingly, 46.0% reported successful SSR in <10% of men with Klinefelter syndrome and 41.3% routinely recommended preimplantation genetic testing. Varicocele repair prior to SSR is recommended by 57.7%. Half of the respondents (57.4%) reported using ultrasound to identify the most vascularized areas in the testis for SSR. One-third proceed directly to microdissection testicular sperm extraction (mTESE) in every case of NOA while others use a staged approach. After a failed conventional TESE, 23.8% wait for 3 months, while 33.1% wait for 6 months before proceeding to mTESE. The cut-off of follicle-stimulating hormone for positive SSR was reported to be 12-19 IU/mL by 22.5% of participants and 20-40 IU/mL by 27.8%, while 31.8% reported no upper limit.
CONCLUSIONS: This is the largest survey to date on the real-world medical and surgical management of NOA by reproductive experts. It demonstrates a diverse practice pattern and highlights the need for evidence-based international consensus guidelines.
