Study summary

Before commencing our study, we obtained approval from the local ethics committee. The study focused on patients who visited our urology outpatient clinic for infertility between January 2020 and March 2021. Eighty-four patients diagnosed with non-obstructive azoospermia were prospectively enrolled in the study.

Azoospermia was diagnosed after performing semen analysis at least twice, adhering to the criteria outlined by the WHO. All patients underwent karyotype analysis and Y microdeletion analysis. Testicular volumes were measured using Prader orchidometry and confirmed by scrotal ultrasonography.

For patients scheduled for Micro-TESE, elastography measurements were conducted in the supine position. These measurements were performed by the same radiologist in the Radiology department. A total of six points Shear Wave Elastography (SWE) measurements were recorded from each patient, including upper right, middle right, lower right, upper left, middle left, and lower left.

All patients underwent the micro-TESE procedure by the same surgeon. The procedure was first applied to the testis with a better volume and consistency. Samples of large and bright tubules were extracted using microforceps under a microscope, utilizing a magnification range of 20X-25X. The tissues obtained were subsequently assessed by the same embryologist who was present in the operating room. The embryologist provides biopsy results indicating the presence or absence of spermatozoa. If five or more mature spermatozoa are observed within the testicular tissues, the procedure is terminated. However, if fewer than five spermatozoa are identified in the tissues, the procedure is repeated on the contralateral testicle to ensure a comprehensive examination and thorough exploration. Tissues containing a satisfactory quantity of sperm were processed and preserved in the incubator until the Intracytoplasmic Sperm Injection (ICSI) procedure which was planned following the sperm cryopreservation of the patients whose sperms could be retrieved. In cases where sperm could not be retrieved from patients, testicular tissue was placed in Bouin's solution and sent for histopathological examination.

Before commencing our study, we obtained approval from the local ethics committee. The study focused on patients who visited our urology outpatient clinic for infertility between January 2020 and March 2021. Eighty-four patients diagnosed with non-obstructive azoospermia were prospectively enrolled in the study. Patients with obstructive azoospermia, hypogonadotropic hypogonadism, history of previous testicular disease, previous TESE, and history of chemotherapy or radiotherapy were excluded from the study.

Azoospermia was diagnosed after performing semen analysis at least twice, adhering to the criteria outlined by the WHO. All patients underwent karyotype analysis and Y microdeletion analysis. Testicular volumes were measured using Prader orchidometry and confirmed by scrotal ultrasonography.

For patients scheduled for Micro-TESE, elastography measurements were conducted in the supine position. These measurements were performed by the same radiologist in the Radiology department.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 29, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
