How to judge non-obstructive azoospermia or obstructive azoospermia

The diagnosis of non-obstructive azoospermia and obstructive azoospermia is mainly based on semen analysis and examination of the vas deferens, including the presence or absence of sperm, patency of the vas deferens, etc., and sometimes other examinations are required. The diagnosis of non-obstructive azoospermia and obstructive azoospermia is mainly based on semen analysis and examination of the vas deferens. The following are some specific methods: Semen analysis: If there are no sperm in the semen, further microscopic examination after centrifugation is required. If there are still no sperm, it may be non-obstructive azoospermia. If there are sperm in the semen, then obstructive azoospermia is less likely, but a vas deferens examination is still required to confirm the diagnosis. A vasogram, seminal vesiculography, or urethrography may be used to determine whether the vas deferens are patent. Obstructive azoospermia may be present if the vas deferens are blocked or absent. Other tests: Hormone levels, testicular biopsies, etc. may also be required to rule out other possible causes of azoospermia. It should be noted that for some special groups, such as varicocele patients, even if sperm exists in semen, it cannot completely rule out the possibility of vas deferens obstruction. In addition, some congenital diseases or acquired injuries may also lead to azoospermia, which requires comprehensive consideration of various factors for judgment. In conclusion, the diagnosis of non-obstructive azoospermia and obstructive azoospermia requires a comprehensive analysis of semen analysis, vas deferens examination and other relevant examination results, and combined with specific conditions. For azoospermia patients, timely medical treatment, comprehensive examination and diagnosis should be carried out in order to formulate appropriate treatment programs.
