Men serve as the primary pillar of a family, and health issues in males can be particularly alarming. Therefore, it's crucial to remain vigilant about diseases affecting men. For instance, early diagnosis is essential upon developing azoospermia. So, how is male azoospermia diagnosed? Let's explore this together.
Experts indicate that the three most common causes of azoospermia are: congenital bilateral absence of the vas deferens, testicular atrophy following consumption of raw cottonseed oil, and Klinefelter syndrome. These conditions are causes of azoospermia but must be distinguished from it to avoid misdiagnosis, missed diagnosis, and delayed treatment.
Generally, confirming azoospermia requires the following differential diagnoses:
1. Clinically, detailed differentiation between these three conditions and azoospermia can be achieved through physical examination, semen analysis, endocrine hormone testing, sex chromosome analysis, and testicular pathology.
II. It is important to note that for patients with azoospermia due to testicular atrophy, a detailed history should be obtained regarding whether they originate from cotton-producing regions and whether they have consumed homemade crude cottonseed oil, along with the duration of consumption. Infertility caused by crude cottonseed oil consumption is a unique etiology among infertility patients in China.
Additionally, azoospermia must be distinguished from oligospermia and necrospermia.
I. Oligospermia: Oligospermia refers to male infertility where the sperm count in semen is below normal levels but fertility potential remains intact. The World Health Organization defines oligospermia as a sperm count below 20 million per milliliter.
II. Necrospermia: This condition involves reduced sperm viability, diagnosed when over 40% of sperm in semen analysis are dead. However, artificially elevated dead sperm counts due to improper collection methods or non-standard specimen handling constitute pseudonecrospermia, requiring careful differentiation.
The above outlines diagnostic approaches for male azoospermia. It is crucial for everyone to understand these methods. Naturally, when men experience physical issues, selecting appropriate diagnostic methods is paramount. Only after thoroughly understanding the condition can scientific medication and treatment be administered based on the specific diagnosis, ensuring prompt resolution of the problem.
