Azoospermia usually has no self-conscious manifestations, and mostly seeks medical treatment for infertility. Azoospermia refers to the absence of sperms in the patient’s semen, i.e., no sperms are found inside the semen until there is no pregnancy or when the semen is examined before conception. Therefore, patients with azoospermia usually have no self-conscious symptoms, and mostly seek medical treatment due to infertility. Azoospermia is categorized into obstructive azoospermia and non-obstructive azoospermia. Crohn’s syndrome is caused by chromosomal abnormalities, also known as congenital varicocele hypoplasia, and most of the patients also have no sperm, and clinically there will be other features, such as a taller, stouter body. However, due to the low sex hormones in the body, the physiological age is significantly younger than the patient’s actual age. Once the patient is diagnosed with azoospermia, it is recommended to go to the hospital as soon as possible for examination and treatment under the guidance of the doctor after clarifying the cause of the disease.
