Testicleless
Introduction
Introduction The testes are male internal reproductive organs. Normal men have two testes, which are located on the left and right sides of the scrotum. Under normal circumstances, the testicles fall into the scrotum in the late stage of development of the fetus. However, common testicular diseases can lead to testicular insufficiency, testicular ectopic and testicular deficiencies, and no testicular symptoms, such as cryptorchidism, congenital testicular disease, dwarfism and so on. Testicular decline is a very complex process of embryonic development, which is influenced by endocrine, genetic, and physical and mechanical factors. These abnormalities can cause cryptorchidism.
Cause
Cause
First, the majority of patients with unknown causes, no family history, only a small part of the family history, is autosomal recessive inheritance.
Second, secondary is relatively rare, any lesion damage to the anterior pituitary or hypothalamus can cause growth and development stagnation, common tumors (such as craniopharyngioma, chiasm or hypothalamic glioma, pituitary xanthoma, etc.) Infection (such as encephalitis, tuberculosis, schistosomiasis, toxoplasmosis, etc.), trauma, vascular necrosis and X-ray injury.

Male examination of semen volume
The fetal testis is destroyed by a certain toxin. In the inguinal canal and high intra-abdominal or testicular absent, clinical tests often do not touch the testes. Also pay attention to cryptorchidism, timely ultrasound monitoring of the abdomen. And other related checks, such as MRI, sex hormones and other tests.
Diagnosis
Differential diagnosis
Patients with cryptorchidism often come to the doctor because of scrotal emptiness and no testicles inside. There are also patients who are treated with "" as the main complaint, or because of bilateral cryptorchidism and infertility after marriage. Diagnosis is generally not difficult. However, the identification of cryptorchidism and testis without the testicle should be taken seriously, because the latter does not require surgery.
For unilateral testicular defects, it is difficult to confirm the diagnosis before surgery, and the hormone test is normal. Gonadal venography, laparoscopy, B-ultrasound, and CT scan may be helpful in the diagnosis, and surgical exploration is still needed when necessary.
