obstructive azoospermia

The most direct manifestation of obstructive azoospermia is the absence of sperm in semen routine examination. Its main reason is due to obstruction of the vas deferens, or stenosis of the epididymis vas deferens junction, inflammation of the epididymis, etc. Clinically, it may show local pain and swelling of the scrotum. Palpation can find induration, bead-like changes, etc. Obstructive azoospermia can be diagnosed by laboratory tests and color Doppler ultrasound or sperm tract imaging. Surgery is usually required, such as vasectomy, vasectomy and reconstruction of epididymal vasectomy. Obstructive azoospermia is better than congenital azoospermia.
