Occult azoospermia is a condition in which a man has a basic semen test and finds that spermatozoa are not visible on routine examination and a very small number of spermatozoa are observed under a microscope. Cryptogenic azoospermia can be caused by conditions such as hypogonadotropic hypogonadism, blockage of the vas deferens, and intratesticular obstruction. The causes are different and the treatments are different. The treatments include medication, surgery and assisted reproductive technology. 1. Drug treatment: it is suitable for patients with azoospermia caused by hypogonadotropic hypogonadotropic hypogonadism, and is usually treated with a combination of chorionic gonadotropin and postmenopausal urogenital gonadotropin, which should be applied under the guidance of a doctor. 2. Surgical treatment: In cryptogenic azoospermia caused by obstructive diseases of the vas deferens, surgical intervention is used to repair and recirculate the blocked ducts. 3. Assisted Reproductive Technology (ART): Patients with intratesticular obstruction who are unable to undergo surgery or who have poor surgical results can try intracytoplasmic sperm injection (ICPI), which is a non-coital method of delivering sperm into the female reproductive tract, so as to fertilize the egg and sperm for the purpose of achieving pregnancy. If you have hidden azoospermia, it is recommended that you go to a regular hospital in a timely manner to clarify the cause of the disease under the guidance of a physician to give appropriate treatment options to avoid serious consequences.
