Case sharing: Patient Chen, 25 years old, has been living with his girlfriend for 2 years and has never used contraception, however, they are distressed that they have not been able to conceive their own baby. After unsuccessful treatment in several local hospitals, he was referred to our male department and was considered to have obstructive azoospermia after systematic examination. Although the treatment of this disease is very difficult, our male department was the first to carry out male microsurgery in the province as early as 2014 and has accumulated rich experience in the treatment of obstructive azoospermia. After a comprehensive assessment of the condition and careful communication and guidance by the medical team of the male department, the patient and his family decided to perform microscopic bilateral vas deferens epididymal anastomosis and testicular sperm extraction and freezing. Traditionally, azoospermia is divided into two categories: obstructive and non-obstructive. The so-called “reproductive insurance”, that is, in order to prevent male fertility decline or damage, the use of ultra-low temperature freezing method, ultra-low temperature preservation of sperm in liquid nitrogen in advance, when the need for artificial recovery, for assisted reproductive technology to help conceive their own offspring. In the future, patients with azoospermia who come to our male department can undergo testicular sperm retrieval at the same time as microsurgical treatment, and the testicular tissue taken during the operation will be sent to the human sperm bank of the Specialist Hospital for Reproduction and Genetics for freezing and storage for later assisted reproduction, avoiding the possibility of secondary surgery. This technological breakthrough provides a double insurance for azoospermia patients, making it no longer a dream for azoospermia patients to have a baby of their own.
