Azoospermia is a relatively common clinical condition, and patients with azoospermia can often be encountered in male infertility. Azoospermia is divided into two cases, as follows: 1. Non-obstructive azoospermia: the testes do not have the function of producing sperm, and it is not a blockage of the vas deferens, in which case sperm can be obtained in about 50% of cases through microscopic sperm extraction, and then go for IVF to conceive; 2. Obstructive azoospermia: such as epididymal obstruction, vas deferens obstruction, as well as prostate and seminal vesicle gland abnormalities, i.e., problems with the above-mentioned ducts The azoospermia can be called obstructive azoospermia. In obstructive azoospermia, if the ducts are unblocked, conception can occur. Alternatively, even if the ducts cannot be unblocked, IVF can be performed by obtaining sperm through epididymal puncture to help conception.
