Dear would - be parents, on the long journey of seeking to have a child, many families are filled with great anticipation, yet they may also encounter various setbacks. Today, I'd like to talk to you about a disease that can cause male infertility - obstructive azoospermia.

Obstructive azoospermia, simply put, means that the sperm transport channels are blocked, resulting in no sperm in the ejaculated semen. Under normal circumstances, sperm are produced in the testicles, and then pass through a series of ducts such as the epididymis and vas deferens, and finally are ejaculated out of the body along with the semen. However, if there is an obstruction in any part of these ducts, sperm cannot be discharged smoothly, thus leading to infertility.

There are various causes of obstructive azoospermia. Epididymitis is one of the common causes. The epididymis is an important place for sperm maturation and storage. Once the epididymis becomes inflamed, it may cause the lumen to narrow or become blocked. Vasectomy can also lead to obstruction. Although it is a common male sterilization method, if there is a need for fertility later, this problem may be faced. In addition, congenital bilateral absence of the vas deferens is a congenital disease. Patients are born without vas deferens, so naturally, they cannot ejaculate sperm.

This disease itself does not bring obvious discomfort symptoms. Therefore, many patients often discover it only when they fail to conceive after trying to get pregnant and undergo a semen examination. After finding that there is no sperm in the ejaculated semen, doctors will further use methods such as physical examination, reproductive hormone determination, ultrasound examination, and seminal plasma biochemical examination to determine whether it is obstructive azoospermia and the specific location of the obstruction.

Let me share a case with you. Mr. Zhang and his wife had been trying to conceive for two years without success. After going to the hospital for an examination, it was found that Mr. Zhang had obstructive azoospermia, and the cause was previous epididymitis. This made them very frustrated, but fortunately, they did not give up.

For patients with obstructive azoospermia, in - vitro fertilization (IVF) technology is an important hope for fertility. Through surgical sperm retrieval, such as epididymal puncture sperm retrieval or testicular sperm extraction, after obtaining sperm, with the help of IVF technology, sperm and eggs are combined in vitro to form an embryo, which is finally transplanted into the woman's uterus.

In addition, the COSTAIVF sperm bank and egg bank can provide strong support for families in need. The sperm bank strictly screens sperm donors to ensure the quality and motility of sperm, providing a reliable option for families that cannot obtain usable sperm. The egg bank can preserve healthy eggs, providing a guarantee for the preservation of female fertility. As an expert in the field of reproductive medicine, Dr. Nathan Zhang has rich clinical experience and professional knowledge. He will formulate personalized treatment plans according to the specific conditions of patients, from the selection of sperm retrieval plans, to the control of various details in the IVF process, and then to the nursing guidance after transplantation. Dr. Nathan Zhang will provide professional advice and assistance to help every family increase the probability of success on the journey of seeking a child.
