The “comprehensive two-child” policy has been implemented, and in recent months, there has been a large increase in the number of couples visiting maternity and child hospitals for fertility evaluations. According to statistics, 15 to 20 percent of infertile men are due to azoospermia. And three to four percent of azoospermia patients have non-obstructive azoospermia – traditionally referred to as the “terminal disease of infertility”. Can azoospermia patients have children of their own? The answer is: yes. A new technique called “testicular microsperm extraction” can “search” for sperm tissue from the testicles, grow sperm, and inject eggs through single sperm, thus realizing the dream of having their own offspring. Azoospermia is a condition in which no sperm can be detected in the semen of the patient. Azoospermia accounts for about 15 to 20 percent of male infertility patients. “In our Reproductive Medicine Center clinic, three to four new patients with azoospermia are seen every day. This can be very painful for a man and family who desire a child.” What is azoospermia? A semen test reveals no sperm, and we call it azoospermia. As one of the most difficult infertility conditions to treat, azoospermia had caused deep suffering to patients and numerous problems to doctors.” Failure to find a single sperm in the ejaculated semen for three consecutive times is called azoospermia.” Why does azoospermia occur? 1. Azoospermia: The testicles are the only place where sperm are produced, and without them, there is no sperm to speak of. Since there are no testicles, there is no therapeutic value. 2.Small testicles: The testicle size of adult men is usually 12-20 ml, if it is less than 6 ml, we call it small testicles. Most of such testes have very low spermatogenic ability, and some are only focal spermatogenic, but they cannot be discharged. It may be caused by chromosomal abnormalities or abnormal hormone levels. 3. Genital injuries or infections: External injuries leading to testicular injury or torsion, spermatic cord torsion, etc., or trauma from hernia repair surgery, prostate surgery, etc., and mumps in early childhood can also affect testicular function and lead to sperm production disorders. This condition is mainly a matter of prevention and timely and effective measures. 4, varicocele: this condition will seriously affect the blood supply to the testes, which in turn will affect the sperm production function of the testes, and will also occur a large reduction in sperm or even will disappear. Timely surgery or medication (for mild cases) can restore the reproductive function of most patients. 5. Bilateral cryptorchidism: In this case, the testicles do not reach the scrotum where they should be, and stay in the abdominal cavity because the temperature is much higher than that of the scrotum, so there is no way for sperm to be produced, and azoospermia can also occur. This situation can be treated surgically, and it should be noted that the earlier the treatment, the better the results. 6, male consumption will make the sperm reduction food: such as cottonseed oil the oil contains a component called cotton phenol, this component can inhibit sperm production, so people used to male contraception, but if the men who intend to have children eat more, it will happen sperm reduction, or even disappear. If you eat too much cottonseed oil, stop after it is difficult to return to normal. 7, engaged in radioactive, chemical materials work: sperm is very fragile, if in front of powerful electromagnetic waves, radiation, paint, stupid and other chemical materials, will be extinguished. The cause of the disease can only be prevented.
