IVF often comes to mind when we see male infertility, and when a patient with infertility encounters a problem he or she would like to do IVF, but natural conception is probably our highest pursuit. After all, IVF is a kind of artificial conception, which is more costly and damaging to women, and it is an artificial and unnatural fertility. In recent years, microsurgical techniques have found a new approach for the treatment of male infertility. 1. How are microsurgical techniques implemented? For microsurgery technique, the surgeon has to perform some surgical procedures on the patient with the help of an operating microscope, which is generally able to magnify 25-40 times, in an extremely fine operating environment. Microsurgical varicocele ligation, microsurgical vas deferens anastomosis by epididymis, and microscopic vas deferens anastomosis can be done. 2, obstructive azoospermia occurs for many reasons, of course, the international surgical recanalization rate from azoospermia to spermia can reach 70%-80%, the pregnancy rate can reach 30%-40%, the pregnancy rate is comparable to IVF, but its damage is far lower than IVF. 3, microscope technology and IVF technology, the success rate of microscope technology can reach about 80% or more, the conception factor and the number of intercourse of the patient has a relationship, and the object of treatment is only the male; do IVF to involve both men and women, especially women to artificial ovulation to pay a great price; cost to do microsurgery 10,000 to 15,000, IVF is known to generally in The operation time is more delicate and takes more time, but our treatment process is relatively simple, while IVF treatment process is complicated and the cycle is longer, and in terms of genetics, microscopic technology is natural conception, which is the highest law of fertility, while IVF is artificially and randomly selected, and the genetic risk is still great.
