With the implementation of the two-child policy, many couples have successfully embraced the second child, but there is also a part of the response to the previous national policy, do the ligation surgery, can not hold the second child, then how to do? Listen to me in detail: vasectomy is a kind of vasectomy, after the ligation of the formation of the medical origin of the vas deferens obstruction, sperm can not be discharged through the normal ejaculation, so as to achieve the purpose of sterilization. To reproduce again, surgical vasectomy is an effective method. The disadvantage is that it needs to be operated under a microscope, which makes it difficult to operate, and the operator needs to be professionally trained in order to achieve a high success rate. It is also time-consuming and requires more than half a year of postoperative recovery before it is clear whether the vasectomy has been successful or not. For patients with good testicular development and normal spermatogenesis, direct testicular or epididymal puncture for sperm extraction, followed by IVF treatment is also a good choice. The disadvantage is that IVF is more expensive and requires the female partner to cooperate with egg retrieval and transplantation. For patients with testicular dysplasia and poor spermatogenesis, artificial insemination with sperm from a sperm bank is the best option. The disadvantage is that the sperm is someone else’s and is not related to the male partner. Special attention should be paid to the condition of the patient’s spouse as well as to the fertility treatment plan for patients after sterilization. If the partner is older or has a combination of disorders that affect fertility, it is advisable to consider the treatment strategy in conjunction with a reproductive gynecologist, rather than missing out on the opportunity to have a child with assisted reproduction technology by considering only the male partner’s factors.
