Abstract:
New child wish after vasectomy: vasovasostomy or assisted reproductive medicine? In the case of a new child wish after vasectomy, there are two options: vaso-vasostomy (VV) or biopsy of the testicle associated with intra-cytoplasmatic sperm injection (ICSI). Both methods are not reimbursed. The VV offers a cumulative pregnancy rate of 28-40%, depending on pre-, intra- and postoperative factors. The age of the female partner and the time after vasectomy are the most important factors. Pregnancy rates after ICSI are 29-41% per transfer. Cumulative pregnancy rates vary between 60-80%. Malformation rates after ICSI in this special collective are not investigated yet, the "general" ICSI-collective differs completely compared to the a priori fertile couples after vasectomy. Couples have to inform themselves about the experience of the doctors and their rate of success in order to minimize the risk of failure.
