Between 1972 and 1977 vasovasostomy to reverse a previous vasectomy for contraception has been attempted in 27 cases. The procedure was abandoned as a technical impossiblity in only 1 case. The first 17 have been studied and in these there have been 11 pregnancies, 10 of which have already come to term with the birth of normal children, including one set of twins. Of the remainder, 2 are known to have oligozoospermia and 4 have been lost to follow-up although 2 of these were euspermic when last heard of. In spite of the encouraging results it is considered that there are no grounds for altering the present basis of vasectomy counselling in which the operation is described as likely to be irreversible.
1972年至1977年间，对27例先前因避孕而接受输精管切除术的患者尝试进行了输精管吻合术以恢复生育能力。仅1例因技术上无法完成而放弃该手术。对前17例患者进行了研究，其中有11例怀孕，10例已足月并产下正常婴儿，包括一对双胞胎。其余患者中，已知2例患有少精子症，4例失访，不过其中2例最后一次检查时精子正常。尽管结果令人鼓舞，但仍认为没有理由改变目前输精管切除术咨询的基础，即该手术被描述为可能不可逆转。
