输精管切除术的动机。

Lancet. 1978 Mar 11;1(8063):546-8. doi: 10.1016/s0140-6736(78)90565-2.

Men under 35 tend to request vasectomy for different reasons from those given by older men. Potential sexual, marital, or ageing problems seemed to motivate older couples, and problems related to family size, recent pregnancy, and difficulty with contraception the younger ones.

35岁以下的男性要求进行输精管切除术的原因与年长男性不同。潜在的性、婚姻或衰老问题似乎促使年长夫妇这么做，而与家庭规模、近期怀孕以及避孕困难相关的问题则促使年轻夫妇要求进行输精管切除术。
