Is it possible to get pregnant 2 months after vasectomy?

Possible...: The safety & effectiveness after vasectomy can be claimed only after post-vas semen exam shows no sperm. Largely, some 85% of post-vas men will be sperm-free after 15 ejaculations or in months; despite claimed sperm-free, post-vas recanalization does still occur. Despite stressing these important post-vas F/U, still less than 45% of patients would follow post-vas instruction to get post-vas semen.
