Keep using birth control until you have done successful semen testing. See HERE for more information on semen testing. It is recommended that two months after your vasectomy, you do a home semen analysis using “SpermCheck Vasectomy”. If you have two “low count” results, you can stop using other forms of birth control. If it is “high count”, repeat the SpermCheck one month later. If it is still “high count”, then please contact Dr. Tonozzi to make a plan.
