After a vasectomy, it is typically recommended to wear a jock strap or supportive underwear immediately following the procedure for at least the amount of time suggested by your healthcare provider. This is to minimize tension on the spermatic cords, which are responsible for transporting sperm and wrapping around the testicles to hold them in place.
It is also important to keep the area around your vulva – where the inner thighs meet the pubic bone region – clean and dry to avoid infection. The skin of the vulva can become red and sensitive immediately after the vasectomy, and it may be slightly painful to touch.
By wearing jock straps or underwear, you help keep this area as comfortable as possible during the healing process. However, it's also important to avoid tight underwear that could cut off circulation, which could lead to issues such as orchitis, which is inflammation of the testicles.
Overall, wearing supportive underwear after a vasectomy is generally recommended for a few days to a few weeks, but it's crucial to heed the specific guidance of your healthcare provider for the best recovery experience.
