Description
Getting snipped or having a vasectomy is a surgery that will sterilize a man, Once this surgery is completed the sperm can no longer move from the testes to the penis and thus there is no possibility of pregnancy. This has a very high success rate and usually has no complications (out side of being sore and not wanting to sit down for a week), but after it heals it usually will not affect your sexual performance or libido.
Effectiveness
A vasectomy is 100% effective once it is confirmed successful, but you will need a doctor to test your ejaculate or cum to make sure it does not contain sperm.
Procedure
Talk to your doctor for full details as methods do change with time, but usually a small cut or incision will be made in the scrotum and a section of the vas deferens is removed. After this your sperm will no longer be able to move from the testes to the penis making you 100% sterile. It takes about 15 minutes to complete at a doctor’s office, and you will be given local anesthetic. For more information please talk your doctor and ask for a referral to a specialist.
Drawbacks
A vasectomies will not protect you from STDs, and due to the nature of the surgery should be considered permanent.
