Avoid intercourse within 11 days after finger reimplantation, and if you want to have intercourse, it will be less restrictive after about 3 weeks. Because the first 11 days of finger reimplantation is a period of vasospasm, after the finger is stimulated, it is easy to cause arterial spasm and thrombosis, which will lead to the failure of reimplantation. Within 11 days of finger reimplantation, anti-inflammatory, anti-coagulation and anti-spasmodic are needed. Firstly, anti-inflammatory antibiotics should be applied to prevent local infection. In addition, anticoagulation and anti-spasmodic measures should be taken to prevent thrombosis of blood vessels, which may lead to blood flow obstruction in the reimplanted stump of the severed finger, thus affecting the local blood flow and causing the reimplantation to fail. Then about 3 weeks after the life is not too restrictive, within 3 weeks is to try to avoid coitus, to prevent excessive excitement lead to vasospasm and reimplantation failure.
