1. Slight tear: it is not necessary to sew the penis after laceration. 2. Severe rupture: It is recommended to go to the reproductive plastic surgery department of the hospital to check whether there are problems such as excessive prepuce and abnormal prepuce frenulum, and sew the ruptured frenulum in time to treat the cause, so as to avoid repeated rupture of frenulum and induce other diseases. Causes of male penile frenulum rupture: Severe masturbation or rough sexual intercourse can lead to the rupture or complete disconnection of foreskin frenulum. The main reason for the rupture of prepuce frenum is the excessive wind load. For example, when masturbating, people want to ejaculate quickly because they are afraid of being seen, so the action is more intense to increase local stimulation. Second: in life, the development of penis is different, and the length and tension of prepuce frenulum are also different. If it is short and tight, it may break due to excessive force during sexual intercourse, causing bleeding and pain. In other words, male friends have penis fractures in their lives, mostly because male friends exert too much force or improper force during sexual intercourse. Penile frenulum rupture generally occurs in people with long foreskin. After the penile frenulum is broken, it should be sutured urgently or healed naturally.
