Surgical vaginal tightening refers to the removal of the lax mucosa of the vagina and double suturing of the vaginal wall to contract the vaginal sphincter and the levator muscle and increase the vaginal tone to tighten the vaginal opening, thus improving the problem of vaginal laxity that affects sex life after childbirth. However, surgical vaginal tightening often involves certain risks, as follows: 1. Reduced sexual pleasure: surgical vaginal tightening can cause scarring of the vagina and change the elasticity and wetness of the vagina, resulting in uneven vaginal clamping force, which may make it difficult to reach orgasm and lead to sexual indifference over time, and may affect the quality of life of couples. 2. The vagina itself contains a large number of bacteria, most of which are pathogenic, and surgical vaginal tightening can create good conditions for these bacteria to proliferate, which may lead to post-operative infection. After vaginal tightening, some women may develop bladder bulge, leading to tension incontinence, mainly because of the operation damage to the urinary system.
