Patient's question:
Why is there a sound during or after intercourse, like air being released? What causes it, and are there ways to avoid it?Doctor's answer:
Hello: The condition you mentioned may be a symptom of "yin chui" (vaginal gas emission). Occasionally, some women visit gynecological clinics and hesitantly describe the sensation of air flowing out of their vagina, sometimes accompanied by a sound similar to flatulence from the anus, causing them great alarm. This is what traditional Chinese medicine refers to as "yin chui," where "if a woman's vagina frequently emits air or makes a sound like flatus, it is called yin chui." Many patients feel ashamed and dare not tell their husbands or doctors, so the number of those seeking medical attention is much smaller than the actual number of patients, making it seem uncommon in clinical practice.So, what exactly is yin chui, and what should be done if it occurs? Here is a brief introduction to its origins and mechanisms.
1. Postpartum weakness and yin chui
Most cases of yin chui occur in postpartum women, especially in multiparous women with weak constitutions. From a traditional Chinese medicine perspective, this is attributed to "great deficiency of qi and blood, and sinking of the middle qi." To understand its mechanism, we must look at the changes in the birth canal during childbirth. In women who have never given birth, the vagina is shaped like a trumpet, wider inside and narrower outside. Under normal conditions, the pelvic floor muscles and fascia surrounding the vagina maintain a certain tension, providing support to the vaginal walls, keeping the front and back walls pressed together, eliminating the lumen, and allowing the labia majora to close on both sides of the external genitalia, covering the vaginal opening like two closed doors, preventing air from entering the vagina. During childbirth, as the fetus passes through the birth canal, the vagina significantly expands and loosens. The pelvic floor muscles and fascia that support the vaginal walls tear or stretch excessively, losing their elasticity. As a result, the front and back walls of the vagina cannot adhere closely, forming a cavity. Perineal lacerations cause the vaginal opening to widen, unable to cover the
