Patient's question:
Why is there a sound during sexual intercourse after vaginal intercourse, which feels like air being released? What causes it, and is there a way to avoid it?Doctor's answer:
Hello: The situation you mentioned may be a symptom of "yin chui" (vaginal gas emission). Occasionally, some women visit gynecological clinics and hesitantly confess that they experience 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 far fewer than the actual number of patients, making it appear 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 multiparous women with weak constitutions, which is considered "extreme deficiency of qi and blood, and sinking of the middle Qi" in traditional Chinese medicine. 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, with a wider interior and narrower exterior. Under normal circumstances, 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 causing 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. The perineal laceration causes the vaginal opening to widen, unable to cover the...
