Acupuncture and the Genitourinary System: Anti-Inflammatory Effects and Clinical Potential

The urinary and reproductive systems originate from the same embryological tissues. Because of this shared developmental origin, they are closely interconnected in both structure and function, and diseases of one system frequently affect the other.

Recent clinical studies show that acupuncture has therapeutic benefits for a wide range of urinary tract inflammatory conditions, including:

• Upper urinary tract inflammation (e.g., pyelonephritis, ureter inflammation)
• Lower urinary tract inflammation (e.g., cystitis, urethritis)
• Urinary irritation symptoms — frequency, urgency, dysuria, hematuria
• Systemic inflammatory symptoms — fever, chills, fatigue

Acupuncture also shows positive effects in treating reproductive system inflammation, including vaginitis, cervicitis, endometritis, pelvic inflammatory disease, salpingitis, peritonitis, and inflammation of pelvic connective tissues.

1. Electroacupuncture for Ovarian Hyperstimulation Syndrome (OHSS)

According to the cited research (Table S1), electroacupuncture (EA) pretreatment at SP6 and CV4 significantly reduces multiple inflammatory and hormonal markers in OHSS models:

• Lower IL-6, TNF-α, MCP-1, and VEGF
• Reduce serum progesterone and testosterone
• Decrease ovarian weight and vascular permeability
• Prevent further disease progression

Proteomic analysis further suggests that EA may exert anti-inflammatory effects through up-regulation of CD200, a member of the immunoglobulin superfamily that suppresses pro-inflammatory cytokine release within the ovary.

2. Acupuncture at HT7 and Maternal-Separation–Induced Depression

Stimulation of HT7 (Shenmen) has been shown to:

• Relieve depressive-like behavior (reduced immobility time)
• Lower plasma corticosterone
• Reduce IL-1β and IL-6
• Decrease glial cell-derived neurotrophic factor

These findings indicate that acupuncture may help modulate stress-induced changes in the central nervous system and hormone regulation. However, the exact cell types involved and the detailed molecular mechanisms remain unclear and require further study.

3. Research Gaps: Urinary Tract Inflammation

Although acupuncture has demonstrated therapeutic potential for urinary tract inflammatory diseases, current mechanistic research is still limited. More studies are needed to clarify the pathways involved in immune regulation, cytokine signaling, and genitourinary tissue repair.

泌尿系統與生殖系統在胚胎發育時來自共同來源，因此在結構與功能上密切相關， 兩者的疾病常彼此互相影響。

近年臨床研究發現，針灸對許多泌尿道發炎性疾病具有良好療效，包括：

• 上泌尿道發炎：腎盂腎炎、輸尿管炎
• 下泌尿道發炎：膀胱炎、尿道炎
• 泌尿刺激症狀：尿頻、尿急、排尿疼痛、血尿
• 全身性發炎症狀：寒顫、發燒、疲倦

針灸對生殖系統發炎亦具有良好療效，如陰道炎、子宮頸炎、骨盆腔發炎、 子宮內膜炎、輸卵管炎、腹膜炎與骨盆結締組織發炎等。

一、電針在卵巢過度刺激症候群（OHSS）中的應用

文獻（Table S1）指出，施以電針 SP6、CV4 可明顯降低 OHSS 大鼠的多項發炎與荷爾蒙指標：

• 降低 IL-6、TNF-α、MCP-1、VEGF
• 降低血中黃體素、睪固酮
• 減少卵巢重量與血管通透性
• 延緩或阻止病情惡化

蛋白質體學研究顯示，電針的抗發炎作用可能透過上調 CD200（免疫球蛋白超家族成員）來實現， 其可抑制卵巢中促發炎細胞激素的釋放，進而影響 OHSS 的病程。

二、刺激 HT7（神門）改善母嬰分離造成的憂鬱行為

刺激HT7（神門）於母嬰分離模型中可：

• 減少類憂鬱行為（減少不動時間）
• 降低血漿皮質酮濃度
• 降低 IL-1β、IL-6
• 降低神經膠質細胞來源的神經營養因子

這顯示針灸可能調節壓力相關的中樞神經與內分泌變化， 但確切牽涉的細胞類型與分子機制仍需更多研究釐清。

三、泌尿道發炎研究仍有限，需更多探討

儘管針灸在泌尿道發炎的臨床治療中展現潛力，但現有的基礎研究仍相當有限。 未來需要更多研究探討其免疫調節途徑、細胞激素訊號與泌尿生殖組織修復機制。
