How to treat male vas deferens blockage?

Patient's question:

Vas deferens blockage

Doctor's answer:

Epididymal obstruction is not an independent disease but rather a symptom caused by various conditions. Treatment should first address the underlying disease, such as anti-inflammatory, anti-tuberculous, or anti-tumor therapies. In some cases, the obstructed area can be excised and the ends reanastomosed, or sperm may be directly aspirated from the epididymis for artificial insemination.
Traditional Chinese Medicine (TCM) that epididymal obstruction is caused by blood stasis blocking the semen duct. This impairs the downward flow of kidney essence, preventing ejaculation and fertility, and is classified into two types: cold stasis and damp-heat stasis. Treatment focuses on promoting blood circulation, resolving stasis, and generating new blood to restore the blocked duct.
1. Damp-heat stasis type: Fatigue, soreness in the lower back and knees, a heavy pain in the testicles and perineum, frequent urination with yellowish and cloudy urine, yellow greasy tongue, and slippery wiry pulse. Treatment should clear heat and resolve dampness, the semen duct.
2. Cold stasis type: Cool pain in the perineum and testicles, worsening in cold conditions, cloudy urine, pale tongue with white coating, and deep wiry pulse. Treatment should promote blood circulation, resolve stasis, and warm the meridians.
