उत्तर

Isthmus

Explanation:

Rete testis, vasa efferentia, and epididymis are all parts of the male reproductive duct system involved in sperm transport within the male reproductive system. The isthmus, however, refers to a part usually associated with the female reproductive tract (part of the fallopian tube) and is not part of the male reproductive system ducts.
