Efferent testicular tubules

The testicular tubules (ductuli efferentes) are specialized tubules of the testis that carry sperm from the testicle to the vas deferens. They are one of the components of the male reproductive system and play an important role in the reproduction process.

The testicular efferent tubules are about 40 mm long and are located in the testicular parenchyma. They start from the neck of the vas deferens and pass through the testicular parenchyma to its capsule. Inside the testicular tubules there are sperm, which move along them to the vas deferens.

The seminiferous tubules are ducts that carry sperm from the testicle to the urethra. They are about 30 cm long and consist of two parts: intrauterine and extrauterine. The intrauterine part is located inside the testicle, and the extrauterine part is located outside it.

When functioning normally, the efferent and seminiferous tubules work together to transport sperm from the testicles to the prostate and bladder. However, if there is any abnormality in the functioning of these tubules, it can lead to infertility or other health problems in men.

Efferent testicular tubules (ductuli eferentes testiculi; synonyms: efferent duct, ductal atresia) are branched ducts through which mature sperm move to the female genital tract and carry oxygen in the testicular tissues. Testicular tubules are also called permanent sections of its neurovascular bundles that make up its structure from the opposite end.
