Testosterone is responsible for the development of male characteristics, including muscle mass and strength, fat distribution, bone mass, facial hair growth, voice change, and sex drive. Low sperm count can be caused by a number of issues and create difficulty getting pregnant. Which structure carries sperm from the testes to the ejaculatory duct? For about five weeks, the sperm travel through the epididymis, completing their development. The prostate gland contributes additional fluid to the ejaculate. Internal organs include the vas deferens, prostate and urethra. After sperm is created in the seminiferous tubules, sperm cells travel toward the epididymis through the rete testis.

Orchiopexy is usually performed: The efferent ducts are a series of tubes that join the rete testis to the epididymis. The primary germ cells that enter the process of spermatogenesis are diploid and initially divide via mitosis to produce spermatogonia, which are also diploid. Only an examination by a healthcare provider can determine whether the growth is benign (non-cancerous) or malignant (cancerous). c.

The epididymis is a duct-like organ that connects the testis to the vas deferens and is comprised of four anatomical regions: the initial segment, caput, corpus, and cauda.
