Question
Maturing sperm gain their ability to swim while in the ________.
- epididymis
- seminiferous tubules
- ductus deferens
- urethra
- ejaculatory duct
Solution
The correct answer is epididymis.
Sperm maturation occurs in the epididymis, which is a coiled tube located behind the testis. During their passage through the epididymis, sperm undergo significant maturation processes, including the acquisition of motility, which is essential for their ability to swim. The seminiferous tubules are where sperm are initially produced, but they do not gain the ability to swim until they reach the epididymis. The ductus deferens, urethra, and ejaculatory duct are involved in the transport of sperm but do not play a role in their maturation.
