Where are the seminal vesicles located and what is their primary function?

The seminal vesicles are indeed located posterior to the urinary bladder. Their primary function is to produce a significant portion of the fluid that makes up semen. This fluid contains various components including fructose, which provides energy for sperm, as well as other substances that help to nourish and transport sperm during ejaculation.

Understanding the anatomy is crucial, as the seminal vesicles play a key role in male reproductive physiology. The positioning of these glands is important for their functional interaction with the prostate and other male reproductive organs. By being situated posterior to the urinary bladder, they are strategically placed to release their secretions into the ejaculatory duct, which then joins with the urethra during the process of ejaculation.
