Solution

Yes, that's correct. Ejaculation is controlled by the sympathetic division of the autonomic nervous system. This process involves two steps: emission and expulsion.

  1. Emission: This is the first stage of ejaculation, which involves the deposition of seminal fluid into the posterior urethra. This process is facilitated by the contraction of the prostate gland, seminal vesicles, and vas deferens.

  2. Expulsion: This is the second stage of ejaculation, which involves the release of the seminal fluid out of the body. This process is facilitated by the contraction of muscles at the base of the penis.

It's important to note that while the autonomic nervous system plays a key role in ejaculation, other factors such as hormones and psychological state can also influence this process.
