All of the options listed are male accessory reproductive structures. These include:

1. Bulbourethral glands: These glands produce a clear, slippery fluid that empties directly into the urethra. This fluid serves to lubricate the urethra and to neutralize any acidity that may be present due to residual drops of urine in the urethra.

2. Epididymis: This is a long, coiled tube that rests on the backside of each testicle. It transports and stores sperm cells that are produced in the testes.

3. Penis: This is the male organ used in sexual intercourse. It has three parts: the root, which attaches to the wall of the abdomen; the body, or shaft; and the glans, which is the cone-shaped end of the penis.

4. Prostate gland: This gland produces a fluid that contributes to semen, the male reproductive fluid. The prostate gland's secretions protect and nourish the sperm.

5. Seminal vesicles: These are sac-like pouches that attach to the vas deferens near the base of the bladder. The seminal vesicles produce a sugar-rich fluid (fructose) that provides sperm with a source of energy and helps with the sperms’ motility (ability to move). The fluid of the seminal vesicles makes up most of the volume of a man’s ejaculatory fluid, or ejaculate.
