B) they stay the same for many generations
A/an <u>seminal vesicle</u> is a fluid-filled sac in the scrotum along the spermatic cord leading from the testicles.
- The male reproductive system includes a pair of glands called seminal vesicles that are located on the back of the bladder base in men.
- Their major job is to create the semen-making fluid that is expelled during ejaculation.
- The majority of the fluid that makes up semen is produced and stored by two tiny glands called seminal vesicles.
- The seminal vesicles' fluid is sent into the ejaculatory duct during ejaculation, where it might mingle with sperm and other reproductive fluids.
- The androgen-dependent seminal vesicle glands release a sizeable portion of the fluid that eventually turns into semen (seminal fluid).
- The majority of species' contributions to semen volume come from seminal vesicle glands.
