Prostate specific antigen (PSA) level test can determine the speediness of normal cancer signaling for generation of semen by the prostate, signaling for generation of mucous in the prostate, and signaling for generation of mucous by Leydig cells.
10) Based on what we know, the surgical removal of the seminal vesicles would likely cause sterility because PSA would not be produced. B) It would increase sterility because sperm would not be able to exit the body. C) It would likely reduce the volume of semen. D) It would enhance the fertilization potency of sperm in the uterus.
