When describing the male sexual response to a group of students, the instructor determines that the teaching was successful when they identify emission as which of the following?
A) Semen forced through the urethra to the outside
B) Movement of sperm from the testes and fluid into the urethra
C) Dilation of the penile arteries with increased blood flow to the tissues.
D) Body's return to the physiologic nonstimulated state
B
Feedback:
Emission refers to the movement of sperm from the testes and fluids from the accessory glands into the urethra, where it is mixed to form semen. As the urethra fills with semen, the base of the erect penis contracts, thus increasing pressure. This pressure forces the semen through the urethra to the outside (ejaculation). Dilation of the penile arteries with increased blood flow describes erection. The body's return to the physiologic nonstimulated state describes resolution.
