$The sexual response cycle in men includes four stages that occur in order: A description of what occurs during each stage: In the excitement stage, the penis becomes erect. This occurs in less than a minute in young men, during which time first the corpora cavernosa fill with blood, followed by the corpus spongiosum. The cremaster contracts, raising the testicles, and the nipples become erect. The excitement stage may last up to an hour. In the plateau stage, excitement and erection are maintained for up to several hours, or until the man is ready to undergo orgasm. The penis is fully erect, the testicles fully engorge and elevate, and the bulbourethral glands contract. This stage may be very short if the man wishes to reach orgasm quickly, or is unable to prevent immediate orgasm. Orgasm, or sexual climax, is a brief period of intense muscle contraction throughout the body, beginning in the genital area. Respiration and heart rate, and blood pressure, all peak during this time. In men, orgasm also involves emission (release of semen into the urethra) and ejaculation (forceful ejection of semen from the body). Resolution is the period of calm following the sexual release of orgasm. There is a loss of erection and the testicles descend to their normal position. In men, there is a refractory period, or rest period, before the next erection is possible.$ A description of what occurs during each stage:
