Questions: Masters and Johnson noted in describing the sexual response cycle that following an orgasm is the plateau phase, testosterone is released equally in men and women, a refractory period occurs in which people cannot experience orgasm, the feeling that accompanies an orgasm is stronger in men than in women.

The answer is the third one: a refractory period occurs in which people cannot experience orgasm.

Explanation for each option:

1. Following an orgasm is the plateau phase: This is incorrect. The sexual response cycle described by Masters and Johnson consists of four phases: excitement, plateau, orgasm, and resolution. The plateau phase occurs before orgasm, not after.

2. Testosterone is released equally in men and women: This is incorrect. While testosterone plays a role in sexual arousal for both men and women, it is not released equally. Men generally have higher levels of testosterone than women.

3. A refractory period occurs in which people cannot experience orgasm: This is correct. After an orgasm, particularly in men, there is a refractory period during which it is physiologically impossible to achieve another orgasm. This period varies in length from person to person.

4. The feeling that accompanies an orgasm is stronger in men than in women: This is incorrect. The subjective experience of orgasm can vary widely among individuals, and there is no scientific consensus that it is stronger in men than in women.

In summary, the correct answer is that a refractory period occurs in which people cannot experience orgasm.
