Chapter 10, Problem 10TY

Summary Introduction

Introduction:

Researchers Masters and Johnson identified four phases of a sexual-response cycle. Excitement, plateau, orgasm, and resolution are the four stages in sexual-response.

Answer to Problem 10TY

Correct answer:

The refractory period is that time during which a man cannot have another erection. This information is reflected in the option “b”. Therefore, option b. is correct.

Option b. is given as “a man cannot have another erection”.

Explanation of Solution

Reason for the correct statement:

Resolution phase is the final phase in sexual response which involves body returning back to its normal state as it was before arousal. In females clitoris retracts, the color of vaginal lips return back to normal, and the vaginal lips close. In males, testes descend back, and erection is lost. Men also have a refractory period, which lasts from several minutes to hours during which they cannot reach another erection. Refractory period extends with the age of men. The older a man gets, the longer is the refractory period.

Hence, option b. is correct.

Reasons for the incorrect statements:

Option a. is given as “a woman cannot have another orgasm”.

Women can achieve several orgasms if stimulated. The refractory period is not a period in which women cannot achieve another orgasm. Hence, it is a wrong answer.

Option c. is given as “a man can be erect but not have an orgasm”.

Men can have an only a single intense orgasm. In refractory period men cannot achieve another erection. Hence, it is a wrong answer.

Option d. is given as “a woman cannot be aroused”.

Women do not have a refractory period and can achieve another set of orgasm. Hence, it is a wrong answer.

Hence, options a., c., and d. are incorrect.

Conclusion

The time duration during which men cannot achieve another orgasm is called the refractory period.
