    Abstract:

    Summary Penile duplex Doppler ultrasound (PDDU) assesses the etiology of erectile dysfunction. Peak systolic velocity (PSV), end-diastolic velocity (EDV), and resistive index (RI) are common PDDU parameters. We assessed whether stretched penile length (SPL) in the flaccid state and measured penile length at peak erection after intracavernosal injection (ICI) of a Vasodilator during PDDU correlated with the etiology of erectile dysfunction. We performed a retrospective review of 93 patients who underwent PDDU for erectile dysfunction. Normal and stretched penile length were measured, both at a flaccid state prior to ICI and at peak erection during PDDU. Collected data included patient demographics, vascular, and anatomic parameters. The mean age was 52 years. SPL was equivalent to peak penile length after ICI in 60 patients (65%, group 1) and did not match in 33 (35%, group 2). There were no significant differences between the two groups in terms of flaccid, stretched, and post-ICI erect penile lengths, IIEF score, PSV, percent rigidity or tumescence, and Vasodilator dose used. Patients in group 2 had less of a change in penile length from flaccid to erect state (36% vs. 44%, p = 0.02), higher EDV (12.0 vs. 8.5, p = 0.041), lower RI (0.6 vs. 1.0, p = 0.046), and more veno-occlusive dysfunction (82% vs. 53%, p = 0.001). On multivariate analysis, failure to reach maximum SPL at peak ICI erection (OR 2.255, CI 1.191–4.271, p = 0.0126), EDV (OR 1.281, CI 1.115–1.471, p < 0.001) and RI (OR 0.694, CI 0.573–0.723, p = 0.009) predicted veno-occlusive dysfunction. Failure to reach maximal SPL during PDDU using ICI with a Vasodilator Agent predicted veno-occlusive dysfunction, which is independent of both penile rigidity and tumescence. This measurement could serve as another diagnostic tool for predicting veno-occlusive dysfunction when PDDU is not readily available. Limitations include the subjective nature of penile measurements and different PGE1 doses used.

    Abstract:

    INTRODUCTION AND OBJECTIVES: Men who are considering vasectomy as a means of contraception may harbor significant anxiety regarding their future sexual potency. As a result, couples may choose other forms of contraception with lower efficacy. While prior studies have demonstrated high satisfaction rates after vasectomy, no study to date has provided an objective measure of sexual function after vasectomy. Therefore we sought to determine the impact of vasectomy on the frequency of sexual intercourse. METHODS: We analyzed data from cycles 6 (2002) to 7 (20062008) of the National Survey of Family Growth (NSFG) to compare the frequency of sexual intercourse (within the prior 4 weeks) for men who had undergone vasectomy versus those who had not. We excluded men who had never had sex, as well as men under the age of 30, since vasectomy prior to this age is less common. We then constructed a multivariate logistic regression model to adjust for age, marital status, race, education, health, BMI, children, and income. RESULTS: A total number of 3798 men met the criteria for our study; 317 (8.3%) had undergone vasectomy. For men who had undergone vasectomy, the average frequency of sexual intercourse was 5.8 times per month compared to 4.8 times per month for nonvasectomized men. Only 6% of vasectomized men did not have sexual intercourse in the prior 4 weeks, compared to 16% of nonvasectomized men. In addition, 66% of vasectomized men and 53% of non-vasectomized men had sexual intercourse at least once a week. After adjusting for demographic, socioeconomic, reproductive, and health factors, men utilizing vasectomy had a 77% higher odds (95% CI 2-205%) of having sexual intercourse at least once a week, versus less than once a week. CONCLUSIONS: Vasectomy does not adversely impact sexual frequency. This finding may be helpful to couples as they consider their contraceptive options.

This measurement could serve as another diagnostic tool for predicting veno-occlusive dysfunction when PDDU is not readily available. Limitations include the subjective nature of penile measurements and different PGE1 doses used.

    Abstract:

    Summary Penile duplex Doppler ultrasound (PDDU) assesses the etiology of erectile dysfunction. Peak systolic velocity (PSV), end-diastolic velocity (EDV), and resistive index (RI) are common PDDU parameters. We assessed whether stretched penile length (SPL) in the flaccid state and measured penile length at peak erection after intracavernosal injection (ICI) of a Vasodilator during PDDU correlated with the etiology of erectile dysfunction. We performed a retrospective review of 93 patients who underwent PDDU for erectile dysfunction. Normal and stretched penile length were measured, both at a flaccid state prior to ICI and at peak erection during PDDU. Collected data included patient demographics, vascular, and anatomic parameters. The mean age was 52 years. SPL was equivalent to peak penile length after ICI in 60 patients (65%, group 1) and did not match in 33 (35%, group 2). There were no significant differences between the two groups in terms of flaccid, stretched, and post-ICI erect penile lengths, IIEF score, PSV, percent rigidity or tumescence, and Vasodilator dose used. Patients in group 2 had less of a change in penile length from flaccid to erect state (36% vs. 44%, p = 0.02), higher EDV (12.0 vs. 8.5, p = 0.041), lower RI (0.6 vs. 1.0, p = 0.046), and more veno-occlusive dysfunction (82% vs. 53%, p = 0.001). On multivariate analysis, failure to reach maximum SPL at peak ICI erection (OR 2.255, CI 1.191–4.271, p = 0.0126), EDV (OR 1.281, CI 1.115–1.471, p

    Abstract:

    INTRODUCTION AND OBJECTIVES: Men who are considering vasectomy as a means of contraception may harbor significant anxiety regarding their future sexual potency. As a result, couples may choose other forms of contraception with lower efficacy. While prior studies have demonstrated high satisfaction rates after vasectomy, no study to date has provided an objective measure of sexual function after vasectomy. Therefore we sought to determine the impact of vasectomy on the frequency of sexual intercourse. METHODS: We analyzed data from cycles 6 (2002) to 7 (20062008) of the National Survey of Family Growth (NSFG) to compare the frequency of sexual intercourse (within the prior 4 weeks) for men who had undergone vasectomy versus those who had not. We excluded men who had never had sex, as well as men under the age of 30, since vasectomy prior to this age is less common. We then constructed a multivariate logistic regression model to adjust for age, marital status, race, education, health, BMI, children, and income. RESULTS: A total number of 3798 men met the criteria for our study; 317 (8.3%) had undergone vasectomy. For men who had undergone vasectomy, the average frequency of sexual intercourse was 5.8 times per month compared to 4.8 times per month for nonvasectomized men. Only 6% of vasectomized men did not have sexual intercourse in the prior 4 weeks, compared to 16% of nonvasectomized men. In addition, 66% of vasectomized men and 53% of non-vasectomized men had sexual intercourse at least once a week. After adjusting for demographic, socioeconomic, reproductive, and health factors, men utilizing vasectomy had a 77% higher odds (95% CI 2-205%) of having sexual intercourse at least once a week, versus less than once a week. CONCLUSIONS: Vasectomy does not adversely impact sexual frequency. This finding may be helpful to couples as they consider their contraceptive options.
