Abstract

An apparatus for providing a vibratory stimulus to the penis of a male human comprising a cuff adapted to fit around the penis, which cuff includes one or more vibratory means operable at a pre-determined or variable frequency. A method of measuring premature ejaculation in a male human, said method comprising the steps of: a) positioning a vibratable cuff to the penis of the human; b) providing a vibratory stimulus having either a pre-determined constant frequency or a variable frequency to induce ejaculation; c) measuring the latency time period to ejaculation at said vibratory stimulus and/or the threshold frequency required to induce ejaculation; and d) comparing said latency measurement and/or said threshold frequency to known standard measurements. A method of evaluating a novel potential therapeutic agent for the treatment of premature ejaculation in a male patient. Initial assessment of premature ejaculation can be made as a baseline measurement, and then novel potential therapeutic agents administered to the patients.

Claims

1. Apparatus for providing a vibratory stimulus to the penis of a male human comprising:

a cuff adapted to fit around the penis, which cuff includes one or more vibratory means operable at a pre-determined or variable frequency; and

sensor means adapted to be fitted to the penis and to detect ejaculation and calculate an event duration comprising the time period between the commencement of stimulation and ejaculation.

2. Apparatus as claimed in claim 1, further including control means for controlling the operation of said vibratory means.

3. Apparatus as claimed in claim 2, wherein said control means is adapted to control the intensity of vibration of said vibratory means.

4. Apparatus as claimed in claim 2, wherein said control means is further adapted to control the operation of said vibratory means such that the vibratory means is repeatedly switched alternately on for a first predetermined time period and off for a second predetermined time period.

5. Apparatus as claimed in claim 1, wherein said sensor means is a pulse sensor.

6. Apparatus as claimed in claim 1, further including data storage means adapted to record at least one of data generated by said sensor means, parameters relating to the operation of said vibratory means, and an event duration.

7. Apparatus as claimed in claim 1, further including visual display means for displaying at least one of parameters relating to the operation of the apparatus, data, and at least one elapsed time period.

8. Apparatus as claimed in claim 1, further including interface means whereby the apparatus may communicate with a separate data processing system.

10. The method of claim 9, comprising the step of positioning the apparatus as claimed in claim 1 to the penis of the human.

17. The method of claim 13, comprising the step of positioning the apparatus as claimed in claim 1 to the penis of the patient.

9. A method of measuring premature ejaculation in a male human, said method comprising the steps of:

a) positioning a vibratable cuff to the penis of the human;

b) providing a vibratory stimulus having either a pre-determined constant frequency or a variable frequency to induce ejaculation;

c) measuring the latency time period to ejaculation at said vibratory stimulus and/or the threshold frequency required to induce ejaculation; and

d) comparing said latency measurement and/or said threshold frequency to known standard measurements.

11. The method of claim 9, comprising the step of comparing said latency measurement and/or said threshold frequency to known standard measurements to diagnose premature ejaculation.

12. The method of claim 11, wherein a shorter latency time period and/or lower threshold frequency when compared to standard measurement is an indication of premature ejaculation condition.

13. A method of evaluating a novel potential therapeutic agent for the treatment of premature ejaculation in a male patient said method comprising the steps of:

(a) providing a first measurement of the latency time period to ejaculation and/or the threshold frequency required to induce ejaculation in said patient by;

i) positioning a vibratable cuff to the penis of said patient;

ii) providing a vibratory stimulus having either a pre-determined constant frequency or the threshold frequency required to induce ejaculation; and

(iii) measuring the latency to ejaculation at either said constant vibratory or at said threshold frequency required to induce ejaculation;

(b) administering said agent to said patient;

(c) at a pre-determined time providing second measurement of the latency time period to ejaculation and/or of the threshold frequency required to induce ejaculation as described in the steps (i) to (iii) above; and

(d) comparing said first and second measurements to determine the efficiency of said agent.

14. The method of claim 13, wherein step (c) is repeated at different periods of time to obtain several measurements.

15. The method of claim 13, wherein efficiency of said agent is shown by an increase of either the latency time period or the frequency of vibratory stimulus to induce ejaculation of the second measurement when compared to the first measurement.

16. The method of claim 15, wherein said increase is at least of 50%.
