What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Effect of IPDE (Tadalafile) according to FSFI (Female Sexual Function Index) | To determine the effect of IPDE at a dose of 1.5 mg versus placebo in women with disorders of interest and sexual arousal using the FSFI (Female Sexual Function Index). FSFI contains 19 questions, with each questions with a value minimum of 0 and maximum of 6 points, beeing 0 the worst scenario y 6 the best scenario. | 14 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Comparative IPDE Vs placebo according to FSFI | To compare the effect of IPDE with respect to placebo in women with disorders of interest and sexual arousal using the FSFI (Female Sexual Function Index). FSFI contains 19 questions, with each questions with a value minimum of 0 and maximum of 6 points, beeing 0 the worst scenario y 6 the best scenario. | 14 weeks | 
| Comparaive of IPDE Vs placebo according NSSS-Short (New Sexual Satisfaction Scale) | To compare the effect of IPDE with respect to placebo in women with disorders of interest and sexual arousal using the questionnaire The New Sexual Satisfaction Scale (NSSS-Short). NSSS-Short (New Sexual Satisfaction Scale) contains 7 questions, with each questions with a value minimum of 0 and maximum of 100 points, beeing 0 the worst scenario y 100 the best scenario. | 14 weeks | 
| Comparative IPDE Vs placebo according to the TSQM (Treatment Satisfaction questionnaire for Medication) | To compare the effect of IPDE with respect to placebo in women with disorders of interest and sexual arousal using the Treatment Satisfaction questionnaire for Medication (TSQM) version 1.4. TSQM (Treatment Satisfaction questionnaire for Medication) contains 14 questions with each questions with a value minimum of 0 and maximum of 80 points, beeing 0 the worst scenario y 80 the best scenario. | 14 weeks | 
| Comparative of IPDE Vs placebo according to number of sexual events | To compare the effect of IPDE with respect to placebo in women with sexual interest and arousal disorder by measuring the number of sexual events recorded in the weekly diary. The diary will be fullfilled by the women according to the number of sexual events. | 14 weeks | 
| Comparative of IPDE Vs placebo according to the sexual satisfaction | To compare the effect of IPDE with respect to placebo in women with sexual interest and arousal disorder by measuring the sexual satisfaction of sexual intercourse. The scale will contain 3 questions, with a visual analog scale. This visual analog scale will contain a scale with different visual easy identificable progesion faces, from very sad face to very happy face, beeging the first sad face, the no satisfaction point, and the last very happy face the very satisfactory sexual event point. | 14 weeks | 
| Comparative of IPDE Vs placebo according to ease of arousal | To compare the effect of IPDE with respect to placebo in women with disorder of interest and sexual arousal by measuring the ease of arousal during sexual intercourse determined using an analog visual scale. The scale will contain 3 questions, with a visual analog scale. This visual analog scale will contain a scale with different visual easy identificable progesion faces, from very sad face to very happy face, beeging the first sad face, the no satisfaction point, and the last very happy face the very satisfactory sexual event point. | 14 weeks |
