• •Use of topical medications in the genital region that may interfere with PSI assessment as well as their absorption or drug interaction, including vaginal estrogens, lubricants, spermicides, creams or gels, vaginal douches;
• •History of symptomatic hypotension, or diseases that increase the risk of symptomatic hypotension, such as patient with heart disease (including history of angina and/or heart failure) and nephropathies;

• •ECG findings that are clinically symptomatic, or that, in the Investigator's judgment, are considered significant and pose a risk to the research volunteer's participation;
• •Findings on laboratory tests that, in the Investigator's judgment, are considered significant and offer risk to the research volunteer's participation or may hinder the study analyses;
• •TSH outside the normal range for age and/or participants with hypothyroidism who started thyroid hormone replacement less than 3 months ago, even if TSH is within normal limits;
• •BP outside safe limits: SBP below 90 mmHg or above 170 mmHg; or DBP below 50 mmHg or above 100 mmHg, except for situations such as "white coat" syndrome;

• •Pregnant or lactating;
• •Current use of nitric oxide donors, guanylate cyclase stimulators (e.g. Riociguat), or 5- phosphodiesterase inhibitors (Sildenafil, Tadalafil, etc.);
• •Any disease or condition or physical finding that the Investigator considers significant and that increases the risk of the research participant's participation or may interfere with the results, including serious debilitating diseases, presence of cancer, serious mental illness, persistent abuse of medication;
