2. Male
3. Confirmed diagnosis of idiopathic Parkinson’s disease for at least 3 years according to the UK Brain Bank criteria
4. On a stable regimen of anti-parkinson medication (such as L-Dopa, Amantadine, Anticholinergics, COMT inhibitors, dopamine agonists and MAO-B inhibitors) for at least three weeks prior to screening and willing to continue the same doses and regimens during study participation
5. Any other current and allowed prescription/ non prescription medications and/or nutritional supplements taken regularly must have been at a stable dose and regimen for at least three weeks prior to screening, and participants must be willing to continue the same doses and regimens during study participation
6. Able and willing to sign a current IRB-approved informed consent form
7. Acceptable method of contraception
Inclusion criteria for healthy controls:

Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 60
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range 16
Exclusion criteria for participants with PD:
1. Participants taking prostaglandins and/or vasoconstrictors/sympathomimetics (eg. COPD/asthma medication such as salbutamol, fenoterol; inotropics such as dobutamin; rhinitis therapy such as ephedrine), as oxytocin can interact with these drugs

3. Known allergy or hypersensitivity to any component of the IMPs
4. Females
5. Atypical or secondary parkinsonism (such as vascular Parkinsonism, drug induced Parkinsonism, Wilson’s disease, Alzheimer’s disease and Creutzfeld-Jacob disease)
6. Known abnormality in CT or MRI brain imaging which is considered to cause neurological symptoms or deficits
7. Concurrent dementia defined by MMSE =24
8. Presence of an acute or chronic major psychiatric disorder (e.g., hallucinations, agitation, paranoia)
9. History of severe cardiac disease (Angina, myocardial infarction, atrial fibrillation or cardiac surgery in the preceding two years)
10. History of end stage kidney or liver disease
11. Any other uncontrolled disease or any disease considered relevant by the investigator
12. Nicotine consumption of more than 10 cigarettes per day
13. Known allergy or hypersensitivity to latex rubber, due to possible cross-reactions
14. Patient is legally incapacitated or persons held in an institution by legal or official order
15. Persons with any kind of dependency on the investigator or employed by the Sponsor or investigator
Exclusion Criteria for healthy controls:
