Female Sexual Wellness Protocol: PT-141

Protocol Overview

PT-141 (Bremelanotide), marketed as Vyleesi, is the first and only FDA-approved treatment for acquired, generalized hypoactive sexual desire disorder (HSDD) in premenopausal women. Unlike previous treatments, PT-141 works through the central nervous system to increase sexual desire and arousal, independent of hormonal or vascular mechanisms.

What is HSDD?

Hypoactive Sexual Desire Disorder is characterized by:

• Persistently low or absent sexual desire
• Marked distress or interpersonal difficulty
• Not better explained by other conditions
• Not due to relationship problems or medications
• Affects approximately 10% of premenopausal women

Expected Benefits

• Increased sexual desire and arousal
• Enhanced sexual satisfaction
• Improved sexual experiences
• Reduced distress about low libido
• Better relationship satisfaction

How PT-141 Works

Mechanism of Action

PT-141 is a melanocortin receptor agonist that works through the central nervous system:

• MC4R activation: Stimulates melanocortin-4 receptors in the brain
• Hypothalamic effects: Modulates sexual desire centers
• Dopamine modulation: Enhances dopaminergic pathways
• Central arousal: Increases sexual desire independent of physical stimulation

Unique Advantages

• Non-hormonal: Doesn't affect estrogen or testosterone
• On-demand use: Take only when desired
• Central mechanism: Works through brain, not genitals
• No daily dosing: Use as needed before sexual activity
• Proven efficacy: Demonstrated in clinical trials

Frequently Asked Questions

How is PT-141 different from "female Viagra"?

PT-141 works through the brain to increase desire, while drugs like flibanserin (Addyi) or sildenafil work through different mechanisms. PT-141 is used on-demand rather than daily, and works through melanocortin receptors rather than serotonin or blood flow.

Will it work for postmenopausal women?

PT-141 is only FDA-approved for premenopausal women as it wasn't studied in postmenopausal populations. Efficacy and safety in postmenopausal women is unknown.

Can my partner use it too?

PT-141 is also used off-label for male erectile dysfunction and low libido, though it's not FDA-approved for men. Men would need their own prescription and medical evaluation.

How long can I use it?

Clinical trials studied PT-141 for up to 24 weeks. Long-term safety beyond this is not well established. Discuss ongoing use with your healthcare provider.
