The Instant Male Pill

Product Overview

Alternative Name: Clean Sheets Pill, Inhibition of Vas Propulsive Contractility

Development Status: Active Development

Target: Male

Mode: Non-hormonal

Delivery Type: Oral

Duration Type: Short-acting

Description: The coordinated contractions of longitudinal and circular muscles in vas deferens provide the propulsion that sustains transport of spermatic fluid and ensures emission. The Instant Male Pill suppresses this propulsive function by inactivating contractility of longitudinal muscle in vas deferens but not circular muscle contraction. This leads to closure of vas deferens lumen and inhibition of emission, crucially without affecting ejaculatory activity and coincident sensation of orgasm. Inhibition of semen emission has the potential to reduce transmission of semen-borne pathogens such as HIV.
