Penile hypercoagulability during erection: a possible predisposing factor to ageing penile vascular changes.
British Journal of Urology
|April 1, 1986
Summary
Penile erection causes blood to become more likely to clot, with fibrin depositing on blood vessel walls. This suggests increased penile blood clotting may contribute to age-related vascular changes.
Area of Science:
- Reproductive biology
- Vascular physiology
- Hematology
Background:
- Penile vascular health is crucial for erectile function.
- Age-related vascular changes can impair erectile function.
- Haemostatic mechanisms during erection are not fully understood.
Purpose of the Study:
- To investigate haemostatic changes in penile and systemic blood during erection.
- To determine the role of hypercoagulability in penile vascular changes.
Main Methods:
- Studied haemostatic changes during erection in Chacma baboons.
- Analyzed penile and systemic blood for clotting factors.
- Examined penile vasculature for fibrin deposition.
Main Results:
- Dynamic hypercoagulability was observed in penile blood during erection.
- Fibrin deposition occurred on the endothelium of the penile artery and trabeculae.
- Systemic blood showed different haemostatic patterns compared to penile blood.
Conclusions:
- Penile hypercoagulability during erection is a significant finding.
- Fibrin deposition suggests a pro-thrombotic state in the penile vasculature.
- Penile hypercoagulability may predispose to age-related penile vascular alterations.
