A condition characterized by the formation of scar tissue in the penis, potentially caused by long-term use of penis pumps.
Penile traction devices (PTDs) have accumulating randomized and meta-analytic evidence showing modest but clinically meaningful improvements in penile curvature and length for selected men with Peyron...
A penis that is significantly larger than average can cause a mix of physical, sexual, relationship and practical complications — from pain during intercourse and condom fit issues to psychological di...
A small but clear body of clinical reporting and reviews indicates that unsafe or excessive use of vacuum/traction devices can injure penile tissues and, in at least one documented case, appear to hav...
Vacuum erection devices (VEDs) are a well-established, generally safe mechanical treatment for erectile dysfunction, but several medical conditions and practical limitations can make their use risky o...
Penile traction therapy (PTT) appears most effective in men with less-severe, non‑calcified Peyronie’s plaques, lower baseline curvature (commonly 50° and reporting better responses in those with less...
from medical causes is uncommon and usually stems from true biological changes (), deliberate medical or cosmetic interventions (), or transient changes from vascular events; much of what people inter...
Improper use of penis pumps commonly produces superficial injuries — bruising, petechiae (pin‑point bleeding), blistering, numbness and temporary discoloration — and, less frequently, more serious eve...
Penile curvature can be a normal anatomical variant or the result of Peyronie’s disease, a fibrotic disorder of the tunica albuginea that creates palpable plaques, pain and deformity during erection ....
Urologists approach medication-induced penile shortening by first distinguishing mechanism—vascular hypoxia and fibrosis from androgen-deprivation or radiotherapy, neural or anatomic change after pros...
Penile traction induces tissue remodeling through mechanotransduction: sustained longitudinal strain is sensed by cells in the tunica albuginea and corpora cavernosa, triggering biochemical cascades t...
The FDA’s Class II special controls guidance for external penile rigidity devices emphasizes design safeguards (notably a manual quick‑release for vacuum pumps), clear labeling and contraindications, ...
Girth can and does change over time for many men: the most decisive windows are prenatal development and puberty, but measurable changes continue across adulthood due to health, hormonal, and mechanic...
Hormonal changes—chiefly a gradual decline in bioavailable testosterone and increases in sex-hormone binding globulin (SHBG)—contribute to reduced penile fullness and modest loss of girth in many agin...
Penis pumps (vacuum erection devices) are effective and noninvasive for many men, but several medical conditions and medications make their use risky or warrant physician clearance beforehand; the pri...
FDA‑cleared vacuum erection devices (VEDs) are medical-grade tools intended and tested for erectile dysfunction and penile rehabilitation and usually include safety features and clear clinical guidanc...
Home penis‑stretching — from manual “jelqing” to weights, vacuum pumps and traction extenders — is promoted online as a low‑cost route to length or to treat curvature, yet the clinical record shows a ...
No credible evidence shows that "initiation school" practices — interpreted in reporting as manual penis-stretching routines like jelqing or similar exercises — produce permanent increases in penile l...
Larger penile circumference can increase friction, the likelihood of mucosal injury, and the chance that penetration is uncomfortable or painful for a receiving partner, particularly when lubrication,...
Penile traction therapy (PTT) is generally reported as a well-tolerated, noninvasive option for men with Peyronie’s disease and post-prostatectomy penile shortening, with most trials documenting only ...
