PeniMaster: Urological medical devices for penile enlargement, thickening and straightening.
PeniMaster medical products
PeniMaster are medical extenders that stretch the penis gently and painlessly over the long term to enlarge and straighten it. The plastic-cosmetic stimulation exerted on the tissue of the penis is also used to treat Peyronie's disease or before and after urological operations (e.g. removal of the prostate).
more about fields of application
Clinical Study 2019: Depending on the application intensity of PeniMaster PRO, the erect penis monthly can gain up to 1 centimeter / 0,4 inches in length and substantially in circumference. In addition, the penis can be significantly straightened.
PeniMaster PRO can be used overnight (read more).
Proof of performance
in the video: 7.6 kg pulling force* on the penis with PeniMaster PRO.
*For physiological and safety reasons, we recommend using a pulling force of up to approx. 1200 grams if the extender is used regularly!
A large-scale clinical study published in the renowned British Journal of Urology proved that: The PeniMaster PRO elongates the penis and allows for an effective and safe treatment of an abnormal curvature of the penis (Peyronie; IPP; Induratio penis plastica). The medical product is a quick and effective alternative to high-risk operations. The results cannot be transferred to another stretching device (extender) and only apply for the PeniMaster PRO.
PeniMaster PRO is a very well established and effective device, as it does not grip the shaft of the penis, but rather develops the pulling action purely via the tip of the penis and/or the glans. The unique glans chamber of the PeniMaster PRO fulfils this purpose excellently. It can even be worn under normal, everyday trousers.
PeniMaster PRO is not a normal vacuum device. Rather, it combines vacuum with other binding forces. As these holding forces supplement each other, a very secure fastening to the glans is possible, whilst at the same time minimising unwanted side effects. The extender really is very good.
