Penis enlargement, or male enhancement, is any technique aimed to increase the size of a human penis. Some methods aim to increase total length, others the shaft's girth, and yet others the glans size. Techniques include pills, hormones, massage, stretching, inflation, incision, injections, and implants. While some techniques are hoaxes, others may be somewhat effective, perhaps at high risk of complications.
Platelet-rich plasma (PRP) has been used clinically in humans since the 1970s, and the healing properties of PRP have been attributed to the secretory proteins and autologous growth factors that may enhance the healing process at a cellular level. It’s also been found to enhance the differentiation, recruitment, and proliferation of cells that are involved in tissue regeneration . Through the years, researchers have found many different uses for PRP, studying it in the skin healing process  and as a symptom- and disease-modifying treatment for osteoarthritis .
Commonly called a "penis pump", a vacuum erection device, or VED, creates negative pressure that expands and thereby draws blood into the penis. Medically approved VEDs, which treat erectile dysfunction, limit maximum pressure, whereas the pumps commonly bought by consumers seeking penis enlargement can reach dangerous pressure, damaging penis tissue. To retain tumescence after breaking the device's airtight seal, one must constrict the penis' base, but constriction worn over 30 minutes can permanently damage the penis and cause erectile dysfunction. Although vacuum therapy can treat erectile dysfunction sufficiently to prevent penis deterioration and shrinkage, clinical trials have not found it effective for penis enlargement.
Penile enlargement pills and patches are devices that you see advertised on-line lots. They promise to become very convenient and discreet solutions if you need to make your penis bigger. However, you have to be conscious of research about the efficacy of those pills and patches are consistent in showing that these pills are ineffective and they are purely offered for profit. Every current brand of pill I know of may also be not FDA approved, so anybody’s researching their claims of safety and efficacy.
That’s usually because they’re not getting enough blood flow to the penis, which could be the result of being overweight, smoking, increased cholesterol, high blood pressure, diabetes, or cardiovascular disease. So the first step in your penis-growing experiment should be to get the rest of your body healthy — especially your cardiovascular system. “What’s good for the heart is good for the penis,” says Fisch.
You can also try penis traction, a clinically tested method with a penis extender. “A penis extender applies traction to your penis and stretches it over a longer period of time — up to six hours per day. The constant stretch to which the penis is exposed, called cytokinesis, causes natural cell division, which results in a longer and thicker penis,” says Stacy Rybchin, founder & CEO of My Secret Luxury. Once your cells have grown and your penis size has increased, you will keep your extra penis length and girth forever.
