During exercises, the spongy tissues are stretched or expanded to increase their maximum blood capacity. A higher volume of blood leads to the formation of micro-tears in the surrounding smooth muscles. The body will repair these tears and encourage the growth of new cells. It’s the same principle that explains how bodybuilders gain new muscles when working out in the gym.
Depends. Some methods seem to be getting better responses than others. “Studies are being done to improve male girth through injections of hyaluronic acid, which is used as a filler (and is used in orthopedics to improve knee arthritis),” says Dr. Steve from SiriusXM's Weird Medicine on FactionTalk. (Here's a study that supports what Dr Steve is talking about). “The average vagina is 4 inches deep, so girth is much more likely to enhance pleasure for the woman than an increase of length, given that the average male penis length is approximately 5.5 inches,” says Dr. Steve.
Taking this amino acid can result in the increased blood flow, making the penis larger during erections. Some men reported to increase their penis size after taking this supplement for about 6 weeks. However, if you have problems with your heart health, you should not take this supplement. In fact, taking L-arginine is actually one of the best tips on how to make your penis bigger naturally and you should not look down this nutrient when it comes to increase your penis size naturally at home.
Stretching with weights. Weights or stretching exercises won't bulk up your penis -- it's not a muscle. But hanging weights off your flaccid penis may stretch it a bit, O'Leary says. The catch is that it requires a freakish degree of dedication. "You might have to wear a weight strapped to your penis eight hours a day for six months," says O'Leary. At the end of it, you could be lucky enough to gain about half an inch. Risks include tearing of the tissue, burst blood vessels, and other problems.
