This guide will answer the following questions:
1. What is the average penis length and girth?
2. How much does penis size matter in relationships? (Also, which is more important, length or girth?)
3. What is the ideal penis size?
4. How can penis size be increased? Evidence will be attached.
A large 2020 scientific review, based on 10 studies with 1629 participants, in which measurements were taken by researchers rather than by the men themselves found the average erect penis length to be 13.61 cm(5,36")
According to a meta-analysis of 20 studies, the average girth of the erect penis was 11.66 cm (4.59").
IMPORTANT TO UNDERSTAND: these studies include both different ethnic groups and older participants, so the averages are probably underestimated compared with the average sizes of the younger generation of europeans. I recommend checking out this calculator: It was built on many studies and accounts for racial differences.
The first survey included 1,387 sexually active women.
1. According to this survey, 91.2% of women say size matters for sexual pleasure.
2. A penis length of 18.34 cm (7.22 inches) is considered the most ideal
3. 40% women admitted they may cheat on a partner because of a small penis (10% said they would definitely cheat)
3.1. 30% women might cheat on their partner because of a penis that is too large (only 5.6% said they would definitely cheat)
Therefore, having a penis that is too large is far better than having a penis that is too small.
4. The ideal penis girth is 5.94 inches or 15 cm.

TLDR for the first survey:
Penis size matters so much that 40% admitted they might cheat on you if your penis is small enough.
Ideal penis length 7.22 inches (18.3 cm) and the ideal penis girth is 5.94 inches (15 cm)
- Long-term partner: length 16.0 cm, girth 12.2 cm
- Short-term partner: length 16.3 cm (6.4"), girth 12.7 cm (5")
Also, in answer to the question of whether length or width matters more, it is width. The outer third of the vagina is considered the most sensitive because of the high density of nerve endings, so thickness plays the most important role.
EXTENDERS
Pros | Cons |
The best supported non surgical method | Requires a lot of time (4–6 hours/day) |
FDA approved | No noticeable increase in girth |
Improves erection quality | |
Helps correct curvature | |
Very safe | |
Evidence:
After 6 months, the average increase in penis length was 1.7 ± 0.8 cm in the flaccid state, 1.3 ± 0.4 cm in stretched length, and 1.2 ± 0.4 cm in erect length. In addition, of 13 patients with mild erectile dysfunction, 9 had normal erectile function after 9 months.
n=23 (26.5 ± 8.1 years): flaccid length increased from 8.8 to 10.1 and 10.5 cm over 1–3 months

Pros | Cons |
Cheap | High risk of injury |
Results are often similar to or slightly better than an extender, with less time per session | Bruising and numbness are common |
| No clinical evidence |
Evidence:
Unfortunately, no matter how much I looked, I could not find penis enlargement results obtained exclusively from hanging, because people usually combine this technique with other methods such as extenders, pumps, jelqing, etc. Still, the mechanics are very similar to an extender, and there are many results that involved this technique.
Here are a couple of such results from Reddit:
1. A combination of extender and hanging. 1.7 cm in a year
2. +2.5 cm in 6 months
3. 5 cm over 3 years using hanging and pumps

JELQING
A manual practice of stretching the penis by hand in order to increase its length and/or thickness through mechanical pressure.
There are many different manual techniques.

Pros | Cons |
FREE | No clinical evidence |
Requires no recovery time | Risk of injury |
No equipment | Results vary widely (probably due to a lot of people doing them incorrectly) |
Evidence:
1. 2.5 cm in 2 years using only manual techniques
2. 2.5 cm in 1 year
3. 0.7 cm in 2 months

REDUCING SUPRAPUBIC FAT
This is pretty self-explanatory, but I still see no reason not to mention this method. Your penis will not actually grow, but by reducing suprapubic fat it will look larger visually.

The safest method | |
0 risk of injury to the penis | |
Evidence:
PENIS PUMPS
Creates negative pressure (vacuum) to draw blood into erectile tissue and cause enlargment.
Creates negative pressure (vacuum) to draw blood into erectile tissue and cause enlargment.
Pros | Cons |
FDA approved | Excessive and intense use can cause a weak erection by damaging tissue |
Improves erectile function | There is a chance of a small subcutaneous bleed. This can temporarily cause tiny red dots on the penis. |
Although it is aimed at increasing girth, it also helps with length | Immediately after a session, the erection may temporarily feel less hard than a natural one |
Helps with curvature |
Evidence:
1. n=31: after 12 weeks of vacuum therapy, 11 men saw an increase in stretched penis length of an average of 0.5 cm (to 1.5 cm), and in 21 of 31 patients the curvature angle decreased by 5–25°
2. A substantial increase in penis girth using a pump (I do not believe his measurements)
3. 2 cm to girth
There is also a water pump/hydropump. The mechanism is the same, but it works by filling with water and is used in the shower or bath. Pressure is distributed more evenly than in air pumps.
More expensive than air pumps.

LIGAMENTOLYSIS
The ligament that attaches the penis to the pubic bone is surgically cut. This releases the internal part of the penis. In my opinion, this may be the worst procedure on the list because there is no increase in erect length and there are many risks. But because the procedure is popular, I decided to include it.

Pros | Cons |
Permanent increase in flaccid length | The erection angle changes significantly (it may point downward) |
The most studied surgical lengthening procedure | If the ligament is cut, penile instability during sex is possible |
Average flaccid length gain is 2–5 cm | Erect length does not increase |
| After surgery, months of extender use are mandatory |
SILICONE IMPLANT (PENUMA)
A soft silicone implant is placed under the skin of the penis through a small incision in the scrotal area under general anesthesia. It increases both girth and flaccid length, but does not affect erect length

Pros | Cons |
FDA approves | Expensive |
Permanent and predictable result | If uncircumcised, circumcision is required |
Does not affect erectile function | Erect length does not increase |
Reversible, can be removed | Removal leaves scars |
Feels natural to the touch (soft silicone) |
AUTOGENOUS FAT TRANSFER
Fat is taken from the abdomen or thighs via minor liposuction and then injected into the shaft of the penis
Fat is taken from the abdomen or thighs via minor liposuction and then injected into the shaft of the penis
Pros | Cons |
The body’s own tissue is used, so an allergic reaction is impossible | Unpredictable resorption (30–50%) over 3-6 months |
Theoretically lasts longer than HA | Uneven fat nodules are the most common complaint |
| Risk of an uneven, lumpy appearance |
| Irreversible |
Hyaluronic acid (HA) filler
The gold standard for non-surgical girth enlargement. 100% reversible with the enzyme hyaluronidase
Pros | Cons |
The safest injectable option | Temporary, resorbs over 12–18 months |
Immediate visible result | Asymmetry/lumps are possible |
Feels natural when done well | The filler may migrate to the foreskin |
Minimal recovery (24–48 hours) | Maintenance costs to keep the result |
Very high patient satisfaction |
Poly-L-lactic acid (PLLA) filler
Over time, it stimulates the body’s own collagen production, gradually increasing volume. The result appears more slowly than HA (over weeks), but lasts longer. Girth gains are comparable to HA in direct randomized studies
Pros | Cons |
Lasts longer than HA (18–36 months) | Irreversible (there is no enzyme to dissolve it) |
Stimulates the body’s own collagen | The result is slower than HA |
Biodegradable, the body metabolizes it | |
Gradual, natural result | |
Evidence:
1. It was hard to find visual proof of this method, but here is a clinic blog that performs this practice.
2. A clinical study that compared 3 different fillers
3. A study that compared HA and PLA

PMMA
This creates a permanent volume that cannot be dissolved because the body encapsulates the particles in fibrous tissue. It gives the largest girth gain among injectable methods, but also the highest risk. Irreversible.
Pros | Cons |
Permanent result, with no repeat procedures | Irreversible |
The largest injectable girth gain | Lumps are very difficult to treat |
| If infection occurs, there is a risk of amputation |
| Feels firmer and less natural than HA |

Lastly:
I recommend this doctor’s youTube channel dedicated to penis length and girth enlargement. Tons of useful info.
Also, the subreddit r/gettingbigger. You will find tons of useful info, such as which extender to buy, which pump to use, various results, etc.
