Penile lengthening: what can realistically be expected?

Penile lengthening: what can realistically be expected?

Lengthening, thickening, flaccid, erect: the gains from a hyaluronic acid penoplasty differ depending on which axis is considered. Here, in concrete terms, is what can be expected — and what should no longer be hoped for.

Distinguishing the four possible gains

The first source of misunderstanding in consultation comes from a confusion: people speak of “enlarging the penis” as though it were a single objective, when in fact there are four distinct ones. Girth and length on the one hand, flaccid and erect states on the other: each combination corresponds to a different reality. Confusing them invites disappointment. Distinguishing them means setting accurate expectations.

The gains to expect

For a hyaluronic acid penoplasty, the gains to expect are as follows:

Girth, where the gain is real

It is on thickness that medical penoplasty gives its best results. The gain of 2 to 5 cm in girth shows both flaccid and erect, and visibly transforms the appearance. The exact extent depends on several factors — skin quality and elasticity, starting anatomy — that only a consultation can assess precisely.

Length, where candour is required

On length, the distinction between flaccid and erect is crucial. When flaccid, a gain of 1 to 3 cm is obtained simply through weight: the product makes the penis heavier, so it hangs lower. Penises that are highly retractile to begin with benefit most. When erect, by contrast, one must be clear: the gain is virtually nil. At most 1 cm if the penis was somewhat buried, or if the added thickness projects it slightly outwards. To promise lengthening when erect would be a lie — hyaluronic acid does not allow it.

No length gain when erect: a limit to be aware of before going ahead.

And the glans?

For the glans, one does not think in centimetres: the aim is a glans that is thicker and more engorged when erect. The glans is the first structure involved in penetration; treating it properly prevents it from being “outgrown” by a widened shaft, and contributes to the harmony of the whole. It is an aspect often overlooked, although it contributes fully to the quality of the result.
