Plastic 外科医s have 明らかにする／漏らすd the type of 後部-end Americans find most attractive.

The findings, from two 熟考する／考慮するs published in an academic 定期刊行物, show that,?size is not the most important factor when it comes to an?aesthetically pleasing derriere on women,?にもかかわらず the 'Kardashian 影響' on beauty 基準s.

In one 熟考する／考慮する, by 外科医s at Loma Linda University in California, 専門家s 新採用するd 1,100 men and women and asked them to?look at pictures of eight different 始める，決めるs of 女性（の） buttocks, which the doctors had digitally 生成するd.

They were then asked to 示す to 研究員s which one they 設立する the most attractive. Results showed that people 設立する 'waist to hip'?割合 of 0.65 most attractive. This number resulted in a more 狭くする waist that ゆらめくd わずかに into the hips.

WOMEN: The 後部-ends were 階級d from first place to last place based on how many 投票（する）s they received, with 1 存在 the most 望ましい and 8 存在 the least. The smaller numbers in the 底（に届く） left 示す the waist to hip 割合, which is the waist 測定 to your hip 測定

WOMEN: 専門家s 新採用するd 1,100 men and women and asked them to look at pictures of eight different 始める，決めるs of 女性（の） buttocks, which the doctors digitally 生成するd

WOMEN: The two least 望ましい buttocks were those with the largest (権利) and smallest (left) differences in hip/waist 割合s. The extreme hourglass 人物／姿／数字 seen on my A-名簿（に載せる）／表（にあげる） celebrities 階級d last place

But the ideal buttocks is far from the extreme 割合s seen on many A-名簿（に載せる）／表（にあげる） celebrity women famous for their hourglass 人物／姿／数字s.

In a separate 熟考する／考慮する 伴う／関わるing 2,000 men and women, 関係者s were shown five images of male buttocks and asked to 率 each from one to five ― with those 率d five 存在 the most attractive.

The male buttocks 階級d number one was also moderately sized, but the 輪郭（を描く）s of the muscle more defined.

Commenting on the 女性（の） results, Dr Marc Everett, a plastic 外科医 in New York City, told DailyMail.com: 'The 中央の-2010s brought an 爆発 in 人気 of? "Brazilian Butt 解除する" or BBL [a 手続き in which a doctor 移転s fat from the belly, hips or thighs to the buttocks].?

'But these days we are seeing より小数の 患者s requesting extreme results.

'Instead, they're going for more modest size fat 移転s, which put them into the "unsuspecting" or "it could still be natural" 部類.'

Kim Kardashian, pictured in 2017 and 2022, is arguably best known for her perfect hourglass curves. But the beauty has had a 変形 over the years and recently started 陳列する，発揮するing a more svelte 人物／姿／数字

Dr Everett 追加するs he's seen a 最近の 増加する in 患者s who want to 逆転する their 後部-高めるing 手続き.?

'I am seeing 患者s with some 悔恨 about their 誇張するd results,' he says.

'They are 捜し出すing 治療（薬）s for oversized buttocks that are いっそう少なく 流行の／上流の this １０年間, or for buttocks starting to 下落する 予定 to 高齢化.'

The 利益／興味 in BBLs was driven by large-後部d celebrities 含むing Khloe Kardashian, Cardi B and K.Michelle.

But with a 転換 in fashion many seem to have had the 外科 逆転するd, with Khloe Kardashian appearing in 2022 with a slimmed-負かす／撃墜する 人物／姿／数字.?

These are the five BEST looking pairs of breasts?

研究員s asked men to 階級 breasts to 明らかにする／漏らす which were most 控訴，上告ing.?

The 手続きs have 殺到するd in 人気, with the number of BBLs rising from nearly 4,000 in 2011 to 61,000 in 2021.

In the first 熟考する／考慮する, scientists began digitally altering a 在庫／株 image of a pair of 女性（の） buttocks to create eight images with 変化させるing waist-to-hip 割合s.

This is the main determinant of butt size ― along with the 量 of 団体／死体 fat inside the buttocks?― and?made the computer-生成するd images appear to have 変化させるing 容積／容量 in buttock tissue.

The larger a person's waist-to-hip 割合, the more fat they had around their waist, making their behind appear いっそう少なく curvy, scientists said.

And the smaller the waist-to-hip 割合 the いっそう少なく fat they had around their waist, making their buttocks appear curvier.

The images were then shown to 1,000 熟考する／考慮する 関係者s 新採用するd 経由で social マスコミ.

Almost all 関係者s were from the US ― half male, half 女性（の）, and the 大多数 were 老年の 25 to 34 years old.

研究員s 設立する the buttocks with a waist-to-hip 割合 of 0.65 was most popular.?Forty-four パーセント of 回答者／被告s said this was their preferred 選択.

A 割合 of 0.65 means that the buttocks is about 35 パーセント larger than the waist. It was 手段d by wrapping a tape 手段 around the waist at its smallest point and the hips at their largest point.

In second place was the わずかに smaller 割合 of 0.60: a ４半期/4分の1 of the 見本 好意d this size.?

One in 10 関係者s liked the second largest butt the best ― 0.675. And the butt considered least attractive had the lowest waist-to-hip 割合 of 0.55.

There is variation in waist-to- hip 割合s across the 全住民, doctors said, but anything at 0.6 or below would be 'hard to play off' as natural.

Every image shown got a 投票（する） from at least one of the 1,000 関係者s who said that was their preferred waist-to-hip 割合. Preferences in other 地域s of the world may 異なる.?

研究員s 設立する there were no 重要な differences between age groups, genders and 民族の groups ーに関して／ーの点でs of which buttocks they preferred.

令状ing in the 熟考する／考慮する published in the peer-reviewed 定期刊行物 of Plastic and Reconstructive 外科, they said: 'Our 熟考する／考慮する 設立する that a lower waist-to-hip 割合 was preferred in comparison to the often-特記する／引用するd 0.7.

'Only 5.7 パーセント of 回答者／被告s thought 0.7 was the most attractive waist-to-hip 割合.

'This may be a consequence of 目だつ （危険などに）さらす and desensitization of the general 全住民 to reality 星／主役にするs and celebrities with curvier 人物／姿／数字s.'

Dr Everett said a waist-to-hip 割合 from 0.6 and below was 'pretty 誇張するd' and 'hard to play off as natural'.?

MEN: The 後部-ends of men were 階級d from first place to last place based on how many 投票（する）s they received, with 1 存在 the most 望ましい and 5 存在 the least. 熟考する／考慮する 関係者s appeared to prefer muscular buttocks that had 鮮明度／定義?

MEN: Those which were more padded and curvy 得点する／非難する／２０d the worst - かもしれない because they appear more feminine

In the 熟考する／考慮する on male butts, 研究員s asked 2,000 people to 率 five 数字表示式の images of a male buttocks from three angles: Behind, at a curve and 味方する on.

The 関係者s 階級d the images from 1 to 5 with 5 存在 the most attractive and their 得点する／非難する／２０s were then 連合させるd to get an 全体にわたる 人物／姿／数字.?

関係者s were 新採用するd online and 61 パーセント were male 老年の between 25 and 34 years old.?

They were all in the 部隊d 明言する／公表するs and half of the 関係者s were from a white background while 75 パーセント were 異性愛の.?

Cardi B 明らかにする／漏らすd in 2022 that she had had butt fillers taken out of her behind. She is shown, left, in July, and, 権利, later in the year after telling fans she had had them 除去するd

Results showed that, 全体にわたる, 関係者s preferred a buttocks that was 'moderately 高めるd' and '井戸／弁護士席-割合d' in 外見.

Dr Ashit Patel, a plastic 外科医 in North Carolina who led the 熟考する／考慮する, said: 'In our 調査する, raters thought the ideal male buttocks shouldn't be too wide and should 保持する the characteristic dimple on the 味方するs.'

Results showed that from behind, a gluteal trochanteric 索引 (GTI) of 0.66 was most popular ― with an 普通の／平均（する） 得点する／非難する／２０ of 3.1.

The GTI was 手段d by dividing the distance from the thinnest point of the waist to the 底（に届く） of the buttocks by the widest point of the buttocks.?

研究員s said they used this on men instead of the waist-to-hip 割合 because of differences in fat 配当 between the two genders.

A 割合 of 0.66 means the buttocks is about 34 パーセント larger than the distance from the waist to the 底（に届く） of the behind.

Khloe Kardashian, pictured in 2014 and again in 2022, is believed to have had 外科 to augment the size of her butt. She is shown with a much larger one 最初 before showing off her more slimmed 負かす／撃墜する 外見

It was followed by a 割合 of 0.64 with an 普通の／平均（する） 得点する／非難する／２０ of three and 0.68 with an 普通の／平均（する） 得点する／非難する／２０ of 2.9. At the other end of the 規模, 関係者s were least likely to 率 0.58 as their favorite.

For the other 見解（をとる）s, however, 関係者s 階級d the buttocks with a GTI of 0.64 as the most 控訴，上告ing.

の中で gay 関係者s, results showed 関係者s were most likely to 階級 the 割合 of 0.62 as the most 控訴，上告ing.?

研究員s said there was a 重要な difference in 返答s by 地域, with those who lived in southern areas of the US most likely to say they preferred a more voluptuous buttocks on men.

Dr Patel said:?'Our 熟考する／考慮する is one of the first to really 焦点（を合わせる） on what makes the male buttocks most attractive.

'We believe the findings will be helpful in discussions with 患者s considering gluteal enhancement and 供給する 指導／手引 in 達成するing optimal results and 患者 satisfaction.'

利益／興味 in male buttocks enhancements has been rising in 最近の years ― with the numbers coming 今後 rising with the 割合 of all butt alteration 外科s done on men rising from 2.2 パーセント in 1997 compared to 6.2 パーセント in 2012.

This 熟考する／考慮する, also published in the 定期刊行物 of Plastic and Reconstructive 外科 this year, 目的（とする）s to give people a baseline on which butts are most 控訴，上告ing.
