Prepubic Fat in Men: What It Is and How to Reduce It

Prepubic fat is the layer of fat that sits on top of the pubic bone, between the lower belly and the base of the penis. Every man has some, but when it grows it can create a rounded bulge, rub against clothes and make the penis look smaller than it is. This guide explains what the male pubic fat pad is, why it grows, how it affects the way the genitals look, and the realistic ways to reduce it.

The prepubic fat pad is the male version of the mons pubis. For the full background on this area in both sexes, read our guide to mons pubis fat. Our guide to mons pubis fat in men vs women explains why the pad sits differently in each sex.

This guide is general information, not medical advice. If you have pain, swelling, a lump, trouble peeing or sore skin in this area, speak to your GP.

Key Takeaways

• Prepubic fat, also called the suprapubic fat pad, sits over the pubic bone in front of the base of the penis.
• It grows mainly with overall weight gain and shrinks with overall fat loss. No exercise targets it directly.
• A large fat pad can hide part of the penis and make it look shorter, but it does not change its real length.
• In some men it contributes to a buried penis, which can cause hygiene and skin problems and needs a GP review.
• Liposuction and a pubic lift can remove fat that stays at a stable weight, but these are usually private procedures in the UK.

What Is Prepubic Fat?

Where the suprapubic fat pad sits

The suprapubic fat pad is a cushion of fat under the skin, just above the genitals and below the lower belly. It covers the pubic bone and the base of the penis. The names prepubic fat, male pubic fat and suprapubic fat pad all describe the same area. When it is large, people often call it a FUPA, short for fat upper pubic area.

Why everyone has some

A small amount of fat over the pubic bone is normal. It cushions the bone and is present in men of all sizes. What varies is how thick the pad is. Two men at the same weight can have quite different amounts of fat in the pubic area because of their genes.

How it differs from belly fat

Prepubic fat is subcutaneous fat, which means it sits just under the skin. That is different from visceral fat, the deeper fat around the organs that pushes the whole belly forward. Men tend to carry more visceral fat than women, so many men with a fatty pubic area also have a larger waist. Our guide to FUPA in men covers the wider picture.

What Causes a Fatty Pubic Area in Men?

Weight gain

The most common cause is gaining body fat. When you regularly eat more energy than you burn, the extra is stored as fat in many places, including the pubic area. Men who gain weight often notice the fat pad grow at the same time as their waist.

Genes and fat distribution

Genes help decide where your body stores fat. Some men store a lot of fat low on the belly and over the pubic bone, while others carry it higher up. This is why a fat pubic area can show up even in men who are not very overweight.

Hormones and age

Testosterone helps men keep muscle and limit fat storage. Low testosterone is linked with more body fat, and extra body fat can in turn lower testosterone. Muscle also tends to drop with age unless you train, which makes weight gain easier. See our page on FUPA and testosterone for more.

Loose skin after weight loss

After major weight loss, the skin over the pubic area can stretch and sag. This can leave the area looking full even when much of the fat has gone. Diet and exercise cannot tighten loose skin.

Does Pubic Fat Affect Penis Size?

It changes how much is visible

The penis is anchored to the pubic bone, and part of its shaft sits under the suprapubic fat pad. When the fat pad gets thicker, more of the shaft is covered, so the visible length gets shorter. The actual length does not change. Losing fat from the pubic area often makes more of the penis visible again.

Why it can affect confidence

Many men worry about how the area looks, especially in changing rooms or with a partner. These worries are common and understandable. Knowing that the fat pad hides length rather than reducing it can help, and reducing body fat is a practical step that often makes a visible difference.

Prepubic Fat and Buried Penis

What a buried penis is

A buried penis is a condition where the penis is partly or fully hidden under the skin of the pubic area or scrotum. In adults it is most often linked to obesity and a large suprapubic fat pad, and it is more common in men with diabetes. A medical review of buried penis and obesity describes the fat pad as one of the main factors in adults.

Problems it can cause

A buried penis can make it hard to aim when peeing, cause urine to collect on the skin, and lead to soreness, infections such as balanitis and other skin problems. It can also make sex difficult. These are medical issues, not just cosmetic ones. Our full guide to buried penis and pubic fat covers the causes, hygiene and treatment options in more detail.

When to get help

See your GP if you find it hard to keep the area clean, notice dribbling or spraying when you pee, or have red, sore, itchy or tight skin. Your GP may refer you to a urologist. Treatment usually starts with weight loss and good skin care, and some men need surgery.

How to Reduce Prepubic Fat

Lose fat overall with a modest deficit

You cannot choose where fat comes off first, so the main way to reduce male pubic fat is to lose body fat overall. The NHS suggests a steady loss of around 0.5kg to 1kg a week. The free NHS weight loss plan app can help you set a calorie target and track your meals.

Eat for fullness

Build meals around protein, such as eggs, fish, chicken, beans or lentils, plus vegetables and wholegrains for fibre. Cut back on sugary drinks and snacks. Keeping alcohol within the UK guideline of 14 units a week, spread over several days, removes a common source of extra calories for men.

Move more and lift weights

Aim for at least 150 minutes of moderate activity a week, such as brisk walking, cycling or swimming, as the NHS recommends. Add strength training on at least 2 days a week to protect muscle while you lose fat. Our step by step plan on how to lose a FUPA for men includes a weekly routine.

Sleep and stress

Short sleep and long term stress can drive hunger and make it harder to stick to a plan. Regular bedtimes and less screen time late at night are simple places to start.

A realistic timeline

Treatment Options for Male Pubic Fat

Suprapubic liposuction

Liposuction removes fat through small cuts using a thin tube. It suits men with good skin tone whose fat pad stays after they reach a stable weight. It does not tighten loose skin. Our FUPA liposuction guide covers recovery and results.

Pubic lift or suprapubic lipectomy

A pubic lift, also called a monsplasty, removes excess skin and fat and lifts the area. A suprapubic lipectomy cuts out a section of the fat pad. These are often used after major weight loss or as part of buried penis repair. Read more in our guide to monsplasty.

Non surgical treatments

Fat freezing has been studied for male suprapubic fat in small trials, and many UK clinics offer it. Results are usually smaller than surgery and may need more than one session. Our guide to non surgical FUPA removal compares the options.

NHS or private?

Cosmetic surgery is not usually available on the NHS. Treatment for a buried penis that causes medical problems is assessed differently, so speak to your GP about a referral. Otherwise, most men pay privately. Use a surgeon on the GMC specialist register and allow time to think before you book.

Everyday Comfort and Hygiene

Keep the skin clean and dry

Wash the area daily with water or a mild, unperfumed wash and dry it well, including any folds. Moisture trapped under a fat pad can lead to chafing and rashes.

Choose underwear and trousers that fit

Supportive briefs or trunks in breathable fabric help. Trousers with a waistband that sits above or well below the fat pad are usually more comfortable than ones that dig in across it.

Frequently Asked Questions

What is prepubic fat?

Prepubic fat is the pad of fat that sits over the pubic bone, just above the genitals. In men it is also called the suprapubic fat pad or male pubic fat.

Can you lose fat in the pubic area as a man?

Yes, but only as part of overall fat loss. A calorie deficit, regular activity and strength training reduce the fat pad over time, although it is often one of the last areas to change.

Does losing pubic fat make your penis look bigger?

It can make it look longer. The fat pad covers part of the shaft, so reducing it shows more of the penis. The real length does not change.

Are there exercises for the suprapubic fat pad?

No exercise burns fat from one area. Cardio and strength training help you lose fat overall, and core work can improve posture and how the lower belly looks.

Can the NHS remove prepubic fat?

Not usually for cosmetic reasons. The NHS may treat a buried penis or excess skin that causes medical problems. Ask your GP whether you meet local criteria for a referral.

The Bottom Line

Lose fat first, then weigh up treatment

Prepubic fat is a normal pad of fat over the pubic bone that grows with weight gain and can hide part of the penis. Steady fat loss through diet, activity and strength training is the most reliable way to shrink it, and most men see the pubic area change after a few months. If you have hygiene or skin problems, see your GP. If fat or loose skin stays once your weight is stable, liposuction or a pubic lift may help. Our guide to mons pubis fat explains how this area works in more depth.
