The human penis comes in all shapes and sizes, but one thing most have in common is a mushroom-shaped tip, scientifically known as the glans. The current theory is that the shape of the penis tip is meant to scoop out the semen of previous male partners, thus increasing the chances of impregnating a woman who has had sex with multiple partners in a short period of time. This theory, known as the semen displacement theory, has been tested by scientists with compelling results. Other factors, such as thrusting depth and power, and penis length, also play a role in semen displacement. Circumcision may also affect the prominence of the mushroom shape, as the glans of circumcised penises are typically visible at all times.

The shape may help to scoop out other men's semen
The human penis comes in all shapes and sizes, but most have a mushroom-like tip, known as the glans. The shape of the glans is influenced by various factors, including circumcision and hormones like testosterone and dihydrotestosterone.
One theory, known as the semen displacement theory, suggests that the mushroom shape of the penis evolved as an adaptation to female infidelity. According to this theory, the ridge created by the flared glans acts as a tool to scoop out the semen of previous male partners during intercourse, increasing the chances of the new partner impregnating the woman. This theory is supported by a 2003 study from the State University of New York, which found that penises with a more pronounced mushroom shape were more effective at displacing semen.
Additionally, circumcision may play a role in semen displacement. Circumcised penises tend to have a more accentuated mushroom shape, and due to reduced sensitivity, circumcised men may engage in deeper and more vigorous thrusting, which is more likely to displace semen. However, not all experts agree with this theory, arguing that there are likely other evolutionary factors at play and that the semen displacement ability could be merely an added benefit of the shape rather than the cause of its evolution.
The mushroom shape of the penis also has implications for sexual stimulation and pleasure. The increased surface area and friction created by the flared glans enhance sensation for both partners during intercourse. Therefore, the shape of the penis tip serves multiple functions, including possible reproductive advantages and increased sexual pleasure.

Circumcision may make the mushroom shape more noticeable
The penis tip is typically shaped like a mushroom, with the glans flaring out from the shaft to create a distinct ridge and rounded tip. This shape is known as the corona, and it is packed with nerve endings, making the penis head very sensitive to touch, which is essential for sexual arousal and pleasure.
While circumcision does not change the underlying shape of the penis head, it can affect how exposed the glans are. In uncircumcised men, the foreskin usually covers the head when the penis is flaccid, making the mushroom shape less noticeable. In contrast, circumcised individuals have their glans exposed at all times, making the mushroom shape more prominent.
Additionally, circumcision can slightly influence sensitivity due to skin removal, resulting in reduced sensitivity in the penis head. According to Gallup, this may lead to deeper and more vigorous thrusting during intercourse, which is more effective at displacing a previous partner's semen. This theory, known as the semen displacement hypothesis, posits that the mushroom shape of the penis head evolved as an adaptation to female infidelity, increasing the chances of impregnating a woman who has had multiple partners in a short period.
In a 2004 study, Gallup found that one in four women had sex with two or more males within a 24-hour period, supporting the idea that female infidelity was common throughout human evolution. Furthermore, a 2016 study by Shackelford showed that husbands whose wives spent more time with male friends exhibited more semen-displacing behaviours during sex, such as thrusting harder.
While not everyone agrees with Gallup's theory, the accentuated mushroom shape of circumcised penises and the associated reduction in sensitivity may contribute to more effective semen displacement.

The shape creates more friction during thrusting, enhancing sensation
The human penis comes in all shapes and sizes, from the pencil to the sausage and cone shape. However, one thing that most penises have in common is a toadstool-like head, or a "mushroom shape". This shape is caused by the corona – the flared ridge where the shaft meets the head.
The mushroom shape of the penis may not just be about how it looks but may also serve a purpose during sex. The flared edge creates more friction during thrusting, which can enhance sensation and stimulation for both partners. The increased surface area of the head of the penis allows for more friction for both the male and the female, increasing stimulation, and helping trigger climax.
The shape of the penis head is also thought to act as a sort of "'plug-and-suck', pushing out semen out of the woman's vagina. This is known as the "semen displacement theory". The idea is that, in order for men to ensure they carry on their lineage and impregnate a woman, their penis acts as a "'tool' to scoop out the semen of love rivals from the vagina. As the semen from another male is removed, it is replaced with that of the new partner, increasing the chances of him becoming a father if the woman has had sex with multiple people in a short amount of time.
According to evolutionary psychologist Gordon Gallup, the mushroom shape of the penis evolved as an adaptation to female infidelity. The shape may have developed to help remove semen left by previous partners during intercourse, giving a new guy a better chance of getting a woman pregnant. However, not everybody in the world of urology agrees with Gallup's theory. Some experts argue that there are many other factors at play during sex, and that there could be another evolutionary cause for the shape.

The tip is pinkish/purple due to vasodilation of capillaries during erection
The colour of the tip of the penis during an erection is due to vasodilation of capillaries. This is a normal physiological response.
The glans penis naturally flares out from the shaft, creating a distinct ridge and rounded tip. This shape is called the corona, and it is responsible for the mushroom-like appearance of the penis. The urethral opening is located at the centre of the glans, where urine and semen exit the body. This area is packed with nerve endings, making the head of the penis highly sensitive to touch, enhancing sexual arousal and pleasure.
The mushroom-like shape of the penis head, or glans, is believed to have evolved for several possible reasons. One prominent theory, known as the semen displacement hypothesis, suggests that the shape helps to remove semen left by previous partners during intercourse. The coronal ridge creates more friction during thrusting, enhancing sensation for both partners, and may also facilitate the displacement of rival semen.
According to evolutionary psychologist Gordon Gallup, the mushroom shape of the penis allows men to "scoop out" or displace another male's semen, increasing the chances of impregnating a woman who has had multiple partners in a short period. Circumcision may also play a role in semen displacement. Gallup notes that circumcised penises have a more accentuated mushroom shape and reduced sensitivity, leading to deeper and more vigorous thrusting, which is more effective at displacing semen.
While the semen displacement hypothesis has been supported by laboratory experiments using latex penises and artificial vaginas, not all experts agree with this theory. Some believe that there may be other evolutionary causes for the penis's shape, and semen displacement could be an additional benefit. Other factors, such as women's preferences for penis size, hormones, and sexual pleasure, may also have influenced the evolution of the penis's shape.

There is no standard penis shape, and all variations are normal
While penises typically have a mushroom-like shape at the tip, there is no standard penis shape, and all variations are normal. Size, girth, angle, and circumcision are some of the factors that contribute to the diversity of penis shapes, which include pencil, sausage, and cone shapes.
The distinct shape of the penis tip, known as the glans, is due to the corona, a flared ridge where the shaft meets the head. This shape creates a distinct outline and enhances sensation during sex by increasing friction for both partners.
The evolutionary theory behind the mushroom-shaped penis tip suggests that it may have developed as a result of female infidelity. According to this theory, the shape is advantageous for scooping out the semen of previous male partners, increasing the chances of successful impregnation. However, not all experts agree with this theory, and some believe that other factors may have primarily driven the evolutionary development of this shape.
It is important to remember that variation in penis shape is natural and unique to each individual. Unless there are concerns about pain, sudden changes, or functional difficulties, differences in shape do not indicate any cause for alarm.
