Rounding off the year, let’s have a look at penises! We (the societal ‘we’) tend to be a bit more familiar with the constituent parts than we are with vulvas…
Glans: This is the tip or ‘head’ of the penis.
Foreskin: This is a fold of skin that covers the glans of the penis. It can be removed, either at birth or later in life, for either medical or cultural reasons in a process called circumcision. Rates of this practice vary across the world and it isn’t as common in the UK as in other parts of the world.
Urethra: The opening of the penis. Semen, urine and discharge can leave the body here. As with discharge from the vagina, this can be normal. Changes in the discharge (e.g. smell or colour), especially when accompanied by other symptoms (pain, itchiness) can however indicate something’s not quite right and might need checking out.
Shaft: This is the main bit of the penis. Internally are found the tubes that carry urine and semen out of the body, as well as blood vessels supplying the penis – this is part of the mechanism that causes the penis to become hard and bigger during an erection.
The average penis size is 9 cm when not erect, although there is a fairly large and health variation in this.
