Puberty and girls
The female body produces the hormones progesterone and oestrogen, which start the changes of puberty. Sexual development can start for most girls, anywhere between the ages of 8–14.
The changes a girl goes through during puberty
• Breasts grow.
• Nipples become larger and fuller and they may become darker in colour.
• Face shape changes and becomes less childlike.
• Voice becomes slightly deeper, although not as noticeable as with boys.
• Body shape changes as hips widen.
• Growth spurt which includes lengthening of arms and legs.
• Weight gain.
• Hands and feet grow bigger.
• Hair grows under arms and on legs.
• Hair on arms and legs may become darker.
• Pubic hair grows on vulva.
• Vagina discharges a clear or slightly milky discharge – this is normal and helps to
keep the vagina healthy.
• Ovaries release an egg which, if not fertilised by sperm, is broken down and shed
with the lining of the womb. (This is known as menstruation or a period.)
• Hormonal changes can lead to girls’ mood swings including irritability, tearfulness,
overwhelming happiness and confusion.
• May feel intense emotions of love, low self-esteem, frustration and apathy.
• They may become argumentative and bad tempered, and challenge authority.
• May be physically attracted to others (male or female).
• Begin to want more independence from parents.
