THE STAGE OF PUBERTY
It is the process of physical changes by which a child's body becomes an adult body capable of reproduction
WHEN DOES PUBERTY START?
Puberty usually starts between the ages of 8 to 13 for girls and 10 to 15 for boys.
It is initiated by hormone signals from the brain to the gonads (ovaries and testes)
In response, the gonads produce a variety of hormones that stimulate the growth, function, or transformation of brain, bones, muscle, blood, skin, hair, breasts, and reproductive organs https://en.wikipedia.org/wiki/Puberty

PHYSIOLOGICAL CHANGES
PARTS OF THE REPRODUCTIVE ORGANS AND ITS FUNCTIONS
MALE FEMALE
Bladder – where urine is stored
Testicles – the 2 testicles produces sperm cells and the male hormone testosterone
Scrotum – holds the “testicles” or “testes” at the proper temperature – lower than 98.6 degrees – for making sperm
Epididymis – where sperm are stored and transported through the vas deferens
Vas Deferens – A tube that transports a sperm from epididymis through the urethra
Seminal Vesicle – two long skinny glands which contribute sugars to help nourish the sperm on their long journey
Prostate Gland – the fluid from which is a lubricating liquid, allowing the sperm to swim free Urethra – tube that carries semen and urine out of the
penis
Penis – Delivers sperm from the urethra into the female reproductive tract
Ovaries – ovaries produces egg cells and hormones like estrogen and progesterone
Fallopian Tubes – where an egg cell will pass through once it is released from an ovary Uterus – is also known as the womb. This is where a
baby will stay as it develops into its full term
Cervix – the cervix is the lower portion of the uterus.
This expands up to 10 cm once a mother is about to give birth
Vagina – is a tube that connects the uterus to the external part of the body. This is where a baby will pass during birth

BOYS
Wet dreams occur naturally in boys and happen when there is excess semen in the body. Semen is released through ejaculation
Boys should undergo circumcision which is a minor operation where the skin covering the tips of the penis (foreskin) is removed.
This is done to prevent accumulation of dirt in that area which can cause irritation or infection
Boys get circumcised by the age of 12-14 in a hospital or clinic.
