a fact or a myth.
FACT O R M Y T H ?
Hormones such as testosterone, helps the
germ cells divide and change several
times and gradually turn into spermatids
or young sperm cells.
FACT O R M Y T H ?
Testosterone is the male hormone, so it ’s
only for male.
FACT O R M Y T H ?
Estrogen is the only hormone I need to
worry about menopause.
FACT O R M Y T H ?
Estrogen is the only hormone I need to
worry about menopause.
FACT O R M Y T H ?
Without estrogen, females are at risk for
weak bones later in life
FACT O R M Y T H ?
Progesterone is less important than
estrogen which is the “Queen” hormone.
HORMONES
chemicals that coordinate different functions in your body
by carrying messages through your blood to your organs,
skin, muscles and other tissues.
HYPOTHALAMUS
The seat of emotion. Regulator / regulator of the pituitary gland.
It will signal the anterior pituitary gland to release or inhibit the
secretion of reproductive stimulating hormone by releasing
GnRH (Gonadotropin Releasing Hormone).
PITUITARY GLAND
For reproductive system it releases (FSH) Follicle Stimulating
Hormone and (LH) Luteinizing Hormone that play important
roles in the production of sperm and egg, so as the release of sex
hormones.
Pituitary Hormone Functions
Follicle-stimulating hormone Stimulates egg maturation in the ovary and release of sex hormones.
Lutenizing hormone Stimulates maturation of egg and of the corpus luteum surrounding the
egg, which affects female sex hormones and the menstrual cycle.
Thyroid-stimulating hormone Stimulates the thyroid to release thyroxine.
Adrenocorticotropic hormone Causes the adrenal gland to release cortisol.
Melanocyte-stimulating hormone Stimulates synthesis of skin pigments.
Growth hormone Stimulates growth during infancy and puberty.
Antidiuretic hormone Stimulates the kidney to conserve more water.
Oxytocin Affects childbirth, lactation, and some behaviors.
