Failure to mature sexually = Estrogen deficiency in young females Sterility = Deficiency of estrogen in adults Development of fibroids in uterus = Over secretion of estrogen Polycystic ovaries = Over secretion of estrogen
Explain the role of estrogen in the development of secondary sex characteristics in females.
Estrogen is responsible for the development of secondary sex characteristics in females such as breast development and widening of the hips.
What are the consequences of estrogen deficiency in young females?
Estrogen deficiency in young females can lead to failure to mature sexually and sterility.
Describe the effects of over secretion of estrogen.
Over secretion of estrogen can lead to the development of fibroids (abnormal growth) in the uterus and polycystic ovaries.
What is the source of estrogen and what stimulates its secretion?

What is the role of progesterone during pregnancy?
Progesterone is produced and released from placenta during pregnancy, and it causes further thickening and vascularisation of the uterus wall for maintaining the state of pregnancy.
What is the effect of under secretion of progesterone during menstrual cycle?
Under secretion of progesterone during menstrual cycle decreases the chance of pregnancy and may cause early menstruation.
What is the consequence of under secretion of progesterone during pregnancy?
Under secretion of progesterone during pregnancy may lead to miscarriage.
What are the functions of the male gonads?
The male gonads, testes, produce sperm and male sex hormones called testosterone.
What is the role of testosterone during puberty?
During puberty, testosterone initiates the maturation of the male reproductive organs, the appearance of secondary sex characteristics, and sex drive.
What are the effects of under secretion of testosterone?
Under secretion of testosterone causes the development of feminine characteristics and male sterility.
What is the source of testosterone?
Testosterone is secreted from interstitial cells among seminiferous tubules in the testes.
What is the function of testosterone in adult males?
Testosterone is necessary for normal sperm production and maintains the reproductive organs in their mature functional state in adult males.
What are the consequences of under secretion of testosterone?
Under secretion of testosterone causes the development of feminine characteristics and male sterility.
