1. Follicle Stimulating Hormone (FSH) -
A. production site - anterior pituitary gland
B. target organs - female ovaries and male testes
C. general effects - females (supports the development of follicles in ovaries, which will then produce estrogen. The follicle will get larger as a result of FSH and will release different estrogen types.) Males (used for the formation of sperm).
2. Luteinizing Hormone (LH) -
A. production site - anterior pituitary gland
B. target organs - female ovaries and male testes
C. general effects - females (triggers ovulation and supports the development of the corpus luteum. The corpus lutem will be responsible for releasing progesterone.) Males (stimulates interstitial cells. Considered important in testosterone …show more content…
target organs - seminiferous tubules of the testes
C. general effects - causes sperm development. Also effects secondary sex characteristics such as genitalia, enlargement of the larynx, fat deposition, increase in bone mass and muscle development.
Define the term “puberty”, state which of the above hormones are the first to appear in significant amounts at puberty, and state a typical age of puberty for both females and males. Puberty is defined as the development of secondary sex characteristics, beginning with the increase in production of the gonadotropic releasing hormone. It involves the significant production of sex hormones and the start of menstruation for girls. Gamete production begins during this period. The onset of puberty varies between the ages of 8 and 10 for girls, and 10 and 12 for boys. It usually lasts between 5-6 years for both boys and girls, but girls generally progress more quickly than boys.
Contrast older women and older men in terms of A) changes in the levels of sex hormones, and, B) changes in gamete production.
1. Women -
A. changes in sex hormone levels - drop in progesterone and estrogen occurs around 50 years of age. This decrease in sex hormone levels put older women at a greater risk for osteoporosis and
