Reproductive system
-
male reproductive system
-
-
male sex hormones
-
Follicle stimulating hormone (FSH)- at puberty stitumlates sertoli cells for sperm production and maturation
-
Gonadotropin releasing hormone- released by hypothalamus in the brain to stimulate anterior pituitary gland to release lh and fsh
-
-
-
inhibin- released by the testes when high levels of testosterone are present to release stimulate hypothalamus to release gonadotropin inhibiting hormone to stop production of LH and FSH
-
female hormonal cycles
Ovarian cycle
-
-
-
ovulation
-
triggered by sudden spike increase in LH caused by steady increase in estrogen stimulating the pituitary gland
-
-
Luteal phase
-
when follicle expels the oocyte, the empty shell becomes corpus luteum
corpus luteum secretes progesterone some estrogen, and inhibin which suppresses FSH
in the absence of pregnancy, corpus luteum becomes corpus albicans causing the decrease in progesterone and estrogen
if pregnancy occurs, the corpus luteum continues to secrete progesterone and estrogen
Uterine cycle
-
-
mentration
-
decline of estrogen and progesterone cause the spiral arteries to contract, cells become ischemic and die, and are sloughed off or shed
-
proliferative phase
-
estrogen stimulates growth of blood vessels of the endometrium, causing it to double in thickness
-
secretory phase
-
in response to rising levels of progesterone by the corpus luteum, the uterus becomes ready for pregnancy
