Reproductive Physiology Flashcards
where is sperm produced
in the testes in the seminiferous tubules, takes 75 days
where is testosterone produced
leydig cells produce testosterone in the testicles
what are the target organs of testosterone
skin-har growth liver- synthesis of proteins brain-libido muscle- strength bone marrow- stem cells bone- close of epiphysis sex organs- penile growth, prostate
what is the process of spermatogensis
3 phases- spermatocyogensis
meiosis
spermiogenesis
what is the function of the ovary
to produce eggs and hormones
egg develops in uterus every month under hormonal control
what controls the menstural cycle
hypothalamus releases GnRH
stimulates LH and FSH to act on the ovaries
what is the role of GnRH
to be released from hypothalamus to stimulate LH and FSH from anterior pituitary
what is the role of Lh
maintain dominant follicle, induce follicular maturation and ovulation
what is the role of FSH
to stimulate follicular recruitment
where is oestrogen produced and what is its role
produced from granulosa
cells
stimulates proliferative endometrium
where is progesterone produced and function
maintains secretory endometrium
produced in corpus letup
what is oogenesis
differentiation of ovum into a cell component which can then be fertilised
what is menses
when the corpus luteum is broking down and the endometrial lining Is shed- in the first 7 days
what is the proliferative phase
7-14 days estorgen is released to thicken lining, release mucus and initiates Fallopian tube formation
what is the secretory phase
12-28 days progesterone furthers more thickening
