reproduction and development Flashcards
SRY gen
causes male development
female reproductive precursor organs
ovary and mullerian duct
male reproductive precursor organs
testes and wolffian duct
anti mullerian hormone
released by prenatal testes, defeminizing effect
androgens
released by prenatal testes, masculating effect, testosterone converted by 5a-reductase into DHT
androgen insensitivity syndrome
XY without androgen receptor, no internal sex organs, external female
persistent mullerian duct syndrome
XY with no anti mullerian hormone present or working receptor, no defeminization
what does the adrenal cortex produce
cholesterol
progesterone
only in females, in males as an intermediate, causes formation of endometrium
oestrogens
mainly in females
androgens
mainly in males, mostly intermediate in females
aromatase
in females, turns testosterone into oestradiol
GnRH
stimulates release of LH and FSH
tubuli seminiferi
sperm producing cells, more activated by FSH
interstitial cells of Leydwig
synthesis of testosterone, stimulated by LH
sertoli cells
development of sperm, synthesis of testosterone binding protein and inhibin
oestrogens
produced in the ovary and adrenal cortex, causes secondary female characteristics to develop
oocytes
develop into follicles
follicular phase
high oestrogen levels, FSH and LH go up
luteal phase
progesterone and medium oestrogen, LH goes down
AMH
prevent more follicles from developing every cycle
