reproductive endocrinology I Flashcards
What role does the SRY gene play in sex determination?
triggers development of male characteristics
XX is
XY is
female
male
What structures develop from the Wolffian ducts in males?
epididymis, vas deferens, and seminal vesicles
What structures develop from the Müllerian ducts in females?
fallopian tubes and uterus
How does testosterone influence male reproductive physiology?
promotes development of secondary male characteristics
What is the role of estrogen in female reproductive physiology?
promotes development of secondary female characteristics
What is spermatogenesis?
sperm cell development
Describe the stages of spermatogenesis.
spermatogonia undergo mitosis and meiosis
spermocyte divide into haploid spermatids
spermatids mature into seem cells
What are the main roles of the testes?
produce sperm and secrete hormones
What are the key events of male puberty?
Increased levels of GnRH, LH, and FSH.
Testicular enlargement and initiation of spermatogenesis.
Development of secondary sexual characteristics (e.g., deepening of voice, facial and body hair growth).
Growth spurts and changes in body composition.
What is the role of Sertoli cells
support spermatogenesis
where does spermatogenesis occur
somniferous tubules of testes
What is the primary role of estrogen in the female reproductive system?
prepares endometrium for implantation
What is the primary function of progesterone?
regulates menstral cycle
what happens in follicular phase
FSH simulates follicule growth
