Female Reproductive Flashcards
(47 cards)
Where is GnRH produced?
Hypothalamus
GnRH stimulates production of
FSH
LH
What does the FSH do in the male?
Stimulates spermatogenesis (PRODUCTION OF SPERM)
What does FSH do in female?
Stimulates development of follicle (egg)
What does LH do in the male?
Secretes testosterone by the interstitial cells
What does LH do in the female?
LH surge leads to ovulation
Functions of testosterone
Stimulates spermatogenesis
Affects sexual drive (libido)
Stimulate metabolism
Stimulate male secondary sexual characteristics
Maintains accessory glands and organs of male reproductive tract
Function of progesterone
Stimulate endometrial (THIS IS A LAYER OF UTERUS) growth and secretion
Functions of estrogen
Stimulating bone and muscle growth
Stimulates female secondary sexual characteristics
Initiating repair and growth of endometrium
What are the principle organs of the female reproductive system?
Ovaries (gonads, and there’s 2 of them)
Uterine tubes
Uterus
Vagina
Where do blood vessels enter the ovary
At ovarian hilus
What covers the ovary
Tunica albuginea
What ligaments hold the ovaries
Ovarian and suspensions ligaments
Oogenesis
Egg/ ovum production
Produces haploid gametes by means of meiosis
How often does oogenesis occur
Monthly in ovarian follicles
Phases of ovarian cycle
Follicular phase (preovulatory)
Luteal phase
Post ovulatory
Follicular phase
Increase size of follicle
Occurs before ovulation
Days 1-14
Includes pre-ovulatory phase
Most variable part of cycle
FSH stimulates follicles to grow and secrete estradiol
Luteal phase
Occurs after ovulation
What are the steps in the ovarian cycle
- Formation of primary, secondary, and tertiary follicles
- Ovulation
- Formation and degeneration of the corpus luteum
Corpus luteum begins to degenerate 12 days after ovulation if there is no fertilization (THIS PART WILL SHED)
- Degrading of corpus luteum
How long is a normal cycle?
28 days
+/- 7 days
First day of menstration = first day of cycle
How many eggs are female born with
2 million eggs
Ovulation
Rupture of mature follicle and release of the ovum
Happens day 14
Estradiol stimulates a surge of LH and a smaller amount of FSH
LH stimulates primary oocyte completes meiosis I (MAKES SECONDARY OOCYTE)
What are the parts of the uterine tubes
Infundibulum
Ampulla
Isthmus
What are the other names for uterine tubes
Fallopian tubes
Oviductss
