reproductive system Flashcards
Process if sperm production is
Spermatogenesis
The female gamete is the ______ the male gamete is the _____
oocyte, sperm
The sex steroids, estorgen in femal and androgens in males, stop their own production by negative feedback on the:
Pituitary gland and the hypothalamus
The hypothalamus releases gonadotrophin releasing hormones (GnRH) which stimulates the release of ______ and _______ from anterior pituitary gland cells
Luteinizing hormone (LH), follicle-stimulating hormone (FSH)
In the testis, which type of cell produces testosterone
Leydig cells
The signal for ovulation involves communication between the following four structures. Which list has these structures in the correct order
Hypothalamus, pituitary gland, ovary, follicle
Five adverse effects of taking an anabolic androgenic steroid (AAS), if you are male are:
Liver, testicular aptrophy, HBpressure, hair lose, infertility
which drug has these side effects in female: acne, premature baldness, high blood pressure, altered mood and menstrual irregularities
anabolic steroide
poly cystic ovarian syndrome is associated with high levels of
testosterone
which hormone is produced in the testes
testosterone
which hormones causes FSH and LH to be released
GnRH
which side effect from steroid use can happen in females
premature male pattern balding
which of the following substances would most likely be used by an archer
beta-blockers
what are the three phases of menstrual cycle
- secretory phase
- proliferative phase
- menstrual phase
the source of FSH in the body is
anterior pituary gland
what hormones is/are needed for sperm production
testosterone and FSH
in both males and femles, anabolic steroids can cause low blood pressure, no heart attacks or less chance of stroke
T/f
false
t/f FSH and LH released from posterior pituitary
false
where does spermatogenesis occur
semiferous tubules
after conception, where does the embryo/fetus develop
uterus
what cells secrete testosterone
leydig cells
anabolic- androgenic steroids (AAS) mimic which naturally occurring hormone of the body
testosterone
anabolic-androgenic steroids can shut down HPG axis in both males and females as it can supercharge the negative feedback
T/F
true
what is the pathway of sperm
seminiferous tubules, epididymis, vas deferens, ejaculatory duct, urethra
what is percieved benefit of anabolic steroids
increased speed of recovery
what does it mean to have exercise - induced amenorrhea and oligomenorrhea
missing periods
- no LH surge
- No estrogen/ no progestone
- failure of hypothalamus - pituitary -gonad axis
if someone as absence of menarche by 15yrs and absence of menstruation for >3months what is this
amenorrhea
is someone has 9 or less periods in 12 months what is this
oligomenorrhea
if someone has gone through 12 consecutive months w/o menstrual period what would this be
