takes sperm how long to mature

Q

sperm should be accessed how long after collection

A

1-2 hours and be kept warm or else will affect motility

-normally placed in 37 degree incubator for 30 minutes to liquify to analyze

16
Q

normal volume of seminal fluid

17
Q

normal pH of fluid

18
Q

if >8 pH

A

infection’ normally with enterobacteria with conversions of nitrate to nitrites

19
Q

if <7 pH will affect

A

motility and production of sperm

20
Q

for looking for motility and forward progression of sperm make

21
Q

men can have low sperm count but got motile=

A

good chance of pregnancy

MOTILITY= HUGE

22
Q

how many fields should be estimated for amount of sperm moving

A

20-25 fields

want to see 50-70% normal motility

23
Q

forward progression

A

are they moving forward
scale of 1-4

24
Q

normal amount of sperm

A

20-120 million /mL

25
how is sperm count
on hemocytometer 1. mix with NaOH with some fluid 2.sit 30 min 3. stops movement of sperm 4. allow to settle before counting
26
how to look at morph for sperm
-spin down liquid so sperm at bottom -put on slide and stain normal sized head with tapering tail 70% need to be normal to be considered "normal"
27
<70% normal looking sperm =
infertility
28
what stain does the sperm viability test use
eosin nigrosin
29
what does the sperm viability test determine
what percentage of sperm are viable/ alive -should coincide with motility
30
colors of sperm viability test
stain will penetrate dead sperm- red live sperm will be- blueish/white look in 25 fields to determine overall
31
what percent of sperm do you want to be alive in the sperm viability test
>50%
32
main sugar sperm uses for energy
fructose
33
we can do a fructose level on
higher % of sperm are dead -measures amount in seminal fluid
34
if you notice a lot of sperm that are together it could be
male producing antibodies against own sperm
35
how to perform sperm aggulating bodies test
draw male serum and add sperm -if see agglutination= antibodies same can be done with female serum
36
what test is done if everything else seems right but you think something is wrong
sperm agglutinating bodies
37
how long does it take post vasectomy to have a sperm count of zero
3 months gold standard= 3 negative sperm counts mean negative
38
tests we can culture for on seminal fluid
* Neisseria Gonorrhea * PCR testing for Chlamydia * PCR for micro plasma hominis * Serology testing for syphilis
