L12 - Sperm Racing Flashcards
SEMEN ANALYSIS
i) what may semen analysis outputs correlate with?
ii) what is the normal range of ejaculate volume?
iii) what may a high and low volume indicate?
iv) how is sperm concentration or density defined? what is a normal value
v) what % live spermatozoa is expected?
i) fertility
ii) 1.5-6ml
iii) low vol = retrograde ejac to bladder
high vol = accessory gland inflammation
iv) conc/density = number of sperm per ml in total ejaculate
v) 58% or more
MOTILITY AND MORPHOLOGY
i) what is it defined as?
ii) what does progressively motile mean?
iii) what is the cut off for lower limit of normal defined by WHO of normal progressive motility?
iv) what does this have poor correlation with?
v) greater than what % of normal morphol sperm is acceptable according to WHO?
i) percentage of progressively motile sperm in the ejaculate
ii) progressively motile means they go somewhere (dont swim in circles)
iii) 32% is lower limit of progressively motile sperm
iv) has poor correlation with ferility
v) greater than 4% is ok
NOMENCLATURE
what are the definitions of
i) normozoospermia
ii) oligozoospermia
iii) asthenozoospermia
iv) teratozoospermia
v) oligoasthenoterato-zoospermia
vi) azoospermia
vii) apsermia
i) normo = normal values
ii) oligo = low conc of sperm
iii) asthen = too little motility
iv) terato = too many abnormals
v) oligoasthenoterato - low conc, low motil and abnormals
vi) azoo = no spermatozoa
vii) aspermia = no ejac
which sperm problem is seen here? why?
i) azoospermia (no sperm production) as no spermatigenetic cells (only sertoli cells)
what cell is lacking here?
lack of leydig cells (surrounding SNT)
what is indicated by A?
developing spermatids and spermatozoa
what structure is shown here?
what cell type is the structure indicated by the arrow lined with?
vas deferens
epithelial cells lining the lumen
what type of cells are shown here? what structure are they lining?
epithelial cells lining the lumen of the vas deferens
