Just a quick drive-by post...
Steal - Here are some SA metrics:
Normal results for semen analysis: (From random site on the web)
-Semen volume: 1.0–6.5 milliliters (mL) per ejaculation.
-Sperm count: 20–150 million sperm per milliliter (mL).
*However the total count should be higher than 40 millions/ml.
-Morphology:At least 70% of the sperm have normal shape and structure.
-At least 60% of the sperm show normal forward movement.
**It is advisable to avoid sexual activity 2 to 5 days before semen analysis is done to ensure that sperm count will be highest.
Another random site:
Volume: 1.5-5.0 ml
Sperm: 20 million per ml
Motility: Over 60%
Morphology >14
Another random site:
Concentration should be >48 million
Motility should be >63%
Morphology should be > 12
* That being said, most docs consider < 5 for morphology to be infertile, so there is definitely some wiggle room.
From the University of Iowa:
Volume > 2 million
Motile Sperm/ejaculate: >20 million
% Motility: >50%
Morphology: >11
From the New England Journal of Medicine article on Sperm and infertility:
Fertile Range: >48 concentration, >63% motility, and >12% morphology
Indeterminate Range: 13.5-48 concentration, 32-63% motility, and 9-12% morphology
Subfertile Range: <13.5 concentration, <32% motility, and <9% morphology
An excerpt from the an Oxford Medical Journal article:
"...The pregnancy rate under in-vivo conditions was significantly higher when seman samples had a better sperm morpphology, with significant differences for thresholds at 4, 7, and 14% of strictly normal forms."
I would add that these are really broad. In my research I have found that there is a good deal of debate about what is considered "fertile".
You also need to consider that the combination of factors, ie if volume is really high, they might worry less about morphology.
I hope that helps!
