Answer:
Dear
Sadiq,
The force
and amount of semen that will be ejected during an ejaculation will
vary widely between men and may contain between 0.1 and 10 milliliters.
Adult
semen volume is affected by the time that has passed since the previous
ejaculation; larger semen volumes are seen with greater durations
of abstinence.
The number
of sperm in an ejaculation also varies widely, depending on many factors,
including the time since the last ejaculation, age, stress levels,
and testosterone.
Greater
lengths of sexual stimulation immediately preceding ejaculation can
result in higher concentrations of sperm.
An unusually
low sperm count, not the same as low semen volume, is known as oligospermia,
and the absence of any sperm from the semen is termed azoospermia.
Oligospermia
(originally oligozoospermia) refers to semen with a low concentration
of sperm ('sperm count')
A low
sperm count would be defined as less than 20 million sperm per ml
of semen.
On average,
sperm count should be above 60 million/ml.
According
to the National Institutes of Health, a "good" sperm count
is characterized by several factors.
The amount
of sperm per volume of semen is very important for fertility. On average,
each ejaculation should produce 1.5 to 5.0 milliliters of semen.
The average
sperm count is 20 to 150 million per milliliter of semen.
The shape
and motility of the sperm can also affect male fertility. In order
for a sperm count to be considered normal, at least 60 percent of
the sperm should be normally shaped and able to swim forward.
