While a woman is born with all
eggs she'll ever have, men produce sperm on a continual basis. Therefore, what a man does on a daily basis can affect
sperm maturation process.Smoking, drinking, drugs, stress, poor nutrition and lack of exercise all can contribute to poor sperm quality. And, it was recently discovered, a man's sperm quality begins to decline around
age of 25.
There are five main factors that contribute to overall sperm quality. They include sperm motility, speed, count, concentration and morphology (shape and size).
A weakness in any of these areas can affect
chances of conception.
Motility
Sperm motility is a term that describes sperm's ability to move in an active fashion: in other words, are
sperm "strong swimmers?" In healthy sperm, typically more than 50% are active with over 25% moving forcefully in one direction. Motility enables
sperm to travel through
cervical canal, into
uterus and
fallopian tubes and, finally, to penetrate
egg.
Speed
The forward movement of sperm called progressive motility, forward progression or rapid linear progression. There are also several different ways to classify forward movement.
According to
World Health Organization (1999), in a healthy male, greater than 25% of sperm will exhibit progressive motility. It is thought that these are
sperm with
best chance of successfully fertilizing an egg.
Rapid linear progression showed a greater than 60 % improvement after four months of treatment with acupuncture, herbal medicine and supplements.
Sperm Count
Sperm count refers to
number of sperm in
fluid that is ejaculated (semen). There are over 40 million sperm in a normal ejaculate. A total count below 40 million may indicate decreased fertility. With
Berkley Center's unique protocol of acupuncture, herbal medicine and supplements, count increased more than 14 % after four months of treatment.
Concentration
Concentration is a measure of
number of sperm cells in a milliliter of semen. Normal concentration is at least 20 million sperm cells per milliliter of semen. With
Berkley Center's unique protocol combining acupuncture, herbal medicine and
appropriate supplements, concentration improved after four months of treatment.
Morphology (shape and size)
A healthy sperm cell will have a shape similar to a tadpole. The sperm's oval head contains
genetic material,
center provides energy and
tail propels
sperm forward.
Using
strict criteria put forth by
World Health Organization (1999), studies of Assisted Reproductive Technology programs show lower pregnancy rates with less than 15% normal forms. Furthermore, experts believe that abnormally shaped sperm cannot fertilize an egg.
Subfertility
The term, subfertility, refers to couples that are unable to achieve conception after a year of unprotected intercourse (or 6 months if
woman is over age 35). It is different from infertility. A subfertile couple merely has lower odds of conceiving during any given month than fertile couples.
Statistics at a glance
*Human reproduction is surprisingly inefficient and quite complex --
likelihood of pregnancy within any given month is believed to be only 25 percent among fertile couples.
