10 Interesting Sperm Facts

[center]1. Sperm Responds to the Food a Man Eats
Several studies reveal that a man’s sperm responds and is
impacted by what he eats. What a man eats daily plays a very
important role in the health of their sperm.
DHA found in Omega-3 essential fatty acid, found in foods like
Alaskan wild salmon and cod liver oil, has been shown to play a
critical role in proper formation of sperm. A study published in
The Journal of Biology and Reproduction, 2011, found that DHA
can improve sperm morphology. A round-headed sperm can become a
healthy, cone shaped head, full of important egg-opening enzymes
once again, when DHA levels are increased. DHA also plays a role
in sperm motility. An increase in DHA levels has shown to play a
role in the fluidity for sperm tail bending and flexing required
for forward movement of sperm.
Another study showed that men who consumed 3 or more cups of
coffee per day had reduced sperm concentration and total sperm
count, as well as lower sperm quality.
Vitamin C has been shown to improve sperm quality and protect
sperm from DNA damage; helping to reduce and chromosomal
problems that could lead to miscarriages. Vitamin C also appears
to keep sperm from clumping together, making them more motile.
Another study, published by Fertility and Sterility, 11/10/2011,
showed that men who ate more whole grain cereals (wheat, barley,
oats) had higher sperm concentration and motility. The same
study showed that consumption of fresh fruit gave sperm a boost
in speed and agility.
2. Men Need to Regularly Climax for Healthy Sperm
Infrequent ejaculation or sexual abstinence can lead to
oxidative stress due to reduction in semen turn-over. This means
that the sperm stay in the gonads longer and therefore are
exposed to reactive oxygen species, leukocytes or other toxic
substances which can damage them. One study showed that men who
ejaculated 4 or more times per month, had better sperm
morphology. That said, if your partner has had a semen analysis
done and has proven to have a low sperm count; your fertility
specialist may suggest to baby dance every other day around
ovulation.
3. Sperm are Susceptible to Damage from Wireless Technology
In 2012, Fertility and Sterility published findings of a study
on the impact of wireless devices such as laptop computers and
mobile phones. Researchers wanted to find out if laptop
computers Wi-Fi connection played a role in decreasing sperm
health alone. In the past it was believed that the heat alone
from a laptop computer may cause adverse effects to sperm
health, but this new study shows that laptop computers connected
to the internet through Wi-Fi damaged sperm through a
non-thermal effect.
Scientists have suggested this may be due to radiofrequency
electromagnetic waves (RF-EMW) as free-radicals. Free-radicals
cause oxidative damage to our cells, including sperm and female
eggs. Free-radical damage may cause sperm immotility, cell death
and lower the integrity of the DNA. It appears men should avoid
holding laptops directly on their laps, and keep cell phones
away from pants’ pockets.
4. Progesterone Gives Sperm Extra Energy to Penetrate the Egg
Considering the size of sperm, they have a great journey to meet
up with the female egg in the fallopian tube. One can imagine
the incredible energy that must be used for this journey. That
is only half the battle for a sperm to create life though. Once
to the egg, also known as the ova, they work to penetrate it.
Whipping their tails frantically seems like it would be very
tiring, but that is where progesterone comes in. Sperm get a
boost of energy from a burst of female progesterone, which
encourages sperm to whip their tails more passionately. This
helps a sperm to penetrate the egg.
Why does the sperm respond to the burst of progesterone? Well,
in 2011 researchers discovered that a protein called catsper
within sperm cells receives the signal from the release of
progesterone. A perfect example of “working together.”
[b]5. Sperm Have a Superhero-Like Power
Sperm can melt the surface of the female egg. They do this by
releasing enzymes from a portion of the head known as the
acrosome, to dissolve the outer membrane of the egg. This helps
the sperm to burrow through the egg wall. The sperm plasma then
fuses with the plasma membrane of the egg. At this time,the
sperm head disconnects from the tail and conception of a new
life occurs.
6. Sperm Have “Body Guards”
Sperm look very different than any other cell in a man’s body.
It is true they are shaped that way to help them get where they
need to go, but they are also shaped that way because they only
carry half as much DNA as other cells in the male body. Because
of this the immune system sees them as a foreign invader.
Specialized cells in the testicles protect sperm cells, creating
a barrier from immune system cells which would otherwise attack
and harm them. It is common for this barrier to be broken and
sperm to be damaged in as many as 70% of all vasectomy patients.

According to a study published in Biology of Reproduction
(1984), sperm can live for up to 5 days inside of a woman, under
the right conditions. More commonly though, sperm live about 2
days, so be realistic in your timing if you are trying to
conceive!
8. Some Like it Hot, Sperm Like it Cold
The testicles are about 7 degrees fahrenheit cooler than the
rest of the body. Healthier sperm need to stay cooler than the
rest of the body. The testicles work much like a refrigerator,
creating a heat exchange from incoming and outgoing blood
vessels.
9. Poor Lifestyle Choices Negatively Impact Sperm Health
Men who smoke cigarettes, drink alcohol, consume caffeine and/or
are obese have lowered fertility due to a negative impact on
sperm health according an influential 2012 Austrian study
published in Reproductive Biology and Endocrinology analyzed the
sperm of 1683 patients undergoing assisted reproductive
technologies (ART).
Men who used nicotine regularly were shown to have poor sperm
morphology and motility. Studies found little difference in how
much nicotine was used daily, just that any use at all had an
increased chance of a negative impact.
Men who drink alcohol regularly also have lower sperm motility
and concentration.
Men with a BMI of 25 or greater were shown to have significantly
more immotile sperm than men with a BMI less than 25. Obese men
also have slower sperm and lower concentration of sperm than
non-obese men.
10. Relatively Quick Turnover: The Lifespan of Sperm
Studies show a range of 42 to 76 days from the time of sperm
production, through maturation, to ejaculation. The good news
about sperm is that they are constantly being produced, unlike
female eggs. This renewal system allows men a great chance to
improve sperm health and count over a few months’ time. While
some sperm are ready-to-go, others are just in the beginning
stages of formation. On top of that, this renewal system lasts
for a lifetime in most men. As a man ages, their sperm health
and count may decline, but it never stops. This is why men can
father children at a much older age than a woman can.[/center]
