Male Factor Infertility
Male
factor infertility can be attributed to approximately one-third of infertility
cases.[1] There are many different factors that can cause male factor
infertility. These include: azoospermia (absence of sperm cells), oligospermia
(presence of only a few sperm cells), improper shape, slow motility, or sperm
cells dying prior to reaching the egg. 2
In October of 2013, my husband was
diagnosed with oligospermia and slow motility. When our doctor called to inform
us of our test results, I honestly knew absolutely NOTHING about infertility,
besides the fact that it existed. All of a sudden, our doctor was giving us all
of these medical diagnoses that seemed pretty serious and letting us know that
he was not really sure who we needed to see next for assistance. He informed us
that it would probably be beneficial to see a urologist and that, if he could
not help us, it might be helpful to see a reproductive endocrinologist. Umm…
Who?? I had never even heard of these doctors before!
Our Diagnostic Testing:
But let’s rewind a little to how we
got this diagnosis. At our first appointment, my husband was asked a number of
questions such as, “Have you
ever been hit really hard in the scrotum?”, “Have you ever had surgery
completed in your scrotum area?”, “Have any males on your side been diagnosed
with infertility?”, etc. Then, they informed us
that they would need to obtain a semen sample, which could be collected at home.
Once collected, the sample had to be kept at body temperature and be brought
into the lab within twenty minutes. On a good day, we can make it to the lab
from our house in about forty-five minutes. So instead, we rented a nearby
hotel and practiced driving back and forth to the lab just to make sure that we
would make it in time!
The results took about two to three
days to come in. A few weeks later, another sample was collected and analyzed
and the results were compared. My husband had 4.4 million sperm cells per
milliliter on the first sample and 3.6 million sperm cells per milliliter on
the second sample, which seemed like a lot if you asked me! But, to our
surprise, it actually was not.
So, how many sperm cells are needed in order to become
pregnant?
We soon learned that the average male ejaculates around 100 million sperm
cells per milliliter! Technically, it only takes one sperm to fertilize one egg
in order to achieve pregnancy. However, the process for this to occur is more
grueling than expected. Once a sperm cell is released, it must first make the
journey from the vagina into the fallopian tubes. This journey is very
strenuous and only a few sperm cells are able to survive. For those that do
survive, they must get past the thick layer that encompasses the egg in order
to fertilize. Due to the high number of sperm cells that don’t reach the egg,
men who produce less than 20 million sperm cells per milliliter of semen are at
risk of infertility.3
However, the number of sperm cells isn’t the only thing that matters. In
addition to this, the sperm cell must also be healthy and have adequate
motility and function or it will not be able to make it to or enter into the
egg. 4
What does a
diagnosis of male factor infertility mean?
Thankfully, a diagnosis of male factor infertility does not always have
to stop a couple from being able to conceive a child. Based on your diagnosis
and specific circumstance, your doctor will be able to recommend what the best
route for you and your partner may be.
