When a couple is considered subfertile?
A couple is considered subfertile
when despite the effort for achievement of a pregnancy,
this is not rendered possible after at least of one
year unprotected intercourse. It is of great
importance of course for the couple not to use
contraceptive methods, and to live in place where the
conditions are comfortable for intercourse.
What it is the frequency of
subfertile couples in the general population?
It is calculated that in western
countries 10 with 15% of couples cannot acquire a child
without the help of science.
What is the percentage of
contribution of men's of factor in a subfertile pair?
Roughly 20% of cases of subfertility
are solely attributed to a male factor. In the 30 to 40%
of cases the feminine and male factor are considered to
be equally involved, rising thus the male factor to the
total percentage of 50%.
What are the causes of male subfertility?
The causes can be many, but they can be separated in
three categories.
a. The testicular dysfunction, which can be attributed
to a toxic factor (fever in childhood, drugs etc), or to
a Varicocele.
b. The post testicular causes, such as Chronic
Prostatitis, and the anatomic obstructions of spermatic
ducts.
c. The endocrine causes that are relatively infrequent.
What it is the most frequent treatable cause of male
subfertility?
In the daily medical practice, we can say that
Varicocele and Chronic Prostatitis are the most frequent
and treatable causes of male subfertility.
What is Varicocele?
Varicocele is the enlargement of
veins of testicle especially on the left side, resulting
in testicular dysfunction, and production of sperm of
poor quality. The treatment Varicocele is the surgical,
with a small surgical incision in lower abdomen the
internal spermatic vain is ligated and the testicular
function is restored in the majority of cases
 .
What it is the more
important examination for the investigation of male
subfertility?
Without doubt spermodiagramm is
the fundamental examination for the diagnosis of male
subfertility.
However it should always be combined with a proper
physical examination, and patient’s history taking.
What are the usual forms of sperm
dysfunction?
Oligospermia (where the number of
sperms is smaller than usual), Asthenospermia (where is
observed reduction of mobility of sperms), and finally
Azoospermia (absence of spermatozoa from the semen).
When a man is considered subfertile?
There is not a cut off value in
spermodiagramm parameters what can separate the men in
fertile or not. Apart from the absolutely physiologic or
pathological cases, the majority of the patients it is
found between this two limits and in order to appreciate
the degree of subfertility the caring urologist should
consider and other factors as well.
Are there any treatment options
fro male subfertility?
Thankfully there are many treatments
for male infertility. The surgical treatment of
Varicocele offers a substantial possibility of quality
of sperm improvement, but even those that do not respond
to this method of treatment, they can relay on the
methods of assisted reproduction.
