Semen Analysis
Male sub fertility is present in up to
47% of infertile couples; therefore, the semen analysis is
critically important. There are often multiple causes of infertility
and no treatment of the female will be successful in the absence of
sperm that can reach and fertilize the egg.
The male fertility evaluation should be
performed by a reproductive laboratory that has personnel with
extensive andrology experience. Many different semen parameters are
evaluated including:
-
Number of live sperm. Normal = > 20
million per milliliter
-
Volume of fluid in the ejaculate.
-
Motility (ability to move or swim in
a straight line). Normal = > 50%
-
Shape and size of the sperm. Normal =
>14% "highly normal forms" ( using strict criteria)
-
Presence of white blood cells which
may indicate an infection. Normal= < 5 white blood cells per
microscopic field.
-
Intrauterine insemination is often
used to treat mild male factor infertility. Moderate to severe
male infertility requires IVF with ICSI or the use of a sperm
donor.
Treatment mild of male factor
infertility usually consists of
intrauterine
insemination. In more severe cases, donor sperm can be used
or IVF with
intracytoplasmic injection is employed. Today's ICSI
technology combined with surgical techniques, such as
TESA can
produce pregnancy when a single sperm can be obtained.
