Fertility investigations
Examinations to discover the cause for infertility
are normally started when a couple has unsuccessfully tried to conceive
a child for one year. If there are already known factors affecting
fertility the treatment can be started earlier (these causes include
surgical operations on the fallopian tubes, ovaries or the uterus,
irregular menstruation, male testicular diseases etc). In order
to diagnose the cause for infertility, we aim to address three main
questions:
|
1) Does the maturation of the egg and ovulation occur in
a normal way?
2) Is the anatomy of the female reproductive organs normal,
that is, are the uterus and the fallopian tubes functionally
healthy?
3) Is there sufficient number of mobile sperm cells for fertilization?
A) Female infertility

Does the maturation of the egg
and ovulation occur in a normal way?
If the woman has a regular period of 25-35 days
it is most likely that the maturation of the egg and ovulation are
normal. An ultrasound scan will confirm a normal growth of the follicle.
You can also estimate the time of ovulation with urine tests at
home (the LH test). If needed, blood tests are done to confirm that
ovulation occurs (serum progesterone one week after ovulation).
Is the anatomy of the female reproductive organs normal,
that is, are the uterus and the fallopian tubes healthy?
Tubal patency used to be confirmed by laparoscopy
or hysterosalpingography (radiological examination with contrast
medium). These methods can still be used in certain special cases,
but normally the first examination entails an ultrasound scan combined
with hydrosonography or salpingosonography (SSG). If the fallopian
tubes are blocked the treatment of choise is in vitro fertilization
(IVF). The most common causes for damaged fallopian tubes are infectious
diseases (for example chlamydia), endometriosis, ectopic pregnancy
and surgical operations on the ovaries and the fallopian tubes.
B) Male Infertility
Is there sufficient number of mobile sperm cells for fertilization?
Male fertility may be examined with a microscopic examination of
the sperm where special attention is paid to the quantity and the
motility of the sperm cells. Based on this examination it is possible
to give an evaluation concerning the fertility of the man. The quality
of the semen may vary considerably over time. A reduced sperm count
and lower mobility of the sperm cells may be due to infectious diseases
(such as chlamydia or the mumps), a testicular injury, certain medication,
use of anabolic steroids and dissolvents, or smoking, but often
the cause remains unclear. In addition, hereditary causes are a
possible reason for a low sperm count or poor motility of the sperm.
