Commonly asked questions on Fertility Tests
- We have been trying for a baby since we got married 3 years ago but with no success. What should we do?
- What are the tests to check for infertility?
- Are fertility tests painful?
Have you ever gone through a fertility assessment before?
For those who had done it , you know that it can initially look very complicated with all those internal ultrasound scans, blood tests, X-ray tests and sperm test. For those who have not, rest easy as all those tests are simplified for you.
Fertility test are divided into 2 namely:
- Male (sperm test)
- Female (ultrasound of the ovary & uterus and x-ray of fallopian tubes)
MALE (Sperm) TEST
“A 70 years old man can still reproduce, so this can’t be a major issue right?”. It is a yes-no question. It is true that a man continues to produce sperm but the QUALITY of the sperm deteriorates as he ages. Low sperm quality equals to low chance to conceive.
What is looked for in a sperm test ?
In a well equipped andrology laboratory, there are 4 parameters that are of consent. These parameters are reported according to WHO standards (World Health Organisation).

1) Sperm concentration
The lower range of normality is when at least 15 millions sperms for every millilitre (ml) of semen is found. Sperm concentration above this value is considered “normal”.
This means what’s the percentage of live sperms in the sample. It should be at least 58% ( at least 58 out 100 sperms are alive).
This looked at the movement of the sperm. At least 40% of the sperms should be moving. The movements are further graded according to how fast and direction of the sperm movements.
This looks at how normal a sperm looks. This is done under high powered microscope. At least 4% (you read it correctly!) of the sperms should be normal-looking to be considered “normal”.
Female tests are generally divided into test of ovarian reserve, assessment of the lining of the uterus and a test to look for fallopian tube patency.

1) Ovarian reserve test
This is done by an ultrasound scan during periods to count the total number of ‘resting egg’ (total egg pool or reserve) in both ovaries. Alternatively, a test called AMH (Anti-Mullerian Hormone) can also be done. These test will give an idea of your potential to produce eggs naturally and during an ART treatment.
2) Lining of uterus
This involves an ultrasound scan during mid-cycle (i.e. if you have 28 days cycle, the scan can done about day 12). This is to make sure there is no problem with the lining of the uterus. Embryo implants and grow on the endometrium and a problem with this lining can impair the process of implantation.
3) Fallopian tube test
Fallopian tube carries the egg that are ovulated every month into the uterus. If the tubes are blocked, it affects your chances to conceive naturally. This is when an X-ray test is needed and this test is done just after your period and before you ovulate.
You may need some specialised fertility tests. This depends on your circumstances and your fertility specialist will advise you.
