Understanding your fertility test results is another significant aspect of the fertility journey. In our clinic, we have a very comprehensive fertility testing protocol that we use with patients participating in the Fertility BreakthroughTM program. There are at least 50 parameters or tests that may need to be performed for a couple experiencing fertility problems, in order to rule out possible reasons or causes of infertility.


Having tests done is important, but so is the quality of the actual testing. So ehere to go for fertility tests? We highly recommend going to a specialist fertility laboratory, as opposed to a general one. The former offers a much higher and advanced testing that will give you a better understanding of where your fertility is at. In this article, we are going to talk about the essential tests in gauging fertility — emphasizing four fertility tests for both partners. If we can only request for some tests, we will absolutely make sure to order them.

Thyroid function test and thyroid antibodies

Who to take: Females


When to take: Any time in the cycle


What is it for: Proper thyroid function is vital for ensuring the mother’s and the developing embryo’s metabolism both work effectively. The risks of miscarriage and developmental complications in the fetus are likely to be increased by strain on the hypothalamus-pituitary- thyroid axis (often present in cases of female infertility). 


Similarly, permanent thyroid damage can occur as a result of thyroid antibodies. If this is happening, it is important to find out and use other methods necessary to ensure the thyroid does not become the reason for infertility — and even recurrent spontaneous abortions.[1-5]

Vaginal swab and culture

Who to take: Females


When to take: Any time in the cycle


What is it for: There are infections to be ruled out, which can negatively impact a couple’s ability to conceive and a woman’s ability to keep a healthy pregnancy to term. These can also affect pregnancy in its very early stages. 


In addition, many of the sexually transmitted infections pose a very real concern to a developing pregnancy and embryo. It is recommended that a woman has a high vaginal swab performed by her general practitioner (GP) or specialist, that includes general culture and specifically ureaplasma and mycoplasma.[6-8]

Follicle-stimulating hormone (FSH) test

Who to take: Females


When to take: Day 2 of cycle


What is it for: All the relevant hormonal tests must be done to ascertain appropriate balance for optimum results. Without the suitable amount of estrogen, eggs do not mature effectively. 


High follicle-stimulating hormone (FSH) levels suggest possible ovarian failure, or compromised ovarian function. Luteinizing hormone (LH):FSH ratio imbalances can lead to a diagnosis of polycystic ovarian syndrome (PCOS), even when the menstrual cycle is regular. For a similar reason, dehydroepiandrosterone (DHEA), testosterone, free androgen index (FAI), and sex hormone binding globulin (SHBG) are also necessary to be tested.[9-11]


An anti-mullerian hormone (AMH) test is also useful to ovarian research (i.e. the quantity of eggs left — it gives no clue as to the quality of the eggs). Others to be tested are prolactin which guarantees pituitary function for proper signaling and overall hormonal balance, as well as progesterone to discover its baseline.[12-14] 


If only one test can be ordered out of all these, it will be FSH. If a woman’s FSH levels are too high, a pregnancy is unlikely to occur without treatment.[15]

Semen analysis

Who to take: Males


When to take: Anytime (and as soon as possible)


What is it for: It is vital to have your semen analysis performed at a specialist fertility or IVF laboratory. 

In addition, we will request an immunobead test (IBT) to rule out antisperm antibodies. We will also order a sperm chromatin structure (SCSA), DNA fragmentation test, and semen culture to rule out possible infections. This is the best way to ensure male fertility is optimum, so that any couple can achieve peak fertility.[16,17]
