Synopsis
Many individuals mistakenly believe that female infertility is solely to blame for the inability of couples to conceive. In fact, male infertility also plays a large role when it comes to infertility; many unknown factors can cause infertility within both men and women. There are different types of fertility tests for women: measuring hormone levels in the body, counting the number of eggs in a woman's ovaries, and assessing the health of her reproductive organs. There are also tests for males that evaluate the quality and quantity of their sperm. In this article, we will discuss fertility tests for males and females, their timing, and how these tests help diagnose infertility.
What are fertility blood tests?
A fertility blood test consists of several blood draws to determine your hormone levels and assess the functioning of your reproductive system. The testing procedure itself is relatively simple: You'll typically visit the laboratory in the early morning hours, provide a few small vials of blood, and then wait for the test results. When your results are available, you will have a better understanding of your reproductive health based on the results of the fertility blood test.
When are fertility blood tests done?
There’s nothing wrong with using fertility blood tests to figure out what’s happening with your body and get ahead of anything that could affect your ability to conceive naturally or through in vitro fertilisation (IVF). Fertility blood tests aren't only for couples trying to get pregnant after years of trying or for women and men considering IVF; they can also be helpful for anyone interested in learning more about their body, including women looking to enhance their fertility. Fertility blood tests are done in the following cases:
- If you’re trying to conceive, and it’s taking longer than you expected, a fertility blood test gives you the chance to see if you are ovulating regularly or if you need to take a closer look at potential issues, such as hormonal imbalances.
- If your menstrual cycle is irregular or doesn’t happen every month, there are ways to narrow down the cause, which may be hormonal imbalances.
- If you’re considering freezing your eggs, fertility testing should be performed before egg freezing (A.M.H. testing) and some hormone testing to determine how many eggs are in reserve and what the best time frame is for egg freezing.
- If you’re in a same-sex relationship or using a donor, you still need to know how your hormones are behaving, no matter what method you choose to conceive - either through natural means or via assisted reproductive technologies (ART).
- A lot of individuals complete a fertility analysis before they even think about having children. Many are simply curious about their current fertility and future options.
- A simple blood test for men’s hormones can give an early indication of any factors that may be detrimental to sperm health.
Female Fertility Blood Tests
A brief description of some of the most common tests that can be performed on women regarding their menstrual cycle and overall health.
- The use of FSH testing involves the measurement of the amount of FSH present in the woman’s blood within 2 or 3 days of her cycle. Elevated FSH levels may indicate reduced ovarian reserve; however, normal FSH levels suggest adequate ovarian function.
- LH levels are considered a marker of whether a woman will ovulate. When a woman has both LH and FSH measured during the same cycle, it is common for LH: FSH ratios to be elevated in women with polycystic ovarian syndrome (PCOS).
- Estradiol measures the amount of estrogen produced by follicles and also helps interpret the results of FSH testing. When elevated E2 levels are present in the early part of a woman’s menstrual cycle, they can mask elevated FSH levels and indicate a diminished ovarian reserve.
- AMH can be tested at any point during a woman’s menstrual cycle and indicates how many eggs are still being produced by the ovaries. AMH has been used to provide an estimate of response to ovarian stimulation; however, it does not provide a direct indication of natural pregnancy.
- Testing of progesterone is usually performed approximately one week after a woman has ovulated. The presence of progesterone in a woman’s blood confirms that ovulation has occurred and provides an indication of whether or not she has an adequate luteal phase. Low progesterone levels are an indication that a woman has either not ovulated or that she has a luteal phase defect.
- Prolactin testing allows a woman to determine whether she is experiencing elevated levels of this hormone that may interfere with her ability to ovulate. Stress and conditions affecting the pituitary gland often cause elevations in prolactin levels.
- TSH is a useful measure of thyroid function because both hypo- and hyperthyroidism can affect a woman’s menstrual cycles and increase her risk of miscarriage.
- Testing for androgens (Testosterone and DHEAS) provides information regarding a woman’s levels of female hormones in relation to male hormones. This type of testing assists in diagnosing PCOS and other endocrine disorders.
Men's Fertility Blood Tests
Men's fertility is typically assessed through sperm analysis; however, if semen tests reveal low sperm counts, testosterone blood tests can help identify possible reasons for the low count.
- High levels of FSH hormone may be associated with reduced sperm production.
- Testosterone is essential for both the production of sperm and the drive for sexual performance.
- LH regulates the level of testosterone.
- Abnormal Prolactin and thyroid levels can cause hormonal imbalances, which can harm both sperm production and sexual ability.
Conclusion
Blood tests for fertility are a crucial aspect of understanding fertility, but they do not provide all of the information needed to understand fertility. Interpreting results from these tests and using them to establish diagnoses, create treatment plans, and set appropriate expectations can help you achieve your desired results. This knowledge empowers women, regardless of where they are in their fertility journey, to take an active role.
Frequently Asked Questions
Can a woman use fertility blood tests to identify if she will become pregnant or not?
Female fertility tests can measure hormone levels and ovarian reserves, but they cannot identify if a woman will be pregnant or not.
When should I go for fertility blood tests again?
In cases where a woman has borderline results or her treatment plan requires updated laboratory results, the doctor may recommend repeating the test.
When are fertility blood tests done?
Fertility blood tests are typically performed on Days 2-3 of the menstrual cycle, except for AMH and thyroid tests, which can be performed at any time during the cycle.
Does the male partner have to take fertility tests?
Generally, men have their semen tested first, and if the results show any abnormalities, further testing may require blood tests.
Do stress levels affect fertility blood test results?
Stress may negatively affect hormone levels, such as prolactin and cortisol, which would, in turn, influence the findings from the fertility blood test.
