Additional Fertility Blood Tests
Not all fertility blood tests need to be run at a certain point in your cycle. The blood for these tests is usually taken at the same time as either the Day 2-5 or Day 21 tests. These tests look for:
- Testosterone: While most commonly thought of as a male hormone, testosterone in women affects cycle regularity
- Sex Hormone-Binding Globulin : SHBG binds the sex hormones E2 and testosterone. By doing this it limits the free active amounts of these hormones
- Anti-Müllerian Hormone : AMH is produced by the follicles in the ovaries and limits the formation of primary follicles. It is linked to a womans fertility potential and normally reduces as a woman gets older
- Prolactin: This test is usually only done if you have an irregular cycle. It looks to see if there is a problem with your pituitary gland
Further Diagnostic Fertility Tests For Women
For many women, the above tests are enough to determine the state of their ovarian reserve and their current level of reproductive function. If the tests do indicate a problem, your fertility specialist is likely to order further testing to get you a clear diagnosis and help you formulate a plan of treatment or fertility preservation. These are some more advanced fertility tests which can give your fertility specialist valuable information about your reproductive health.

Investigations in Female Infertility
Investigations for anovulation include: FSH, LH, Prolactin, TSH, Testosterone, SHBG, Trans-vaginal U/S, CT/MRI pituitary, Karyotyping.Pituitary and Ovulatory Biomarkers:Common causes of anovulation include polycystic ovary syndrome , hypothalamic amenorrhoea and premature ovarian insufficiency .
- Ovulatory Function: FSH/LH and Oestradiol are essential in assessing the ovulatory cycle. They are best evaluated in the early follicular phase . An elevated FSH level early in the follicular phase is indicative of a low ovarian reserve.
- Ovulation Predictor: evaluating the LH surge is the best single assay, while the measurement of LH plus preovulatory oestrogen is the best prediction.
- Prolactin Testing is required in order to exclude hyperprolactinaemia. It can be measured anytime during the day or in the menstrual cycle . Consider a follow up CT/MRI of pituitary if pituitary macroadenoma is suspected, particularly in the context of amenorrhoea, galactorrhoea, visual field abnormality or headaches, which warrant referral to endocrinology.
- TSH is also recommended to exclude hypothyroidism.
Ovarian Reserve and AMH Testing:
Low serum levels of AMH is suggestive of poor ovarian reserve, whereas high levels may indicate a polycystic ovary syndrome .

Does High Fsh Always Mean Menopause
No, not always. When we are talking about a patient with menopause, the FSH level could be around 50 or even more approximately, so if that patient has that kind of FSH, we could think that maybe the menopause is there, but having 25 doesnt mean that there is menopause. It does mean that your ovarian reserve is quite low, of course, it depends on the moment when that FSH is tested because if you test it, for example, at the end of the cycle, the meaning would be completely different. If we are talking about high FSH 50 or even more, we would think that that patient could be on menopause, but not all the FSH levels mean that the patient has menopause.
Fertility Blood Tests For Women
Having difficulties getting pregnant? Fertility blood tests are likely to be the first tests your doctor sends you for. They are quick and easy to have done, and a few small samples of your blood will check to make sure you arent suffering from any of the following conditions:
- Premature Ovarian Failure : This is a condition where the womans ovaries no longer mature and release eggs. This condition is also referred to as Early Menopause
- Ovarian Reserve: Ovarian reserve is an estimate of the quantity of healthy eggs a woman has left. A low ovarian reserve indicates it may be more difficult to get pregnant because there are less healthy eggs
- Polycystic Ovary Syndrome : One of the biggest reasons for fertility problems, PCOS is a hormonal imbalance that affects the maturation of egg follicles
- Ovulation: This is to make sure that the woman is ovulating , as it is possible to have a regular cycle, but not be ovulating
- Body Weight Affecting Cycle: Having a low body weight can have a negative impact on fertility, but this is not always easy to determine without a blood test, especially with a regular cycle

Any injury to the hypothalamus, or the presence of either psychological or physical stressors, lead to changes in these hormonal cues, resulting in anovulation and amenorrhea.
Ovarian Reserve and Anti-Müllerian Hormone
In females, Anti-Müllerian Hormone is an established biomarker, produced by antral and pre-antral follicles for assessing ovarian reserve, which is considered an important tool in assessing potential fertility. AMH can help in the assessment of reproductive capacity and in the prediction of oocyte retrieval and ovarian responsiveness to stimulation regimes.

When To Test Cortisol
We cant always get a full picture of whats going on with your hormones without looking at the adrenals, which produce the stress hormone cortisol.
Cortisol is involved in your stress response, hair loss, blood sugar regulation and more. In time of stress, the body will shift into preferentially making cortisol over progesterone. Read more about the importance of cortisol here.
Cortisol blood tests are best performed in the morning, along with Adrenocorticotropic hormone , because this is when levels are highest. ACTH is produced in the pituitary gland and helps your adrenals to function. For a more comprehensive picture of adrenal function, a 4-point salivary or urinary cortisol is best. Cortisol can be tested at any time of the month.
Does It Really Matter If You Test E2 Fsh And Lh On Day 3
Since E2, FSH, and LH fluctuate quite a bit throughout the menstrual cycle, youd likely get a totally different value for the same hormone if you tested on any other day. Doctors call day 3 the baseline because thats when E2, FSH, and LH are most stable, before they begin to rise. Aiming to test on day 3 puts you right at the beginning of the follicular phase and is the best time to get a clear read of these baseline levels.
We hear from customers that it can be a bummer to have to wait for your period to test, and we totally get that feeling. It can be hard to wait for this info! While its true that you can technically measure these hormones on any day of your cycle, it wont be clinically meaningful.
Imagine youre checking in with your cardiovascular health and measuring your resting heart rate. If you were just moving around a lot or feeling anxious for any reason, you might expect a higher-than-average heart rate. The heart rate measured at that time wouldnt necessarily be representative of your actual resting heart rate, unaffected by movement or nerves and it might not be the same the next time you measured it.
Another reason why testing your fertility hormones on day 3 is important comes down to reference ranges, which well explain in the next section.

Getting Pregnancy And Fertility Tests
Working with a doctor can help you determine the most appropriate fertility tests for your situation and can ensure that you understand fertility testing, that your sample is collected properly, and that the analysis is conducted by a certified laboratory. Insurance may cover fertility testing when it is prescribed by a physician.
While primary care physicians can perform fertility testing, patients dealing with infertility concerns may also find it helpful to locate a fertility specialist or obstetrician-gynecologist who is experienced in the evaluation and treatment of infertility.
Many types of at-home fertility tests are available. Doctors may recommend at-home urine testing of luteinizing hormone as a quick and helpful way to track ovulation. At-home LH testing involves testing a sample of urine to detect an increase in LH that occurs prior to ovulation. Some doctors my also recommend an Anti-Müllerian hormone or AMH test depending on the circumstances.
Fertility monitors used at home are digital devices that predict ovulation based on electrolyte levels in saliva, LH levels in urine, or a womans basal body temperature. At-home fertility monitors can store information over multiple menstrual cycles to help women better predict ovulation timing and plan for pregnancy.
What If I’m Not Making Enough Progesterone
Firstly, try not to worry! Progesterone suppositories can help increase low progesterone levels and reduce the chances of miscarriage by improving the uterine environment.
If you have a history of pregnancy losses, your doctor may prescribe progesterone supplementation as soon as a pregnancy is confirmed in order to give you the best chance of a healthy, sustained pregnancy.

Overview Of Menstrual Cycle For Hormone Testing
- Day 1 this is the first day you see bright red blood.
- Day 14 this is when women are typically told they ovulate, but thats not true for everyone or every cycle. But we use this as a baseline when discussing lab tests and timing. You should monitor your cycle and symptoms to find out when you *actually* ovulate for sure.
- Day 28 not everyone has a 28-day cycle. However, youll often hear the menstrual cycle talked about in terms of 28 days. This is where your hormones drop if you don’t get pregnant. If youre tracking your period and you know that you have a shorter or longer cycle.
- Back to Day 1 this is when youll once again see blood.
> > Its important to note: While on hormonal birth control you should not ovulate and you dont have a period. Instead, you have a medication-induced withdrawal bleed that isnt actually a period. Some women will continue to ovulate with an IUD.
Can Infertility Be Cured
Sometimes. If your infertility is due to a varicocele, there are outpatient surgeries that you can have that open the vein and allow for the passage of sperm. Injectable, oral, and topical hormones can adjust imbalances and allow for normal ovulation. Sometimes, a doctor can treat your infertility without knowing the cause based on your symptoms and previous health history.
Not all cases of infertility can be successfully treated, however. If youre struggling to conceive, your doctor might suggest you try IUI or IVF to help you get pregnant.

Hormones After Embryo Implantation
Once implanted, the embryo must make its presence known, biologically, to the mother. This is achieved via the hormone, hCG . hCG is released around the 6th day by the fertilised egg. It increases kidney function to eliminate biological waste more efficiently. However, this means that urination is more frequent. hCG, interestingly, is also the first major chemical confirmation that pregnancy has begun. It is used in pregnancy tests as some of it will drain into the bladder.
Oestrogen and Progesterone maintain their importance even after implantation, however they are now also created by the placenta. The placenta is formed about four weeks into pregnancy, around the same time that the highly coveted baby bump makes an appearance. Half of the developing cells are recruited by the body to become the placenta, the go between for the parent and the child. As mentioned earlier, hormones can have a multitude of effects in the body due to their ability to access every part of the body via the blood. Although their primary roles are fundamental to the development and health of the baby, the side effects can be unpleasant.
Oestrogens role in increasing blood circulation can also have adverse effects. Skin can turn red and blotchy due to the overuse of capillaries near the skin surface. Increased circulation of this nature can also lead to headaches and congestion of the sinus.
Is It Safe To Simulate With Fsh Higher Than 300 Units
I wouldnt say that its not safe, of course, it is safe, but the issue that we should consider is whether its useful or not. When we have a patient with a really low ovarian reserve, we could give, I dont know, 600 units if we want because the issue is that there are no receptors in the ovaries to make that medication work properly. In the end, we know that giving a stimulation of more than 300 units doesnt make any sense because the effects wont be so good. The ovaries are not having a good number of follicles and are not having any good number of receptors in where those medications could act. If we give that a high dose of stimulation, the idea is to try to make the ovaries work as much as possible but using more than 300 units nowadays, its not very common because we know that the results wont change at all.

Discover Why Fertility Bloodwork Is An Important Step On The Path To Parenthood
Fertility bloodwork is integral to the care we provide at our Southern California fertility center. This bloodwork tests for a number of fertility hormones that offer insights that can help our team identify the type of fertility challenges a patient might have. We also use bloodwork when monitoring patients during fertility treatments. This monitoring shows how a patient is responding to various medications.
Can Stress Cause Low Ovarian Reserve
I couldnt say that stress may cause a lower reserve. What is known is that stress could affect some sort of hormones suppression. If the patient is going through a stressful moment, hormones like FSH and so on could work differently because the brain is related to one thing and the other. The stress itself wouldnt cause lower ovarian reserve. In some stressful situations, it may cause amenorrhea which means that menstruation doesnt come. Because of the alterations that the brain would have in a stressful situation, in the FSH, LH production, in the end, stress wont cause a lower ovarian reserve itself, but of course, it could cause some alterations in some hormones.

What Is Prolactin Hormone
Prolactin, also known as PRL or lactotropin, is a hormone that is responsible for functions such as lactation, milk production, certain breast tissue development and more . In short, this hormone causes your breasts to grow and produce milk.
It is produced primarily in our pituitary gland, though your central nervous system, uterus, immune system and other glands are also able to produce prolactin . Dopamine and oestrogen, control the production and release of prolactin from the pituitary gland .
What Is The Purpose Of Taking Fsh And Lh For Daily Simulation If The Lh Is For Ovulation
LH is also involved in follicular growth, so normally, when we are stimulating the ovaries, we start with FSH or a kind of FSH to stimulate follicular growth. Sometimes, we add some kind of LH, especially in older patients that should use LH action to try to make the follicles grow in a better way. We are trying to make the ovaries produce more follicles. We normally produce just one follicle in a natural cycle, and the idea is to try to make the ovaries produce more follicles. We are making FSH or LH go to the receptors in the external part of the follicles, and were making those follicles grow. When they grow properly we know that we are going to retrieve around 5 eggs which is not a natural situation that we may find in a natural cycle. We do that to retrieve a higher number of eggs.

How Can You Pinpoint Day 3 Of Your Cycle
There are a couple of things to keep in mind when pinpointing your day 3. First, youll count day 1 as the first day you experience full flow, not just spotting, before 5pm. You can think of full flow as enough flow to need a tampon, pad, menstrual cup, or other menstrual product. If you spot on Monday and Tuesday, then start getting enough flow to need a menstrual product on Wednesday, youll count Wednesday as day 1. This would put your day 3 as Friday.
Another handy thing to know is that unless you have a super-short period, there are actually a few days that are okay for testing. Through having hundreds of conversations with customers, weve found its easiest to have a single day to aim for this is why we lead with talking about day 3 testing. But you can take your test on days 2, 3, or 4 and get accurate results, as long as youre still bleeding. If your period is really short , you should test on day 2.
