Many women become pregnant easily, but for others, this may require some assistance. ZRT’s Fertility Profile can help both men and women with infertility if you:

  • Have hormonal symptoms
  • Have been trying to conceive for more than six months
  • Are you in your mid 30's or older
  • Have had difficulty sustaining pregnancy in the past
  • Know infertility runs in your family
  • Want to assess your fertility status


If you’ve been trying to get pregnant without success, you are not alone. A large number of women are having difficulty trying to become pregnant. The most recent National Survey of Family Growth showed that in the U.S. the average infertility rate was 21.4% in married women aged 30-44 years who had not yet had any children. Further, the study also found that a staggering 32.2% of married women had difficulty sustaining a pregnancy (known as fecundity). While nearly half of infertility in women can be attributed to physical causes such as not producing an egg (ovulatory failure 21%), damage to the tubes that carry the egg to the uterus for fertilization and implantation (tubal damage 14%), and problems with the uterine lining (endometriosis 6%), a massive 28% of cases are left unexplained. In the absence of a physical cause, many cases of female infertility may be explained by something as simple as a hormonal imbalance, which can be detected by hormone testing and easily corrected by diet, lifestyle changes, or hormone therapy.



Progesterone produced by the ovaries during the second half of the menstrual cycle is essential for preparing the uterus for implantation of the fertilised egg. In some patients, ovulation and fertilisation of the egg may occur normally, but progesterone is not produced in sufficient amounts to sustain the pregnancy.


Low levels of the thyroid hormones fT3 and fT4 may prevent ovulation, which can be indicated by no periods or irregular cycles. Autoimmune thyroid issues, resulting in elevated levels of antibodies to the thyroid gland can increase the risk of miscarriages.


PCOS affects between 6% and 15% of women during their reproductive years. PCOS is a common cause of ovulation problems, weight issues, and miscarriages. Once PCOS is recognised and treated, many women are able to become pregnant.


Declining egg production is the primary reason for the age-related decline in fertility. A low egg reserve can also be caused by premature ovarian failure.


Stress affects ovulation due to its effect on the endocrine system. High cortisol can inhibit ovulation, whereas low cortisol can affect the immune changes necessary for implantation to occur. Stress may also lead to the development of endometriosis, which is found in more than 50% of women with unexplained infertility.


We offer a simple, cost-effective test that can identify treatable hormonal imbalances and point to other serious health issues that affect fertility. Early detection can help your health care provider address these issues, and can also identify the need for more specialized care without spending additional time attempting to become pregnant through traditional methods.

We understand your busy schedule, which is why ZRT developed simple and convenient methods for testing in the privacy of your own home, at the optimal time. This is important as collection must be done on two different days during your cycle. ZRT’s test eliminates inconvenient, stressful, and time-consuming trips to the blood draw clinic. ZRT’s fertility profile tests 15 distinct hormones to help assess fertility. Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH) are tested at the beginning of your cycle. During this time the following can be seen in women with infertility:

  • High FSH on day 3 reflects low egg reserve
  • High LH relative to FSH can indicate PCOS

Near the end of your cycle, Estradiol (E2), Progesterone (Pg), Testosterone (T), DHEA-S (DS), Cortisol (4x), Sex Hormone Binding Globulin (SHBG), and thyroid hormones (free T4, free T3, TSH, TPO) are measured.

During this time the following can be seen in women with infertility:

  • Low estradiol and progesterone are typically seen in women with low egg reserve.
  • The ratio between estradiol and progesterone can indicate no ovulation or luteal phase deficiency.
  • High levels of DHEA-S and Testosterone can suggest the presence of PCOS
  • Thyroid problems can suppress ovulation and contribute to early miscarriages 
  • Abnormal cortisol patterns reflect stress, which can affect your ability to conceive.

Vitamin D is available as an optional test with the Fertility Profile. Recent research has shown women with low levels of vitamin D are less likely to become pregnant after in vitro fertilisation.


At ZRT, we understand that infertility affects many women today, and we developed the fertility profile to help your health care provider find the underlying causes. Our accurate testing ensures you receive results that will bring you one step closer to solving the issue of your infertility. Convenience: Collection is done in the privacy of your own home, at the optimal time. This eliminates inconvenient and time-consuming trips to a clinic for blood draws. Turn-Around-Time: 95% of test results are completed and available within five business days. Reporting: ZRT’s comprehensive test report includes your hormone levels and takes into account your reported symptoms, medications, and hormone usage. Results are reviewed by ZRT’s licensed physicians and descriptive comments are included with the test report.
