The main reason for performing a hormone evaluation is to gain a basic estimate of the number of eggs (oocytes) a woman has and her ability to release eggs from her ovary (ovulate). The two tests that allow us to assess the number of oocytes and reproductive “age” of a woman are the Anti-Mullerian Hormone (AMH) which can be checked at any day during your cycle and the Follicle Stimulating Hormone (FSH) which is checked on day 2-5 of your cycle. These two test can be used to determine the amount and type of medication used, and also determine if Timed Intercourse, Intrauterine Insemination (IUI) or In Vitro Fertilization (IVF) is the appropriate option for treatment. Thyroid hormones (TSH & T4), Prolactin (PRL) and Testosterone levels may be checked as well, depending on your history, because abnormalities in these hormone levels can interfere with ovulation, cause irregular or heavy menstrual cycles and increase the chance of a miscarriage. Abnormal levels of these hormones are typically treated with medication alone.
