Blood Tests

Blood tests are ordered so a doctor can get a better understanding of a patient’s overall health prior to moving forward with fertility treatment. They reveal blood type, check for possible hormonal imbalances and determine whether a patient (or partner) carries any genetic or infectious diseases or antibodies - all of which can affect the health and outcome of a pregnancy.

Hormones That Affect Fertility in Women

Hormones control every step in achieving pregnancy, from stimulating the development of an egg to ovulation and implantation of a fertilized egg in the uterus. Each hormone that plays a role in conception must be produced in a specific amount at a precise time in a menstrual cycle. Hormonal studies measure the levels of certain hormones produced during a cycle. Blood test results, along with other testing, will help determine the best treatment options.

Hormones That Affect Fertility in Women

Hormones that control ovulation and implantation of the egg are:

Estradiol stimulates the growth of the follicles and the production of fertile mucus from the cervix, and prepares the uterine lining for implantation of a fertilized egg.

The level of Anti-Mullerian Hormone (AMH) in a woman’s blood is generally a good indicator of ovarian reserve.

Follicle-stimulating Hormone (FSH) stimulates the development of the egg.

Luteinizing Hormone (LH) stimulates the release of the egg from the follicle (ovulation).

Progesterone stabilizes the uterine lining for implantation of a fertilized egg and supports early pregnancy.

Normally, small amounts of androgens — testosterone and DHEAS (dehydroepiandrosterone sulfate) — are produced in women. Excess production may interfere with development of the follicles, ovulation, and cervical mucus production.

Prolactin stimulates milk production. Blood levels may be higher than normal in certain disorders or if you are taking certain medications.

An under-active thyroid (hypothyroidism) can result in high prolactin levels.
