Follicle Stimulating Hormone (FSH)
FSH stimulates the follicles (sacs which contain eggs) within your ovaries to begin preparing for the release of the egg. High levels of FSH are generally an indicator that egg reserves are running low.
Luteinizing hormone (LH)
LH works together with FSH in helping egg follicles develop. It also plays a key role in acting as the trigger to the final development and release of the egg at ovulation.
Prolactin is released by the pituitary gland and stimulates lactation i.e. production of breast milk. Abnormally high levels of prolactin may interfere with the process of ovulation and conception.
Progesterone is produced from the ovary following ovulation. Progesterone levels will be at their peak about a week after ovulation. Elevated levels of progesterone in the blood stream at this time suggest that ovulation has taken place.
Anti-Müllerian hormone (AMH)
AMH is produced by small follicles (sacs containing eggs) in the ovary. The AMH level drops steadily as women move from puberty to menopause. When a woman reaches menopause her egg supply will have been depleted and there will be no detectable AMH in the blood stream. AMH has proven to be very helpful for fertility doctors in advising women with fertility problems as to when they should consider fertility treatment and in choosing the optimal medication dose & regime.
Additional Blood Tests
In certain situations you may be asked to undertake other blood tests while in treatment. These include testosterone, androstenedione, SHBG, DHEAS, lupus screen, anti-cardiolipin antibodies, thrombophilia screen and karyotype. However only selected women require these tests.
