we test your blood for several levels to determine if you, your partner, or both of you are struggling with infertility.
follicle-stimulating hormone (fsh) helps control a woman’s menstrual cycle and the growth of follicles, which produce eggs. the blood test is done on the second or third day of your menstrual cycle, and is used to evaluate egg supply and ovarian function. in men, fsh regulates the production and transportation of sperm. the test helps determine sperm count.
estradiol is an important form of estrogen. an estradiol test is used to measure your ovarian function and to evaluate the quality of your eggs. like fsh, it is done on the second or third day of your menstrual cycle.
luteinizing hormone (lh) level
in women, luteinizing hormone (lh) is linked to ovarian hormone production and egg maturation. a luteinizing hormone test performed at the beginning of your cycle may help diagnose hormonal imbalances, like pcos. when lh testing is performed midway through your menstrual cycle (day 14 of a 28-day cycle), the level shows when you’re producing eggs. in men, lh stimulates the hormone testosterone which affects sperm production. an lh test helps diagnose male-factor infertility.
thyroid stimulating hormone (tsh)
tsh is the brain hormone that controls thyroid hormone production in the body. thyroid function is critical to many processes and is extremely important in the regulation of fertility.
anti-müllerian hormone (amh)
secreted by follicles in the ovary, amh is present until a woman reaches menopause. testing amh gives us a good understanding of your ovarian function and egg reserve. lower amh levels can predict a lower egg yield and thus, a lower chance of success in ivf. amh can be tested at any point in your menstrual cycle, and can also be done if you’re taking oral contraception.
progesterone is a female hormone produced by the ovaries during ovulation. it prepares the endometrial lining of the uterus and makes it receptive to fertilized eggs. a serum progesterone test is used to determine if ovulation is occurring. since progesterone levels increase towards the end of a woman’s cycle, the test is done right before your period starts.
the hormone prolactin is made by the pituitary gland and causes milk production. in women, a prolactin test may be performed in the evaluation of infertility, to determine why a woman is not ovulating or when a woman has symptoms, such as nipple discharge. in men, a prolactin test is done when there is a lack of sexual drive or when there is difficulty getting an erection.
testosterone is probably the most well-known androgen and affects the fertility in men and women. in women, an androgen test is used in the evaluation of conditions including polycystic ovarian syndrome (pcos). in men, an androgen test is used to find the cause of low sex drive, the inability to get an erection, or infertility.
