However, as with many medical tests, some problems can occur with having blood drawn, like:. Having a blood test is relatively painless. Still, many kids are afraid of needles. Explaining the test in terms your child can understand might help ease some of the fear. Allow your child to ask the technician any questions he or she might have. Tell your child to try to relax and stay still during the procedure, as tensing muscles and moving can make it harder and more painful to draw blood.
It also may help if your child looks away when the needle is being inserted into the skin. Larger text size Large text size Regular text size. What It Is Follicle stimulating hormone FSH is produced by the pituitary gland, a pea-sized gland in the brain that plays an important role in sexual development. Why It's Done Doctors may order an FSH test if a boy or girl appears to be entering puberty earlier or later than expected.
In adults, FSH levels can also help doctors evaluate fertility issues and menstrual problems. Preparation No special preparations are needed for this test. AMH levels can be drawn at any time during the menstrual cycle.
It can be difficult to compare results from one laboratory to another. This test involves taking a medicine called clomiphene citrate to see how the ovaries respond. It is given early in the menstrual cycle. Women have lower pregnancy rates with both ovulation induction therapy and IVF if their FSH levels are high at either time.
A transvaginal ultrasound may be done in the early part of the menstrual cycle to count the number of small 2mmmm follicles in the ovary. These are called antral follicles, and are where eggs develop. This test is more accurate when it is done by a health-care provider who is experienced in working with fertility evaluations.
Gonadotropins are hormone medications FSH alone or FSH with luteinizing hormone that are given to stimulate the ovary to grow multiple eggs at once.
They are given by injection to prepare a woman for fertility therapies. Higher doses of these medicines are usually needed to help with egg development as a woman gets older.
Women who require large, or larger than expected, amounts of gonadotropins generally get pregnant less often with both ovulation induction therapy and IVF. The nurse will take a blood sample using a needle, and it will be sent to a lab for analysis. Eliminating all other factors, the higher the follicle count, the better patients might do. To understand your FSH test result, remember that generally, a lower number is better—meaning the lower the FSH, the greater the ovarian reserve.
Other factors are almost always at play, and FSH is just one piece of your reproductive puzzle. Plus, your FSH level reported by one lab may not correlate to that from another. For example, if your FSH levels are normal, but you have another issue—such as a partner with a low sperm count, a uterine problem, or an egg or embryo quality issue—then the other issue would need to be addressed in your fertility journey.
