宫内人工授精, 人工授精:人工授精的方法, is the process of preparing and delivering a highly concentrated amount of active, motile sperm directly through the cervix into the uterus. Typically, IUI is performed while a woman is taking 刺激排卵的药物. The procedure is commonly used as a low-tech, cost-effective way to enhance fertility.
宫内人工授精
评估和测试
Before beginning IUI treatment, women must undergo an X-ray test, called a 子宫输卵管造影, to document that they have at least one open fallopian tube.
Male partners providing a semen specimen for IUI must be tested for infectious diseases. If a woman is using donor sperm from a sperm bank, she must be tested for infectious diseases before beginning donor sperm inseminations. 所需的具体检测是艾滋病毒, HTLV我, 梅毒检测, 乙型肝炎表面抗原, 和丙型肝炎抗体. This testing is required by California state law. 在IUI执行之前, the tests must be complete and our office must have received the results. 这项政策没有例外.
Depending on the blood laboratory you use and the doctor who orders the testing, test results can take anywhere from seven days to four weeks to arrive in our office. We recommend completing these tests as soon as possible to avoid added stress at treatment time. You're responsible for ensuring that these lab tests are in your medical records at UCSF. Once testing is complete, women can waive repeat testing for subsequent treatment cycles, if needed.
过程
There are several ways to prepare sperm for IUI, all of which involve separating sperm from seminal fluid. It's not possible to inject semen that hasn't been separated directly into the uterus, as chemicals in the fluid can cause extremely painful uterine contractions.
At UCSF, we primarily use a method of sperm separation called 密度梯度分离. 在这个技术中, motile sperm are separated from dead sperm and other cells through the use of viscous solution. This process takes approximately two hours.
后准备, the sperm concentrate is placed through the cervix into the uterus using a thin, 灵活的导管. The procedure takes about five to 10 minutes. The patient may experience mild cramping, but that should go away shortly after the procedure is completed.
There is a small risk of infection following IUI — less than 1 percent.
提高成功率的药物
Studies suggest that IUI success rates are enhanced if the woman also undergoes moderate treatment with medications. 要做的决定 刺激卵巢的药物 would be made in consultation with your doctor.
Most patients start with either clomiphene citrate or Letrozole oral medications, taken for five days shortly after menstruation begins. 另外, you might be advised to take injectable fertility drugs, which are more aggressive in stimulating multiple egg release. The more eggs you produce during a treatment, 你成功的机会就越大, 但也, the higher your chance of a multiple pregnancy.
