What is intrauterine insemination (IUI), and when is it recommended?
Intrauterine insemination (IUI) is a popular fertility treatment that involves placing sperm directly into the uterus during the woman’s ovulation period to increase the chances 大阪市西区 不妊治療 fertilization. It’s often used in conjunction with ovulation-inducing medications to enhance the chances of success.
How IUI Works:
- Sperm Collection and Processing: In IUI, the sperm is collected from the male partner or a sperm donor. The sperm is then processed and concentrated to remove impurities and improve motility (movement).
- Timing of Insemination: The woman is closely monitored during her menstrual cycle to determine the optimal time for insemination, which is usually when ovulation occurs. Ovulation predictor kits, blood tests, and ultrasounds are commonly used to track follicle growth.
- Insemination Procedure: Once ovulation is confirmed, the prepared sperm is injected directly into the woman’s uterus using a thin, flexible catheter. This procedure is typically quick and painless, though some women may experience mild cramping or discomfort.
When is IUI Recommended?
IUI is generally recommended for couples with mild fertility issues. It can be particularly effective in the following cases:
- Male infertility: IUI is often recommended for men with low sperm count or poor sperm motility.
- Unexplained infertility: IUI may be considered when the cause of infertility is not easily identifiable, but conception has not occurred after a year of regular, unprotected intercourse.
- Ovulation disorders: Women with irregular ovulation, such as those with polycystic ovary syndrome (PCOS), may benefit from IUI, particularly when used alongside medications like clomiphene citrate to stimulate ovulation.
- Cervical issues: If a woman’s cervical mucus is hostile to sperm, IUI can bypass this barrier by delivering sperm directly into the uterus.
- Same-sex couples or single women: IUI is also an option for same-sex couples or single women who choose to use donor sperm.
IUI is generally considered less invasive and less expensive than IVF. However, the success rate is lower, particularly for women over 35 or those with more severe fertility issues.
